PREMIUM/286 AND 386 THIRD FLOPPY SUPPORT
The following summarizes installation considerations for a third floppy device
in AST Premium Computers:
PREMIUM/286 HARDWARE CONSIDERATIONS
PREMIUM/286 systems equipped with part number 202143-003 or 202143-004 system
boards include embedded diskette drive controller circuitry that allows
support for a third floppy device. The third floppy is connected to the 34
pin connector on the system board with an additional floppy drive controller
cable (AST part number 220085-001). The cable is attached to the third floppy
device and the 34 pin connector J20 on the system board.
PREMIUM/386 HARDWARE CONSIDERATIONS
All PREMIUM/386 system boards are built with embedded third floppy diskette
control circuitry. The same cable (AST part number 220085-001) is required to
install the third floppy device. This cable connects to the P4 connector on
the 386 system board.
SOFTWARE CONSIDERATIONS
Because the third floppy device is not directly recognized by the system BIOS,
two device drivers, DRIVER.SYS and ASTDSK.DRV, must be inserted into the
CONFIG.SYS file.
DRIVER.SYS is provided with MS-DOS Version 3.3 Release 1.3 and ASTDSK.DRV is
provided on the AST Utilities diskette shipped with all PREMIUM systems.
DOS VERSIONS
AST recommends and supports the use of AST MS-DOS Version 3.3 Release 1.3.
For best results, users of earlier DOS versions should upgrade to Version 3.3
Release 1.3. Contact your local AST Service Center for additional
information.
INSTALLATION
The AST Utilities Diskette provides menu-driven automatic installation of the
third floppy device drivers into the CONFIG.SYS file. The following are the
configuration commands for each of the possible hardware combinations.
The commands listed below are supported under DOS Version 3.2 and 3.3 unless
otherwise noted:
For 360 KB drive (5.25-inch diskettes)
DEVICE=C:\DOS\ASTDSK.DRV 0
DEVICE=C:\DOS\DRIVER.SYS /D:2 /F:0
For 720 KB drive (3.5-inch diskettes)
DEVICE=C:\DOS\ASTDSK.DRV 2
DEVICE=C:\DOS\DRIVER.SYS /D:2 /F:2
For 1.2 MB drive (5.25-inch diskettes)
DEVICE=C:\DOS\ASTDSK.DRV 1
DEVICE=C:\DOS\DRIVER.SYS /D:2 /F:1 /S:15
For 1.44 MB drive (3.5-inch diskettes)
DEVICE=C:\DOS\ASTDSK.DRV 3
DEVICE=C:\DOS\DRIVER.SYS /D:2 /F:7 /S:18
(use /F:3 for DOS 3.2)

AST-3270/FTS-C FUNCTIONAL ISSUES
AST Product Marketing has reviewed all of the open issues relating to this
product. They have made the decision that the following issues will not be
resolved.
This product has been discontinued by AST. No further enhancements will be
made to this product.
These issues are:
- User cannot upload files to a TSO host properly. If the customer tries
to upload information to an existing partitioned data set and a non-
existing member, he receives the error message "UNABLE TO TERMINATE
INPUT MODE". If neither the data set nor the corresponding member
exist on the host, the file transfer will work for the first member
only. (PR#A32006)
- User cannot transmit more than one file to the host during a file
transfer session. The first file transfers okay, but after entering
the second file name, the error message from the host "IKJ56712I-
INVALID KEYWORD, LISTDS IKJ560703A-RE-ENTER" is displayed. The file
transfer software displays the message "Unable to open dataset".
(PR#A32007)
- With FTS-C version 1.31, user is reporting intermittent problems when
attempting to upload files of greater than 64K in size. The host is an
IBM 4381 running CMS under VM/SP release 5. When FTS-C attempts to
close the uploaded file, the error message "NON-RECOVERABLE HOST ERROR,
FTS ABORTED" is displayed. (PR#A32011)
- When attempting file transfer on an MVS/XA TSO/ACF2 host, the error
message "Unable to list TSO profile" message is received when the file
upload is commenced. (PR#A32012)
- When performing file uploads to the host, user says that FTS-C sends
screens of data faster than the host can process them. The software
does wait for an acknowledgement from the host that the first screen
was received, but does not wait to send ensuing screens of data. The
host is operating under MVS/XA TSO. (PR#A32013)
- When using FTS-C software with a mainframe configured with TSO/E
version 3.0, downloading of files does not occur correctly. Parts of
records are either truncated or missing altogether. Problem occurs
with files of larger than 10K in size. (PR#A32008)
- "Unrecoverable host errors" occur on a host operating under VM
release 5 with a multi-session manager called "VTERM" installed.
Errors occur at end of file transfer session as files are being
downloaded. (PR#A32014)
- Packed record formats are not supported with FTS-C. When the
software encounters the LRECL parameter value of "1024" (for packed
files) the error message "record length greater than 255" is
generated. (PR#A32015)

AST-5250 ASYNC DIAL-UP FUNCTIONAL ISSUES
AST Data Comm Product Marketing has reviewed all aspects of the following
functional issues relating to the 5250 Async Dial-up product (part number
500307-001). They have made the determination that these issues will not be
resolved for this product.
These issues are as follows:
- The user is sharing one session between the master and slave systems.
This device is also used as a sub-console. When a change is made to
the screen of the slave, such as a change of menu, the screen takes
about 30 seconds to completely refresh on the slave. (PR#A46011)
- A job sent from the IBM System/36 to a printer attached to an Async
Dial-up slave may appear to operate very slowly. The printer will
print two lines, pause, then print two more lines. The Async Dial-up
product is however, operating as designed. (PR#A46015)

AST-5251/11 ENHANCED FUNCTIONAL ISSUES
AST Data Comm Product Marketing has reviewed all aspects of the following
functional issues relating to the 5251/11 Enhanced product (part number
500417-XXX). They have made the determination that these issues will not be
resolved for this product.
These issues are as follows:
- An application from IBM for use on the IBM AS/400, called "AS/400
OFFICE", will not operate when used on a terminal which is configured
using the Enhanced emulation software. When the program is loaded,
data on the screen is garbled. (PR#A45129)
- The 5251/11 Enhanced board does not function correctly when installed
in a system with an Orchid "Tiny Turbo" card. The 5251/11 software
reports various errors such as "Internal stack overflow" and
"Unidentified error". (PR#A45059)
- The user is printing a job sent from the System 36 to a printer
attached to the PC which is emulating an IBM system printer. If during
the job the printer is powered down, upon re-starting the printer the
rest of the printed data is unintelligible. (PR#A45092)
- The utility ASTKBD.EXE may corrupt the AST5251.KBD data file, if
changes are made to the keyboard configuration and the changes are
written over the existing AST5251.KBD file. (PR#A45081)
- The Enhanced card does not appear to operate correctly when installed
on a line with the IBM 3197 terminal. If the Enhanced card is the last
device on the line, and the IBM 3197 terminals in front of it are
operating then the system with the Enhanced card in it may lock up.
(PR#A45101)
- The 5251/11 Enhanced product does not operate in a Toshiba 5100 PC. The
user gets a blank sign-on screen with "SA" highlighted. The emulation
does not work at any system speed. (PR#A45036)
- The keyboard mapping of the 11/Enhanced product does not work correctly
on the Wyse Models 2200 and 2214. The keypad, cursor arrow keys, and
right "control" key do not operate as they are supposed to. (PR#A45057)
- Emulation does not function correctly in the Commodore PC-10 compatible
computer. System locks up when more than one error message is received
from the System 34. (PR#A45063)
- The 11/Enhanced product does not work correctly in the DTK XT-clone
system. It may be necessary to disable the PC's clock to allow
emulation to operate. (PR#A45113)
- With 11/Enhanced board operating in a Unisys PC with a Persyst CGA
adapter, there is more than the normal amount of "snow" on the
emulation screen. The "no snow" option in the configuration program
does not have any affect on the problem. (PR#A45118)
- The 5251/11 Enhanced software does not support the Keytronics 122-key
keyboard. The right hand "Control" key and the PC "Enter key" issue
the same scan code in DOS. For this reason these two keys cannot be
mapped to different functions by the AST emulation software.
(PR#A45116)
- When running emulation program in EGA mode, all screen attributes that
should appear as yellow on the screen actually appear as a shade of
brown. (PR#A45168)

AST-5251/11 FUNCTIONAL ISSUES
AST Data Comm Product Marketing has reviewed all aspects of the following
functional issues relating to the 5251/11 product (part number 500222-XXX).
They have made the determination that these issues will not be resolved for
this product.
These issues are as follows:
- The user is attempting to use virtual print, to print a DisplayWrite 4
document. When trying to print to a 5219 printer, bold character codes
are being interpreted as blank spaces. (PR#A00147)
- User has 5251/11 cards in IBM XT's and XT clones. User has found that
after signing on the System 38, the systems with these cards will
randomly lock up. Removing the hard disk and controller seems to
resolve the problem. (PR#A00154)
- User has a VGA display adapter installed in conjunction with the 5251/11
card. During a cold boot of the system, the 5251/11 KERNEL program
fails to load, with an error code "5". However, during a warm boot
KERNEL successfully loads. (PR#A00181)
- The use of the Hewlett Packard LaserJet II is not fully supported with
the 5251/11 software. This means that the LaserJet II cannot be used to
emulate all functions of a true IBM System 3X printer when attached to a
PC running the AST emulation program. (PR#A00188)
- The 5251/11 adapter does not operate in a Magitronics 12MHz AT clone.
When emulation software is executed, only a blank sign-on screen
appears. The "SA" is not highlighted in the status area, and the cursor
remains in the upper left-hand corner. (PR#A00185)
- 5251/11 does not support Epson LQ850 and LQ1050 printers because
Vertical Motion Index units of n/60 are not recognized by the emulation
software. (PR#A00192)
- Under 5251/11 emulation, a Hewlett Packard LaserJet II printer is
configured as an IBM 5224 Model 1 printer. When printing any system 36
application, one or more blank pages (depending on the application) are
ejected after every form feed, which is not normal operation for this
type of printer. (PR#A00171 and PR#A00196)
- The 5251/11 emulation is installed in an "AT" type system which has
Award 3.03 BIOS. When loading the emulation software, an error code "2"
or "3" is generated, and software cannot be executed. (PR#A00189)
- Displaywrite/36 documents do not print correctly through 5251/11
emulation. The PC printer emulating a host printer does not recognize
the right margins of the Displaywrite/36 document. Also, when printing
a legal (8.5 by 14 inch) document, the PC printer does a form feed at 11
inches. (PR#A00150)

5250 FILE TRANSFER ON THE IBM AS/400
These requirements must be met before using AST 5250 File Transfer software
on the IBM AS/400:
- The AS/400 library named QSYS38 provides the functions needed for the
System/38 environment. This library must be present and added to a
user's library list before using the AST 5250 file transfer software.
Without these functions the software will fail to initialize and
generate function check errors.
- A period occurring in the name of a file which is to be either uploaded
to or downloaded from the AS/400 will cause the following error to
occur:
ERROR 30 S/3X FILE(S) NOT FOUND
Remove any periods found in file names before attempting to transfer on
the AS/400. It should be noted that periods are allowed in files
transferred on the IBM System/36.

longer manufactured, no fixes are planned for this problem.
2. When installing Netware/386 on an AST Premium/386C, the motherboard
must be equipped with the -007 or above keyboard controller chip.
This chip is socketed at location U103 on the motherboard and is
identified with AST part number 107210-007. If this chip has a part
number of 107210-005 or below, Netware/386 will not run.
To obtain the correct keyboard controller chip revision, it is necessary to
install an AST Premium/386-386C BIOS Upgrade Kit, AST P/N 500702-001.

XFORMER/286 COMPATIBILITY ISSUES
AST EPM Product Marketing has considered all aspects of the following
compatibility issues regarding the Xformer/286 (part number 202204-XXX).
They have determined that AST will not attempt to establish the cause of the
incompatibilities.
These issues are:
- A conflict exists between the AST Rampage/286 card and an SMC Arcnet
PC250 card when the two are installed together in the Xformer/286. The
system intermittently re-boots when a DOS command is entered from the
keyboard. (PR#B33016)
- The Xformer/286 intermittently loses setup information stored in CMOS.
(PR#B33020)
- After a "warm boot" the <UP> and <DOWN> arrow keys (on an enhanced

INSTALLING AST 3G PRODUCTS WITH OS/2 EXTENDED EDITION
To insure compatibility with AST OS/2 Extended Edition 1.10, the AST 3G Plus
(part number 202104-XXX) must have BIOS revision level "F" or above
installed. The BIOS chip is located at U29. The revision level can be read
directly from the label on the BIOS chip.
Likewise, the AST 3G Plus II adapter (part number 202161-XXX) must have BIOS
revision "D" or above installed. The BIOS chip on the 3G Plus II is located
at U10.
In addition, Hercules emulation must be disabled for both of the above video
adapters when used with OS/2 Extended Edition. Hercules emulation generates
non-maskable interrupts which conflict with OS/2 initialization. Consult the
respective 3G adapter User's manual for the method of disabling Hercules
emulation.

AST DOS 3.3 AND IBM PC SUPPORT INSTALL UTILITY
The IBM AS/400 PC Support Install utility Release 1.02 Level 00 does not work
on a PC which uses MS-DOS instead of PC-DOS. The following is a method that
may be used to install the AS/400 PC Support software on an MS-DOS system
that has an AT-style bus and uses the IBM 5250 Enhanced Adapter card. If
using an Enhanced AST-5251/11, Enhanced AST-5251/11 Plus or Enhanced AST-
5251/11A Plus Adapter card, use the AST Twinax Adapter Handler for AS/400 PC
Support and its documentation.
This method assumes that the user is using two 360k diskettes on which to
install the PC Support system. If the user is using a hard disk or diskettes
with higher capacity, all of the files may be put on the single disk in a
single subdirectory.
1. FORMAT THE DISKS:
Format the first working disk and install the operating system on it.
Label the disk AS/400 PC SUPPORT, FIRST WORKING DISK. An example of the
command to use for formatting:
format a: /s
Format the second disk without the operating system. Label the disk
AS/400 PC SUPPORT, SECOND WORKING DISK. An example of the command to use
for formatting:
format a:
Copy COMMAND.COM onto the second disk root directory.
2. CREATE CONFIG.SYS:
Using a text editor such as edlin, create a CONFIG.SYS file in the root
directory on the first working disk which contains the following lines:
device=\pcs\eimpcs.sys
device=\pcs\ecyddx.sys
device=\pcs\fsdd.sys
files=15
3. CREATE PCS SUBDIRECTORY:
On each working disk, create a PCS subdirectory using the command:
mkdir \PCS
4. CREATE CONFIG.PCS:
This file is used by the PC Support system to get information on the
"name" of the PC, the "name" of the host AS/400 and the station address
that should be used to communicate to the AS/400. The CONFIG.PCS file
should be created with a text editor and placed in the PCS subdirectory
of the second working disk. Typical contents are:
RTYP 5250
RTLN APPN.Pcname
EMLI Hostname,2
Pcname is the name of the PC you are using. Each PC connected to the
AS/400 via PC Support should have a different name. Hostname is the name
that was given to the host AS/400 when setting up the system. The number
2 indicates station address 2 is to be used to connect to the AS/400.
This number ranges from 0 to 6 and should be unique for each station on a
single twinax cable.
5. CREATE PCS.BAT FILE:
This batch file is used to start the AS/400 PC Support system. Using a
text editor create a pcs.bat file on the second working disk in the root
directory which contains the following lines:
[d:]* \PCS\E5250AH
[d:]* \PCS\STARTRTR \PCS\CONFIG.PCS
[d:]* \PCS\FSPC ASSIGN I: QIWSFLR
I:PCSUPDT I:\ \PCS
I:STARTMSG \PCS\CONFIG.PCS
I:VPRT
I:WSF /T
IF ERRORLEVEL 20 GOTO DONE
IF NOT ERRORLEVEL 10 GOTO WORKSTRT
I:STARTWSF 1
:WORKSTRT
I:PCO \PCS\CONFIG.PCS
:DONE
* Drive letter should designate drive where PCS subdirectory exists.
This batch file may be customized to start only those features of PC
Support that are desired.
6. COPY THE FILES FROM THE IBM DISTRIBUTION DISKS TO WORKING DISKS:
Copy the files from the IBM Distribution Disks to the subdirectory \PCS
on the working disks using the DOS copy command. For example:
copy a:eimpcs.sys b:\pcs\eimpcs.sys
From IBM Distribution Disk 1 to working disk 1 subdirectory \PCS copy:
EIMPCS.SYS
ECYDDX.SYS
FSDD.SYS
From IBM Distribution Disk 1 to working disk 2 subdirectory \PCS copy:
E5250AH.COM
FSPC.EXE
FSPC.HLP
XXRTRS.MRI
From IBM Distribution Disk 2 to working disk 2 subdirectory \PCS copy:
STARTRTR.EXE
E5250RTR.EXE
STOPRTR.EXE
7. REBOOT USING FIRST WORKING DISK:
Insert the first working disk in drive A and reboot your computer.
8. START PC SUPPORT:
Insert the second working disk in the default drive or set the default
drive to the drive which contains the second working disk. Type PCS to
invoke the PCS.BAT batch file and start PC Support.
Steps 7 and 8 may now be repeated to run AS/400 PC Support at future
times.

cannot access expanded memory.
- A conflict between REMM.SYS and a NEC GB-1 video adapter. Data errors
occur while REMM.SYS is initializing memory if both are installed in
the system.
- In a system which has a Hercules Plus card installed, WordPerfect does
not work correctly when REMM.SYS is present. The symptom exhibited is
that there is no cursor present on the screen when WordPerfect is
executed.
- A word processing program from SAMNA does not operate when REMM.SYS is
installed. The system locks up as the word processor is executed.
- With a Video Seven "VRAM" VGA adapter installed in the system, REMM.SYS
would generate the error message "NO Logical Memory Pages Found", then
abort.
NOTE: The Video Seven adapter runs in 16 bit mode, so the parameter
"/M=5F" should be added to the REMM.SYS command line in the
CONFIG.SYS file.

CONFIGURING FLOPPY DRIVES FOR AST SYSTEMS
To insure proper installation of a floppy drive into an AST computer system,
make sure the following conditions are met. The AST diskette drive
specification calls for "frame" ground to be connected to "logic" ground.
On many floppy drives this is accomplished by the correct placement of a
jumper on the drive's control electronics printed circuit board. Refer to
the instructions included with the drive to verify correct placement of the
grounding jumper.
In addition, the grounding strap from the power supply should be attached to
the drive's metal frame during installation. It should be noted that it may
be necessary to move the ground strap from it's normal position on the
Premium computer's chassis to a position where the ground connection on the
floppy drive frame can be accessed.

RUNNING COMPATIBILITY TESTS ON THE VGA PLUS
The IBM VGA standard supports two methods of addressing monochrome and color
displays:
- The VGA included on PS/2 systems allows software to address both
monochrome and color monitors at the same time with no restrictions
(colors in monochrome appear as shades of gray).
- The VGA adapter for AT type systems allows software to address either
color monitors or monochrome monitors, but not both.
The AST VGA Plus adapter is compatible with the VGA standard for the IBM AT
adapter. This means that software used with the VGA Plus will only address a
color display in color mode or a monochrome display in monochrome mode.
Switching between display modes is accomplished through the use of the
ASTVGA.EXE utility included with the VGA Plus utilities.
The adapter, by design, will not pass diagnostics written to test VGA
monochrome modes while the adapter is in VGA color mode. In particular,
tests from "PC Magazine" issue commands which are meant to test a PS/2 type
adapter and will fail on an adapter which follows the IBM AT adapter
standard. This is normal operation for any VGA adapter which follows the IBM
AT VGA adapter standard.
Some compatibility tests may also fail because of a hardware conflict. The
IBM AT VGA adapter supports the use of hardware interrupt IRQ2. However, the
AST VGA Plus adapter does not. The VGA Plus will fail tests such as one from
"PC Tech Journal" (test 13) which attempts to use IRQ2.

AST 5250 GATEWAY COMPATIBILITY ISSUES
Data Comm Product Marketing has considered all aspects of the following
compatibility issues relating to the AST 5250 Gateway product (part number
500399-001). They have made the determination that these issues will not be
resolved for this product.
These issues are as follows:
- The Gateway software will not function correctly when used on a DCA 10
Net LAN. The master and one slave will operate as a Gateway master and
slave. However, when a third node on the LAN tries to access one of
these two (e.g., a workstation accessing a server), then all three
systems lock up, requiring a cold boot of all the systems. (PR#A41040)
- Under Novell Netware version 2.12 software, IBM Token Ring boards
exhibit failures while running Gateway emulation. Any of the slaves on
the gateway will intermittently lock up or lose communication to the
master PC. (PR#A41044)
- When running under Gateway emulation, a print job sent to a printer
attached to a server using the Novell "CAPTURE" command does not print
correctly. Print data is shifted 3 or 4 columns in from the left
margin. (PR#A41051)
- Under a configuration where the slaves are communicating with the
master remotely via G-Remote Bridge (from Gateway Communications), the
response time for communication between slaves and master is very slow.
(PR#A41052)
- The 5250 Gateway does not support an environment which uses IBM Token
Ring cards running with Novell Netware 286 (all versions). When
operating under this type of environment, the slaves will lose
communication with the Gateway master, and require a reset to continue
the session. (PR#A41023)

INCOMPATIBLE DRAMS FOR RAMPAGEPLUS/286
Memory errors in a system which can be attributed to a RampagePlus/286 (part
number 202349-001) being present may actually be caused by the use of certain
manufacturers DRAM chips on the SIMMS present on the board.
SIMMS which are used to upgrade memory on the RampagePlus/286 have AST part
numbers 202279-002, 202280-002, and 202320-002. The DRAM chips which are
incompatible with the RampagePlus/286 are manufactured by Motorola and
Toshiba. The memory chips are of the 256KX4 type (three IC's present on the
SIMMS).
If memory errors or system lock-ups are being experienced, remove all SIMMS
containing these DRAM chips and substitute with other SIMMS. Other
manufacturers DRAM chips approved for the RampagePlus/286 are:
Mitsubishi M5M44256AP-10

AUTOSENSING OPERATION OF THE VGA PLUS
When the AST VGA Plus (part number 202262-003) is configured to operate in 16
bit mode (switch position "two" = ON) the entire memory address range from
C0000h to DFFFFh is in 16 bit mode for all system memory accesses. This is
due to the design of the IBM AT standard I/O bus. This means that an 8 bit
adapter which is configured to reside in this region will not be recognized
by the system.
Version 3.0 of the VGA Plus BIOS (part numbers 107000-682 and 107000-683) has
the ability to detect the standard IBM ROM signature "AA 55". If, when the
system is being initialized, the VGA BIOS detects this signature anywhere in
the 128K range where it resides, the VGA Plus will switch back to eight bit
operation to avoid conflicts.
The BIOS cannot detect the presence of RAM (e.g., shared memory) on an
adapter, however. In order for adapters which have this type of memory
(e.g., IBM Token Ring II adapters) to be configured to operate in this
address range, the VGA Plus has to be manually switched back to 8 bit
operation (switch position "two" = OFF) to avoid conflicts.

AST SHADOW BIOS MEMORY ADDRESSES
The following information provides two methods of determining which memory
range is used to shadow the system and video BIOS on AST computers equipped
with the Shadow feature. In addition to copying the system BIOS, AST Shadow
BIOS also has the option of copying the video BIOS. However, the video
adapter must be an AST VGA adapter or on-board VGA. The memory range used to
shadow the BIOS is based on the CPU type and system architecture. The memory
locations on earlier Premium systems differ from those currently
manufactured.
To determine which memory locations are used by Shadow BIOS, it is necessary
to identify the system's CPU type either by the part number of the processor
board or using the DOS DEBUG program.
Listed below are the steps to identify the CPU using DEBUG and which memory
locations that system uses for Shadow BIOS. Also included are processor
board part numbers as an alternative to running the DEBUG program.
DEBUG
At the DOS prompt, type: DEBUG and press the <enter> key. <Enter> is a
prompt to press the "enter" key. At the DEBUG prompt "-", type lines 1 and
2.
Line 1. -OE0 7 <Enter>
Line 2. -IE1 <Enter>
Line 3. -nn
Note: The number displayed on the third line identifies the CPU type.
If this value is a number between 12 and 18, Shadow BIOS uses the
memory locations shown in Method #2. Any other value identifies
the use of memory locations shown in Method #1. Enter Line 4 to
leave DEBUG.
Line 4. -q <Enter>
METHOD #1
When this method is used, the system BIOS uses a 64KB block at F0000-FFFFF.
However, when the system BIOS is shadowed, the E0000-EFFFF range is also
reserved whether the video BIOS is shadowed or not. If the video BIOS is
shadowed it resides in a 32KB block at E0000-E7FFF and the remaining 32KB of
that block is reserved.

PREMIUM 486/25 - NOVELL AND IBM TOKEN RING CARDS
Problems have been reported with IBM Token Ring Adapter cards (full length, 8
bit) and Premium 486/25 systems with cache enabled when loading Novell's
IPX.COM. The Token Ring Adapter card fails initialization when executing the
IPX.COM file.
The cause of the problem has been isolated to a software timing loop that
executes too fast for the Token Ring Adapter board to complete its
initialization before the driver times out and produces the error message.
The cause of the problem is the IBM Token Ring Adapters inability to
initialize fast enough on high performance systems such as the Premium
486/25.
The following options are available to customers experiencing the above
problem:
1. Disable and enable the cache using AST's SPEED.COM program prior to
executing IPX.COM by entering the following commands (in the order they
appear) at the DOS prompt:
> SPEED CACHE=DISABLE
> IPX.COM
> NETx
> SPEED CACHE=ENABLE
2. An alternate solution is to update the IBM Token Ring card to a short
card (IBM part number 25f98XX) or a 16/4 (IBM part number 25f73XX) card.
Customer should contact their IBM Dealer for information regarding these
cards.

MULTIPLE IPX VERSIONS AND 5250 GATEWAY
When linking multiple file servers and operating systems, (particularly
Novell), the following problems may occur when trying to link workstations to
a gateway:
- Error message "unable to find master gateway".
- With sessions connected, "hang-up" or loss of connection to the
gateway may occur.
The problems are caused by the various versions of IPX that use different
methods of addressing nodes and sending data packets. There are significant
differences between IPX versions 2.XX and 3.XX.
To optimize performance and reliability, common versions of IPX must be used
on all nodes.

NEW 386SX/16 PROCESSOR BOARD
The following information summarizes a compatibility problem with the new
386SX/16 processor board (part number 202380-001) and Cupid motherboards.
This new board replaces the original 386SX/16 processor board (part number
202337-001) and will be shipped with the Cupid enhanced motherboard in all
Premium 386SX/16 systems.
PROBLEM:
The new 386SX/16 processor board (part number 202380-001) is not compatible
with common Cupid motherboards using BIOS v1.01. System lock-ups occur when
attempting to change the processor speed. The problem occurs when using
either the keyboard method <Ctrl> <Alt> <Up Arrow> or the SPEED.COM program.
Lock-ups also occur during the processor speed change test when running the
confidence tests.
RESOLUTION:
In order to resolve the problem, a BIOS upgrade (from version 1.10 to 1.20)
on the Cupid motherboard is necessary. This can be accomplished by using a
Cupid BIOS upgrade kit (part number 500775-001).
Listed below are the part numbers for the motherboards which require BIOS
upgrades:

VGA MODES SUPPORTED ON AST VGA PRODUCTS
VGA is defined by IBM as a set of display modes up to and including 640 x 480
resolution in 16 colors. "Super" VGA is a super set of VGA, defined by the
Video Electronics Standard Association (VESA) to be 800 x 600 resolution, 16
colors.
Other display modes are also called "Super" VGA or "Extended Mode" VGA,
depending on the manufacturer of the VGA hardware. These modes do not fall
under the above definition of "Super" VGA, even though they are sometimes
referred to as such.
AST VGA products (VGA Plus adapter and embedded VGA) support Super VGA as
defined in the first paragraph above, plus other high resolution modes. The
following table summarizes the resolutions and color combinations supported

RAMPAGEPLUS/286 AND ZENITH COMPUTERS
The RampagePlus/286 (both part numbers 202247-XXX and 202349-XXX)
does not operate reliably when installed in Zenith 80286-based computer
systems. Parity errors are generated by memory installed on the Rampage
board, either at the time of system boot up, or during the running of
an application.
This incompatibility exists as a result of the method by which the Zenith
system performs memory addressing. The Zenith implementation of memory
read/write cycles does not allow enough time for data from the Rampage memory
to be stable, thus the parity errors.
Any hardware change made to the RampagePlus/286 to resolve this
incompatibility would prevent the board from operating in AST, IBM or IBM-
compatible systems. Therefore, Zenith should be contacted directly for a
resolution.

BRAVO/386SX - SEAGATE 157A
Bravo/386SX systems which have the AST part number 500801-XXX may have
Seagate ST-157A hard drives installed. The AST part number for this drive is
230119-001. These drives are 40MB IDE type drives, which are configured as
drive type "17" in the Bravo's CMOS setup.
The following items are important for proper operation of the system but are
not documented by AST:
1. These drives are configured to operate as the main hard drive in a
system. They are not to be configured, and will not operate as a
"slave" to another hard drive which is installed as a "master" in this
system.
2. There is a jumper block on the control PCB labeled "J2". It is located
at the left rear of the board when viewing the drive from it's front
panel. It is comprised of three pairs of 2-pin headers labeled "1"
through "6". For use in this system the pair labeled "1" and "2" must
have a jumper installed. This configures the drive for a single drive
system. Also, the pair labeled "5" and "6" must have a jumper
installed. This enables the "external LED", sending the drive
activity signal to the front panel of the Bravo/386SX.

PREMIUM 386/16 WITH MATH CO-PROCESSOR
Erratic operation may occur when using a math co-processor in the Premium
386/16. This condition was first observed when running AutoCAD Release 9 and
10. The system may lock up when running software that uses the math co-
processor after the system has warmed up (anywhere from immediately to 30
minutes). The failure is encountered consistently after re-booting until the
system has been shut off and allowed to cool down.
The cause of the problem is a contention with the 87BUSY* signal from the
math co-processor. The contention situation is eliminated by lifting or
cutting pin 16 on the chip at location U34 on the Premium 386/16 processor
board (AST Part Number 202323-001). Denoted after the part number is a
revision letter (i.e., 202323-001C). Use the following list to determine the
appropriate action to be taken:
Revision Action
C or earlier You should return the board to AST for modification.
D Modification may be performed by an AST Authorized
Service Center.
E or later Modification has already been implemented, and no action
is required.
WARNING: This operation is meant to be performed on Premium 386/16 processor
boards only (AST Part Number 202323-001), NOT on Premium 386SX/16 or
386SX/20 processor boards. All modifications should be performed by

GUIDELINES FOR USING NOVELL'S COMPSURF UTILITY
The following are some general guidelines that should be followed when using
Novell's compsurf utility:
NEVER use the format option in COMPSURF when:
- Using a SCSI drive.
- Using a drive over 1024 cylinders.
- Using a WD1007A-XXX hard drive controller.
- Hard drive manufacturer forbids it.
To successfully prepare a hard drive (over 1024 cylinders) for Novell, do
the following:
- Set drive type in CMOS per manufacturers recommendations.
- Low-level format using the manufacturers format utility (i.e.,
HDFORMAT for an AST drive).
- If the drive requires the Novell compsurf "stamp", run compsurf but DO
NOT take the format option.
- As soon as the compsurf utility starts, it will check track 0.
Immediately after the track 0 test is completed (usually within 45
seconds), hit the ALT + F10 keys twice. This should stop the compsurf
utility and "stamp" the drive.

When installing a Paradise 8514/A video card in a Premium 386SX-16 system,
certain errors may be experienced. These errors are:
- When the Premium 386SX-16 computer is "powered on", the system will go
through post test and, at the memory count, the monitor will go blank
and the system will give one long beep.
- The second error will occur while running the WDAI.EXE program. This
program initializes the video adapter. However, during the
initialization of the video card, WDAI.EXE does not recognize that the
Paradise 8514/A video card is installed in the Premium 386SX-16
computer system.
Customers should verify what Premium 386SX-16 processor board is in the
system by removing the cover. If the Premium 386SX-16 processor board has
AST's part number 202337-001, it needs to be replaced with AST's part number
202380-001. Customers who are experiencing the above problem should contact
an AST Authorized Service Center for replacement.

PREMIUM EXEC BATTERY MANAGEMENT CONTROLLER
Under certain circumstances, some Premium Exec 386SX/20 computers may exhibit
one or more of the following problems when connected to the AC adapter after
the battery has been completely discharged:
- Battery will not charge completely.
- Over charge of battery.
- Erroneous battery charge level indicators (LED) when connected to the
AC Adapter.
- Low battery alarm when connected to the AC Adapter.
- Intermittent loss of display when booting.
To resolve these problems, it is necessary to reset the Battery Management
Controller (BMC) chip. To accomplish this, follow the steps listed below:
1. Power off the Premium Exec.
2. Disconnect the AC Adapter from the Premium Exec.
3. Wait approximately 10 to 15 seconds, reconnect the AC Adapter to the
Premium Exec.
4. Power the Premium Exec back on.
If this does not resolve the problem, the system may have a defective BMC
chip. Contact AST or your nearest AST Authorized Service Center to have this
chip replaced (re: Field Change Notice #0058).

PREMIUM EXEC SUSPEND/RESUME AND PROTECTED MODE
The Premium Exec 386SX Suspend/Resume feature will not function when running
software that requires Protected Mode operation. This includes applications,
such as Windows 3.0 and extended memory managers (i.e., QEMM and ASTEMM).
This problem is caused by the 386SX microprocessor's requirement for
applications or memory managers using extended memory to run in protected mode
only. All 386SX "notebook" type computers, equipped with a Suspend/Resume
feature, exhibit this anomaly and to date, there are no known resolutions.

AST PREMIUM SYSTEMS WITH BUILT-IN MOUSE PORTS AND ADIC'S DCB
When installing two ADIC DCB controller cards, Channel 1 and Channel 2 in an
AST computer, errors will occur on the second DCB controller which is Channel
2, (i.e., Channel 2 will fail to initialize under Novell Netware environment
and will also fail ADIC diagnostics).
The problem lies with IRQ12, which supports the PS/2 mouse port. ADIC's DCB
controller card Channel 2 is hard wired, this cannot be changed. (IRQ12 is
accepted as Industry Standard for PS/2 mouse port). ADIC's Technical Support
recommends that the customer using the DCB Channel 2, switch and use DCB
controller Channel 3 which uses IRQ10. Customers experiencing the above
problem should contact ADIC's Technical Support to exchange DCB controller
cards.

SUN RIVER CARD AND AST PREMIUM/386-33TE
When using the Sun River Fiber Optics Host adapter card, model HA-40, with
the AST Premium/386-33TE with greater than 15MB total memory the following
error message will be displayed at boot time:
"Sun River card not found".
The above error message will only occur when RAM is installed in the 16MB
space. The Sun River card uses the 16MB space for I/O addressing their card,
which conflicts with the processor memory addressing.
If this problem occurs, configure the system with 14MB or less of memory.
Marketing has determined that this problem will not be fixed.

NOVELL 386 WITH AST DESK TOP AND TOWER SYSTEMS
The following problems are occurring with AST Cupid desktop and Cupid Tower
systems configured with more than 16MB of RAM with Novell Netware 386 version
3.10:
- System will lock up after attempting to mount the drives
- Intermittent memory parity errors occur
- Intermittent lock-ups occur
The above problems occur because the Novell operating system has not been
made aware of any memory above 16MB. This problem can be resolved by
registering the memory with the Novell operating system so that it knows how
to access the memory. To accomplish this, edit the AUTOEXEC.NCF file within
the Novell install option as follows:
REGISTER MEMORY [START(hex)] [LENGTH(hex)].
Using the chart below replace the [START(hex)] and [LENGTH(hex)] with the
appropriate parameter.

THE SUPER VGA MONITOR WITH AST VGA ADAPTERS
In January of 1991, the "dot clock" frequency of the AST Super VGA monitor
(part number 500783-XXX) became 36 megahertz in order to comply with industry
standards. This is designated by the characters "36MHZ" on the back of the

PREMIUM II SYSTEM BIOS AUTOSENSE FEATURE
The Premium II BIOS (version 2.0 and above, AST part numbers 237826-001A and
237827-001A) supports a feature known as "Autosense". This feature allows
the BIOS to automatically sense, and use, optimized parameters which take
advantage of the full capacity of IDE type hard drives.
Prior to this feature, the parameters for a particular drive had been
determined by entering a discrete value (e.g. "17") in SETUP. This value had
to operate with drives from several vendors, so these parameters were not
always optimal for a particular drive.
This means that the same drive configured by these two methods will have two
different sets of parameters, particularly the number of cylinders.
Therefore, a drive which has been partitioned and formatted under a discrete
drive type may have to be re-partitioned and re-formatted when configured by
the autosense feature. Make sure the following steps are taken before using
autosense to configure a drive:
- Save the data currently on the drive. Save only files and directories,
not partition information.
- Run SETUP and choose "AUTO" for drive type. A set of parameters will
be returned for the installed drive. Save the configuration and exit
SETUP.
- Re-partition and re-format the drive under the new configuration, and
restore the original data.
Note: The Conner CP-3000 40MB drive (AST part number 230092-040) cannot be
configured via the autosense feature. This drive must be manually
configured as type "17" in the SETUP program.

EXCESSIVE HEAT IN TOWER EISA SYSTEMS
Tower EISA systems with 80486 processor boards installed exhibit intermittent
failures under certain operating environments. Normally under these
conditions there are one or more Host Bus Adapters (HBA's) or multiple
network interface cards installed in the system as well as the processor
card. The failures exhibited are:
- Complete system halts, forcing a reset of the system,
- Error messages generated by the operating system in use.
The cause of these intermittent failures has been proven to be caused by
excessive heat buildup in the tower enclosure due to improper placement or
installation of the enclosure itself. To insure proper operation of Tower
EISA systems in all operating environments, the following guidelines must be
met:
1. Proper ventilation must be supplied for the Tower enclosure
2. Ambient air temperature must be within the specifications stated in
the Tower User's Manual.
3. All system covers, including drive bay covers, must be installed
while the system is operating. These enclosures are designed for
optimal air flow with the covers in place.
4. The processor board installed in the system must be a particular
revision level. The processor boards listed below have a vented
bracket (AST part number 200412-001) installed which aids air flow.
Processor Board Part Number Revision

PREMIUM II ILLEGAL CMOS VALUES
Premium II systems, while running Power On Self Test (POST), may display the
status of cache memory as "Disabled", but CMOS SETUP displays cache as
"Enabled". These contrary indications are caused by two bits in CMOS memory
being set to illegal values. Systems affected are those with version 2.00
BIOS (part numbers 237826-001 A and 237827-001 A) installed.
The illegal setting can be verified by entering SETUP and using the PAGE DOWN
key (instead of using the TAB key) to view the status of "Cache Memory".
With the illegal values set, this field will show that neither "Enable" or
"Disable" has actually been selected.
To insure that the cache feature is properly enabled and functioning, perform
the following steps:
1. Enter the SETUP program as described in the Premium II User's Manual.
2. TAB down to the "Cache Memory" field and use the ARROW keys to choose
"Disable".
3. TAB to the next field down, then SHIFT-TAB immediately back to the
"Cache Memory" field and choose "Enable".
4. Save the new configuration upon exiting the SETUP program.
The system will boot and display "TESTING CACHE ......ENABLED" during POST,
and the cache feature will function normally.

SCO UNIX BOOT FAILURE WITH MEMORY EXPANSION BOARD
PROBLEM: Under SCO UNIX 3.2 version 2.0, system will hang
intermittently during boot if memory expansion board is
present, AST part number 202387-001.
AFFECTED
SYSTEM BOARDS: All system boards with the following part numbers:
202356-004 and 202360-001
CAUSE: During UNIX installation the software will check for known
devices and will activate a driver for that device. UNIX
mistakenly identifies a device that is not present, and
activates a driver for it. This causes the system to hang,
with the following error message:
WDHA-OUT: command byte 01 rejected
WDHA-OUT: command byte 07 rejected
SOLUTION: The new release of SCO UNIX 3.2 version 3.0 resolves this
problem and is scheduled to be released by SCO in July,
1991.
NOTE: A temporary solution would be to slow the system down
during the boot process, and resume normal speed after
completion of boot sequence, which would be the login
prompt. This can be accomplished by using the <CTRL>
<ALT> <DOWN ARROW> and <CTRL> <ALT> <UP ARROW>
sequence. For further information on speed commands,

Western Digital are working together on a software driver
that will support Western Digital's Elite 16 combo card.
WORKAROUND: Banyan Vines and Western Digital Technical Support, both
agree that the NDS software driver should be selected when
installing the network card. Also, the AST VGA Plus must be
forced to 8-bit mode. If the AST VGA Plus is set for 16-bit
mode the system will not boot. The reason for this error is
the software drivers that are supported in Banyan Vines

AST 5251/12 REMOTE GATEWAY INSTALLATION
PURPOSE: To remotely attach multiple network nodes to an IBM mini (IBM
System 34, 36, 38 and AS/400) while only installing one
emulation card.
REASON: Cost effective way to have multiple nodes access emulation
while only having one emulation card and additional gateway
software.
HARDWARE
REQUIREMENTS: AST 5251/12 (CC-432 Adapter) Emulation Package. A NETBIOS
Compatible Local Area Network already installed and
operational. Synchronous Modems (NOT HAYES COMPATIBLE)
SOFTWARE
REQUIREMENTS: 5251/12 Emulation Version 4.30 (part number 910408-001,
910408-002 and 910408-003). 5250 Gateway Option Version 4.30
(part number 910411-001)
NOTE: Versions of both 5251/12 Emulation Software and 5250
Gateway Software may be updated in the future.
HARDWARE
SET UP: AST 5251/12 Adapter IRQ=2; I/O=300-30F (DEFAULT)
The above settings are factory default. If a conflict arises
with other hardware in the PC, the user should consult with
the conflicting hardware's reference manual for the settings
and change the AST hardware and software, or vice versa, in
order to resolve the conflict.
For installing and connecting the two Synchronous Modems
please refer to the Modem Manual, the AST 5251/12 User's
Manual (part number 000427-001A) and the AST CC-432 User's
Manual (part number 000140-001E) for more information.
Note: This document assumes that the user is qualified to
establish a successful Modem connection with the IBM
Host.
INSTALLATION: The Master PC contains the AST CC-432 Synchronous
Communications Adapter, the 5251/12 Emulation program, the
5250GATE.EXE program which is attached to the network. The
Slave PC contains the KERNELGW.EXE program which is attached
to the network.
A. MASTER PC CONFIGURATION
1. Type the following at the DOS prompt for the directory that
contains the AST 5251/12 Emulation Software:
C:\AST> CFG5251 [Enter]
This assumes that the subdirectory name is AST and is located on
the C: Drive.
2. Answer (n)o for MASTER CLUSTER.
3. Answer (n)o for ASYNC DIAL UP.
4. Answer (y)es for MASTER GATEWAY.
5. Answer (n)o for QUICK START.
6. From the AST 5251/12 Configuration Program (CFG5251.EXE) menu,
highlight EDIT and press [Enter].
7. Answer (y)es to modify the configuration file, AST5251.CFG.
8. The EDIT 5250 CONFIGURATION menu will appear with the
following options:
HARDWARE KEYBOARD STATION SECURITY VDISK CUSTOMIZE
CLUSTER GATEWAY QUIT
9. Highlight HARDWARE and press [Enter]. These options will
appear:
HARDWARE DSP_ADAPTER QUIT
10. Select HARDWARE again. This is the HARDWARE selection. All
the options in this section pertain to how the emulation
adapter and communication line is configured.
IRQ BPS NRZI I/O_ADR TRACE SDLC QUIT
11. The BPS, NRZI, TRACE and SDLC options are not set from AST
(default factory settings). The user must set each option
accordingly.
12. The BPS option pertains to the baud rate of the Synchronous
Modem that the user is connecting to the AST CC-432 (AST
5251/12) Communications Adapter. Under this option the
following list will appear and the user should select the
correct rate:
1200 2400 3600 4800 6000 7200 8000 9600 QUIT
13. The NRZI option is host (IBM System 34, 36, 38 or AS/400)
controlled. This is IBM's error correction detection system.
It is either ON or OFF. The user must verify this parameter
with the host's system operator.
14. Under the TRACE option these options will be displayed:
NONE SNA SDLC QUIT
Note: It is recommended that the TRACE option be used as this
is a good trouble shooting tool. With this option
selected the user will observe a fixed set of numbers
followed by incremental numbers on the bottom left and
right hand corners of the display during emulation.
The numbers on the left bottom corner indicate that the
AST package is receiving data from the Modem and the
numbers on the right bottom corner indicate that the
AST adapter is transmitting data to the Modem.
If there are no numbers at either corner then it
indicates that the Modem is not communicating with the
AST CC-432 Adapter. Several probable causes for this
occurring are as follows:
A. Bad or wrong type of cable connecting the Modem to the AST
CC-432 Adapter. User could be using a standard
asynchronous null Modem RS-232 cable that does not have
pin 15 (transmit clock) and pin 17 (receive clock)
connected.
B. IRQ or I/O_ADR conflict between other hardware in the PC
with the AST Adapters.
C. Memory resident (TSR) programs such as; fixed disk
organizers, menu programs, keyboard macro programs, and
etc., that may conflict with the AST 5251/12 Software.
D. The NRZI option does not match between the host and AST
5251/12 Emulation.
15. Highlight SDLC and press [Enter]. This is the controller
station address configured at the host (IBM System 34, 36, 38
or AS/400) site. The user must verify this parameter with the
host's system operator. It is a hexidecimal value and ranges
from 01 through FE. Enter the appropriate value and press
[Enter].
16. Press the ESC key and then highlight DSP_ADAPTER and press
[Enter]. Highlight DSP_ADAPTER on the next screen and press
[Enter]. Next highlight the type of display adapter you are
using and press [Enter]. Example: "Color".
17. Press ESC until you return to the EDIT 5250 CONFIGURATION
menu. Highlight STATION and press [Enter], the following list
will appear:
0 2 3 4 5 6 7 8 9 QUIT
18. Station Address 0 will always be configured as a 5251/12
display type. This cannot be changed. Station Address 1 is
reserved for SNA and is not available. The address scheme for
the AST 5251/12 Station Addresses and the IBM Host Addresses
are as follows:
STATION option (AST) 0 2 3 4 5 6 7 8 9
Ports on IBM 0 1 2 3 4 5 6 7 8
Respectively for an IBM 5251/12 (what AST is emulating) remote
controller where all device codes are configured for
workstation address 0. Page 3-12 of the AST 5251/12 User's
Manual (AST part number 000427-001) displays this scheme in
more detail.
19. Highlight STATION Address 2 and press [Enter]. These options
will appear:
DISPLAY PRINTER CLUS_DISPLAY CLUS_PRINTER
GATE_DISPLAY GATE_PRINTER QUIT
20. Highlight GATE_DISPLAY and press [Enter].
21. Highlight 5251/11 (can also select 5291-1 or 5292-1 but will
use a 5251/11 for this example) and press [Enter]. Press the
ESC key when asked to "enter new session name for station
address 2". For this configuration, session names will not be
used.
22. Repeat steps 19 through 21 as many times as needed to
configure all the station addresses that will be given to the
Gateway. In this example a total of seven sessions are
configured. Make sure that the number of sessions configured
on the AST 5251/12 software matches the number that the IBM
host will be allocating to the Gateway.
23. Highlight the other addresses and select the appropriate
DEVICE TYPE and press [Enter]. Configure the station
addresses as follow:
ADDRESS 0 - 5251/12 DISPLAY IBM-API: OFF
ADDRESS 2 - 5251-1* GATE DISPLAY (NO SESSION NAME)
ADDRESS 3 - 5251-1* GATE DISPLAY (NO SESSION NAME)
ADDRESS 4 - 5251-1* GATE DISPLAY (NO SESSION NAME)
ADDRESS 5 - 5251-1* GATE DISPLAY (NO SESSION NAME)
ADDRESS 6 - 5251-1* GATE DISPLAY (NO SESSION NAME)
ADDRESS 7 - 5251-1* GATE DISPLAY (NO SESSION NAME)
*The type of display can vary depending on what the host is
configured for. The other device types that can be emulated
by the AST 5251/12 software or the 5291-1 and the 5292-1.
Note: This sample is configured so the Slave PCs will be
assigned an address/session on a first-come first-serve
basis which is called "session bidding".
24. When all the required addresses are selected press ESC until
you reach the AST 5250 CONFIGURATION PROGRAM menu. Now save
the MASTER/PASSTHROUGH configuration settings and exit to DOS.
25. Highlight SAVE and press [Enter].
26. The program will ask "Save configuration file: AST5251.CFG
(Y/N)?" Respond "yes" and press [Enter].
This concludes the configuration of the MASTER PC.
B. SLAVE PC CONFIGURATION
You can use one configuration file for all the network node SLAVES
provided that all the Slaves have the same type of display. The
slave software when executed will look at the master configuration
software to see what gateway displays are available.
1. Type the following at the DOS prompt for the directory that
contains the AST 5250 Gateway Software:
C:\GATE\CFG5251G [Enter]
This assumes that the software is located in a subdirectory
named GATE which is on the C: Drive.
2. Answer (n)o for QUICK START
3. From the AST 5250 CONFIGURATION PROGRAM menu, highlight EDIT
and press [Enter].
4. Answer (y)es to modify the configuration file, AST5251G.CFG.
5. The EDIT 5250 CONFIGURATION menu will appear with the
following options:
HARDWARE KEYBOARD STATION SECURITY VDISK CUSTOMIZE
CLUSTER GATEWAY QUIT
6. Highlight HARDWARE and press [Enter]. Highlight DSP_ADAPTER
and press [Enter]. Highlight DSP_ADAPTER again and press
[Enter]. Select the appropriate display adapter for this
particular SLAVE PC (Mono or Color).
NOTE: If the Slaves on the network have various types of
displays (i.e., monochrome and color), different
configuration files (AST5251G.CFG) will need to be
created to match each type of display.
7. Press the ESC key until you return to the EDIT 5250
CONFIGURATION menu. Highlight STATION and press [Enter].
8. STATION ADDRESS 0 is already configured for you.
ADDRESS 0 - 5251/11* DISPLAY IBM-API: OFF
(NO SESSION NAME)
*The device type can also be a 5291-1 or a 5292-1.
For this setup you do not need to delete or reconfigure.
Address 0 on the MASTER PC is taken by the 5251/12 Controller
so this SLAVE PC configuration would then go to the next
available session on the MASTER PC which would be address 2.
Note: We are setting this up for "session bidding", therefore
we do not need to configure the exact station address
for the slave. When the slave software is executed, it

PREMIUM EXEC AND LCD BORDER COLOR
Customers have noticed different border colors on the Premium Exec 386SX/20.
These colors are blue and black and are only observed by looking at the edges
of the Liquid Crystal Display (LCD) on the Premium Exec 386SX/20.
AST's Portable Marketing department has concluded that this is not a problem.
All three (3) LCD's that AST sources for use in the Premium Exec have a
unique border color. The reason for the color difference is only possible to
note when looking at the edges of the LCD, since the color beyond the edges
is reversed out to white. Most importantly, AST has not compromised the
quality of the Premium Exec 386SX/20 in any way by using multiple LCD
sources.

PREMIUM II 486SX/20 AND LOTUS 123 RELEASE 3.1
SYMPTOM: Unable to input numeric values into the Lotus 3.1 worksheet.
The numeric values appear only as zeros while alphanumeric
values are fine.
PROBLEM: Lotus 3.1 recognizes that the system has a 80486 Processor and
assumes that there is a Math Coprocessor available. This is
true for the 80486DX Intel Chip but not for the 80486SX. When
a Math Coprocessor is present, Lotus passes on the tasks of
numeric calculations to the Math Coprocessor which is not
available in the Premium II 486SX/20 as a standard option.
This can be checked by accessing the Worksheet Status Menu
option which will show the system information such as;
Available memory, Processor type, Math Coprocessor type and
other Lotus configuration information.
SOLUTION: By typing "123 -s" at the Lotus 3.1 prompt the Premium II
486SX/20 system will be recognized as a 80386 system with no
Math Coprocessor, enabling Lotus to handle the numeric
calculations. The "-s" switch instructs Lotus that the
system has a 386 Processor with no Math Coprocessor instead of
a 486 Processor. This will allow the Premium II 486SX/20 to
be able to input numeric data.
Lotus is also aware of this issue and customers can contact
Lotus at (800) 343-5414 and order the Lotus 3.1 update which
resolves this problem. With this update the Lotus program
will no longer assume that the 80486 Processor has a built-in
Math Coprocessor and the "-s" parameter will no longer be
necessary.

SCO OPEN DESKTOP IN 800X600 VIDEO MODE
PROBLEM: When using the Open Desktop release 1.0 and 1.11 in SuperVGA
(800x600x16) mode, vertical bars and multiple horizontal images
are displayed on the screen. The 640x480 and 640x350 modes work
fine.
CAUSE: The "grafinfo" file for the video contains some additional
information which is only required for the AST VGA Plus card.
SYSTEMS
AFFECTED: All systems with integrated video.
SOLUTION: To fix this problem complete the following steps:
(Lines starting with the # sign indicate commands that should be
entered at the root prompt).
1) Bring the system down to single user mode (init 1).
2) # cd /usr/lib/grafinfo/paradise.
3) # cp vgaplus.xgi vgaplus.orig (you are saving the
file vgaplus.xgi as vgaplus.orig).
4) Edit the file vgaplus.xgi.
5) Search for, and remove the following two lines
from the file:
out (0x3CE,0x0B); out(0x3CF,0x44); / *256k 16 bit */
out (0x3CE,0x0C); out(0x3CF,0);
6) Save the file and exit you editor.
7) # mkdev graphics.
8) Select "update" from the main menu.
9) Choose the Paradise VGA Plus from the list of
Adapters.
10) Choose the VGA 800x600 16-color option from the
list of Modes.
11) Press return twice to accept the Default
configuration, and accept the current setting.
12) Choose "Quit" from the main menu, then "save".
(This will update the grafinfo database to reflect
the changes you have made to the file).
The system does not need to be re-booted, just go back to multiuser mode and
ODT will now work in 800x600 mode. This updated file will work correctly on
the regular VGA Plus board also.

AST's SVGA MONITOR AND OS/2 1.21
SYMPTOM: Various screen problems may occur with AST systems using the
800x600 resolution mode under AST OS/2 version 1.21 with the
AST SVGA monitor. Some of the problems experienced are as
follows:
Shaking of the screen.
Slight shift of the screen.
A line down the center of the screen.
A loss of the screen when switching between video modes.
PROBLEM: The current BVHVGA.DLL driver under AST OS/2 version 1.21
instructs the video chip on the AST system board to generate
an output of 34.4 kHz instead of the VESA (Video Electronics
Standard Association) specified horizontal frequency of 35.2
kHz for SVGA monitors. The AST SVGA monitors follow the VESA
specifications for the horizontal frequency.
SOLUTION: A driver called BVHVGA.DLL with the byte size of 37994 is
available on the AST BBS under the file name of OS2-VGA.ZIP
which is located in the file area called SYSTEMS. This driver
sets the video chip output to match the VESA specified SVGA
horizontal frequency of 35.2 kHz for the AST SVGA monitor.
This new driver will be incorporated in AST OS/2 version 1.3.

Problems may occur with the Premium Exec 386SX/20 and 386SX/25 when
attempting to use the Task Swapping feature under the MS-DOS 5.0 DOSSHELL.
When attempting to swap between tasks, the computer will beep and continue to
run without swapping. This problem does not occur when running AST's version
of MS-DOS 5.0.
The problem is caused by the MS-DOS 5.0 installation program installing a

AST 486 BASED SYSTEMS WITH ADAPTEC 1540 AND 1542B
PROBLEM: AST 486 based systems using an Adaptec 1540 and 1542B SCSI HBA
shows a significant loss of performance by Checkit and
Sprinrite. Data transfer rates are reduced by 33 percent when
compared to a Premium/386-33 or a Premium 386SX-16 system.
CAUSE: Adaptec's controller request for the bus are being held off
while the 486 completes code fetch sequences from Adaptec's
byte-wide BIOS ROM. This results in 16 accesses to the ROM
over the bus, because the 486 processor fetches 128 bits at a
time then releases the bus. The 386 processor fetches 32 bits
then releases the bus. Since the 486 processor holds Adaptec
controller off the bus longer during this access, the overall
performance is significantly reduced as compared to the 386
based system.
AFFECTED
SYSTEMS: AST 486 based systems
SOLUTION: It has been determined that this problem will not be fixed.
Customers experiencing this problem should use QEMM-386

BIOS SHADOWING IN AST SYSTEMS
This document presents information on the topic of BIOS shadowing.
Persistent misinformation and rumors abound on BIOS shadowing. If properly
informed most users should view shadowing as a positive and significant
performance enhancer rather than a feature to be avoided.
Performance:
System BIOS and video BIOS shadowing is done to improve performance. This is
done by executing the BIOS code out of RAM rather than ROM. A performance
gain is achieved by executing out of RAM because it has a much faster
response time than the ROM. The slower response time of the ROM acts as a
barrier to today's higher speed processors.
Shadowing Location:
During POST the system BIOS copies an image of itself as well as an image of
the video BIOS into RAM. The location where this image is copied depends on
the vendor's philosophies as well as hardware capabilities. The AST
philosophy is to follow the strategy of "in-place" shadowing. What in-place
shadowing means is that the system BIOS will be copied into RAM located at
F000:0 and the video BIOS will be copied into RAM located at C000:0. For
those familiar with the PC architecture, in-place shadowing locates the
shadowed BIOS at the same location as the ROM version (unshadowed BIOS).
Early in AST's systems history, the hardware was not able to support the in-
place shadowing strategy. The very early systems would shadow the system
BIOS at F000:0 but the video BIOS had to be shadowed at E000:0. Progress in
AST's hardware development made in-place shadowing possible for systems
starting in the latter part of 1989. The choice of shadowing in-place or not
is limited by hardware and is not a BIOS design issue.
Advantages of In-place:
Shadowing in-place has the significant advantage of conserving valuable upper
memory addresses. A typical unshadowed system will utilize a total of 96K
bytes of valuable address space between the 640K and 1M region. This is
allocated as 64K bytes at F000:0 for the system BIOS and 32K bytes at C000:0
for the VGA BIOS. The AST strategy of in-place shadowing utilizes exactly
96K bytes of this valuable address space when shadowing is activated. A
different shadowing strategy commonly utilizes 160K bytes of this address
space between 640K and 1M.
The chart below illustrates how the in-place shadowing strategy conserves
valuable upper memory addresses.
Upper Memory Address Utilization:
No Shadow In-Place Other Scheme
C0000-C7FFF VGA BIOS VGA BIOS VGA BIOS (ROM)
E0000-EFFFF not used not used VGA BIOS (Shadowed)
F0000-FFFFF system BIOS system BIOS system BIOS
total space 96K bytes 96K bytes 160K bytes
The second significant advantage of in-place shadowing is that it presents
the same characteristics as the typical unshadowed system. For programs which
"sniff" or search the 640K - 1M region, a system which has in-place shadowing
has the video BIOS and system BIOS in exactly the same locations as the
typical unshadowed system. There is no anomaly as in other shadowing
strategies which have a video BIOS located at C000:0 (the ROM image) as well
as at E000:0 (the shadow image).
Reserved Memory:
All current AST systems as well as all new AST designs have 128K bytes of
reserved memory set aside to support shadowing. All memory except this 128K
bytes is available to the user. The reserved memory is used as the shadow
RAM. There has been no attempt to design systems where only 96K is reserved
rather than 128K. Providing this extra 32K to the user would significantly
increase hardware costs.
There are a few exceptions to the 128K reserved memory rule. The Bravo
286/16 is an example of a system which gives reserved memory back to the
user. This extra 128K is available if shadowing is turned off in specific
memory configurations. Because of the costs and complications involved to
provide an extra 128K bytes of memory for the minority of users who wish to
disable shadowing, AST systems will continue with the 128K reserved memory
rule.
Write Protection:
Write protecting the shadowed BIOS is important as it prevents program bugs
or poorly designed programs from destroying the video or system BIOS images
in RAM. This issue affects AST as well as all system vendors. This write
protection attribute coupled with the in-place shadowing yields the perfect
shadowing scheme.
Systems with cache can present a wrinkle in write protecting the shadow RAM.
Until very recently, AST systems with cache did not provide the hardware
capability to write protect the video BIOS shadow area. Write protection of
the video BIOS shadow area was complicated by the fact that the cache was
caching the video BIOS addresses. (The system BIOS area has been write
protected as the cache does not cover the system BIOS addresses.) With the
exception of 486 based systems, recent AST designs now fully write protect
the shadowed BIOS areas.
The internal cache of the 486 chip presents a challenge to write protection
schemes which AST as well as all other vendors are faced with. Essentially
there are no hooks in the 486 which allow hardware designers to implement
write protection of shadowed areas which are covered by the 486's cache.
While full write protection could be achieved by preventing the 486 cache
from covering the video BIOS area, this results in a significant performance
degradation in video benchmarks.
The AST solution to the write protection dilemma of 486 systems is to write
protect the shadow RAM. While this does not prevent the cached copy of the
video BIOS from being overwritten, the cache will always be able to fetch a
correct copy from the protected shadow RAM whenever a cache load cycle is
done. This pseudo write protection of the video BIOS presents a much smaller
window of vulnerability to program bugs.
Permanent Shadowing:
All new AST systems and recent BIOS updates provide a feature called
permanent shadowing. This feature no longer provides the user with the
option to disable shadowing. With in-place shadowing and write protection of
the shadowed BIOS, there is little reason to disable shadowing. Disabling
shadowing only provides the user with a slower system. As mentioned earlier
the reserved memory is typically not returned back to the user when shadowing
is disabled.
Summary:
This paper has attempted to answer many of the persistent questions
surrounding shadowing. It has also reiterated the long term AST strategy
which, when implemented, results in the perfect shadowing scheme.

PREMIUM EXEC NI-CAD BATTERY INFORMATION
PROBLEM: All Nickel-Cadmium (Ni-Cad) rechargeable batteries have the
inherent "memory" property that can cause early low voltage
indications and premature system shutdown.
CAUSE: When a Ni-Cad battery is put through repeated partial-
discharge / recharge cycles, and is drained to approximately
the same level each time - down to half capacity, for example
- it develops a "memory" of this point in the discharge
process. Once established, Ni-Cad memory distorts the
battery's voltage output profile. The battery will produce a
normal voltage until drained to the memorized location, but
thereafter its voltage output abruptly sags to a sub-normal
value, and stays below normal until actual battery depletion.
The voltage depression can be deep enough to cause the
Notebook to prematurely issue the low battery warning (audible
beep and lighted amber LED) or battery fail warning (audible
beep and blinking amber LED.)
SOLUTION: The Ni-Cad battery "memory" effect can be corrected by
"conditioning" the battery, a process which simply consists of
fully discharging the battery before recharging.
The battery pack should never be disturbed while the system is
in use or while the battery is being charged. To remove or
install a battery, the system should be powered down and the
AC adapter removed.
AST recommends conditioning the battery pack monthly to
promote optimum performance. Conditioning of new, out-of-the-
box Ni-Cad battery pack is also strongly recommended. Listed
below are the steps required to correctly condition the
Premium Exec Ni-Cad battery:
1. Charge the Ni-Cad battery up to full capacity.
2. Disconnect the AC adapter.
3. Configure the Notebook's Setup Menu as shown below.
IMPORTANT: Note that Suspend must be ENABLED!
Default Speed: HIGH
Backlight Timeout: 0
Hard Disk Timeout: 0
Suspend: ENABLE
Software Timeout: 0
(Exec SX-25 and
SX-25 color only)
Turbo Mode: ON AT BOOT
Speaker: ENABLE
Other Parameters: Don't care
This configuration results in a near-maximum load on the battery during the
first part of the conditioning process. Suspend mode then prevents an
excessive drain rate as the battery nears depletion.
4. Store the setup menu setting and exit. The system will
reboot and the screen will display the DOS prompt.
5. Keep the Notebook powered up with its LCD display open for
12 TO 24 HOURS.
Most will find that overnight conditioning of the battery is the most
convenient method.
It is safe to use the Notebook in the normal fashion during the conditioning
process. However, the following precautions must be observed:
a. Save your work and exit all applications back to the DOS
prompt immediately after the first low battery warning.
Allow the Notebook to remain powered up with the LCD
display open, however.
b. A full 12 hours of on-time will insure complete battery
discharge even with premature suspend activation caused
by the "memory" effect.
6. After 12 hours, turn the Notebook off. Recharge the
battery by attaching the AC adapter. Connect the AC
adapter to the Notebook before plugging the adapter into
the AC socket. Connecting the AC adapter in this sequence
insures that the Notebook battery management system senses
all signals on the DIN connector appropriately.
NOTE: After completing a "fast discharge", wait at least 5 minutes before
connecting the AC Adapter/Charger to recharge the battery. If this is not
done, the AC Adapter/Charger could switch to Trickle Charge mode instead of
Fast Charge mode.

AST PREMIUM 486/33 WITH SQL SERVER
PROBLEM: SQL Server version 4.2 hangs during installation or log-on
while using the system administrators facility (SAF) with a
486DX processor card. This error occurs either in an ISA or
EISA system.
CAUSE: The problem has been isolated to the current version of BIOS.
If CMOS byte 41, bit 4 is high (co-processor disabled), SQL
Administrator will hang.
AFFECTED
SYSTEMS: 486DX/25 or 33 ISA or EISA.
SOLUTION: The following are two solutions available until a new version
of BIOS is released:
1) Using Debug type in the following instructions to determine
the status of the byte 41:
o 70 41 ;point to byte 41
i 71 ;get the byte
Then adjust the value so that bit 4 is low (example: F8h
becomes E8h). Write the new value back to CMOS using the
following instructions:
o 70 41 ;point to the byte
o 71 xx ;xx=new value in hex
2) Temporarily install a 386DX or SX processor board. Boot and
go into setup. Tab down to the field for Enable/Disable
Co-processor. Set to enable. Save and exit. Then,
reinstall the 486 processor board.

ASTIVGA.EXE ON THE PREMIUM II AND BRAVO SYSTEMS
PROBLEM: The Premium II User's Manual (AST part number 001129-001
revision X), refers to using a video utility called
ASTIVGA.EXE. When trying to access ASTIVGA.EXE, an error
occurs indicating that this file is not found. The problem is
a result of an upgrade to the System Utilities disk for DOS
5.0 support.
EFFECTED
SYSTEMS: Premium II and BRAVO
RESOLUTION: AST combined the ASTIVGA.EXE module with the ASTMENU.EXE
module. Unfortunately, the documentation does not reflect
the changes to the section regarding the proper use of the new
ASTIVGA.EXE. These additional commands were not added.
However, the following mode instructions will enable specific
mode commands to be entered from either the command line or from
within a batch file. These commands are not upper or lower case
sensitive.
SYNTAX: ASTMENU ASTIVGA <mode> [<option>]
PARAMETERS: <mode>
COLOR, MONO, EGA, CGA, MDA, HERC0, HERC1, 13225C, 13225M,
13243C, 13243M, 800C, 800M, LOCK, REBOOT
[<option>]
LOCK, REBOOT
The LOCK and REBOOT options may also be implemented as a <mode>
statement. LOCK maintains the selected mode through a
warm-boot, but is reset by a cold-boot, system reset, or if the
ASTIVGA.EXE program is repeated. The REBOOT option is used to
reboot the system into a particular mode. This option is
typically used to warm boot the system into a non-VGA environment.
If the selected mode is 800x or 132xxx, the REBOOT option will
revert back to the monitor's native mode.
EXAMPLES: ASTMENU ASTIVGA CGA REBOOT
ASTMENU ASTIVGA MONO LOCK
ASTMENU REBOOT

not attached!"
CAUSE: This problem is caused by an incompatibility between the
Carrier Corp. software protection key and the parallel port
implementation of the Premium Exec.
AFFECTED
SYSTEMS: Premium Exec 386SX-20 (All models)
Premium Exec 386SX-25 (All models)
Premium Exec 386SX-25C (All models)
SOLUTION: AST Sustaining Engineering has determined that this problem
will not be fixed on the Premium Exec. Carrier Corp. has
advised AST that a software patch may be available which eases
the timing requirements for accessing the security key.

AST 5251/11 ENHANCED AND PC GUARDIAN "VIRUS PREVENTION PLUS"
PROBLEM: When using the application "Virus Prevention Plus" from PC
Guardian Security Products, with AST 5251/11 Enhanced
emulation software, any attempt to unload emulation from
memory will result in a system lock-up.
CAUSE: With "Virus Prevention Plus" resident in memory, AST 5251/11
Enhanced emulation will not unload correctly because its
software interrupt vectors have been changed by the PC
Guardian software.
AFFECTED
SYSTEMS: AST 5251/11 Enhanced
SOLUTION: AST EPD Marketing has determined that this problem will not be
fixed. The AST 5251/11 Enhanced emulation product is working
as designed. To force emulation to unload after its software
interrupt vectors have been changed may corrupt the interrupt
vector chain and cause failures with other DOS applications.
As a work around, AST recommends either not loading "Virus
Prevention Plus" when using 5251/11 Enhanced emulation or
rebooting the system to unload emulation.

AST MONOCHROME VGA MONITORS
PROBLEM: When using the AST Monochrome VGA monitor near fluorescent
lighting, the display may flicker slightly, especially when
turning on fluorescent lights.
CAUSE: The flicker is caused by the frequency difference between the
fluorescent light (60Hz) and the scanning frequency of the
monitor (50Hz).
AFFECTED
SYSTEMS: AST Monochrome VGA monitors.
SOLUTION: It is recommended that any fluorescent lighting, such as that
found in modular workstations, be located at least 20" or more

AST POWER PREMIUM SYSTEMS AND HARDWARE CURSOR IMPLEMENTATION
PROBLEM: When using the AST Power Premium with Windows 3.X running in
32K color video modes, such as 640x480x32K, the mouse cursor
will blink when placed over areas of the Windows desktop that
are being redrawn.
CAUSE: The Western Digital 90C31 VGA controller is not specifically
designed to utilize the hardware cursor in 32K (16 bit) color
modes. This limitation is not a problem with the Western
Digital controller, but is caused by the lack of a color
palette in 32K color mode. In addition, mouse cursor width
and color availability would be adversely affected.
AFFECTED
SYSTEMS: AST Power Premium systems.
SOLUTION: Due to the limitations outlined above, a hardware cursor is
not implemented in 32K color mode.

AST SYSTEMS AND NORTON DESKTOP
PROBLEM: When running Norton Desktop under Windows 3.1 in 800x600 video
mode, the screen does not refresh correctly and all colors are
not displayed.
AFFECTED
SYSTEMS: Various AST 486 and 386 systems.
CAUSE: The problem occurs when the software tries to identify the
video controller and define a new color palette. It falsely
identifies our video as an EGA and hence we see the problem.
SOLUTION: The software has an undocumented switch that fixes this
problem.
The following line should be entered into the NDW.INI file,
which is located in the Windows directory.
[SYSTEM INFORMATION]
skipvideo=1
The editing should be done using a text editor such as the
Windows Notepad.

AFFECTED
SYSTEMS: All AST Power Premium systems
CAUSE: The problem is caused by a bug in the software due to which an
I/O write of F0h is executed to I/O port 816h, this is an
address at which EISA CMOS resides.
SOLUTION: A file named MIL.INI contained in the \penpoint\boot directory
should be modified as indicated below:
1. At line 145 change LPT1=true to LPT1=false
2. At line 147 change LPT2=true to LPT2=false

ADVANTAGE/BRAVO SYSTEMS AND AST/WINDOWS 3.1 LOGO SCREEN
Some AST Advantage and Bravo systems are shipped from the factory with
Microsoft Windows 3.1 pre-installed on the hard drive. The initial logo
screen which is displayed when Windows is started is a special logo, which is
a combination Microsoft and AST banner. When the Windows SETUP program is
used to change the default display driver from "VGA" to another type of
display driver, the "dual" logo is overwritten by the standard Microsoft-only
logo.
To restore the original "dual" logo, perform the following steps, first
making sure that Windows is not loaded:
1. From the DOS prompt, change directories to "n:\WINDOWS\SYSTEM", where
"n" is the drive where Windows is installed.
2. Using the DOS COPY command, copy the file ASTWLGO4.RLE to
VGALOGO.RLE.
3. Change directories to n:\WINDOWS.
4. Run SETUP and select DISPLAY from the "System Information" list.
5. Use the arrow keys to select VGA.
6. Accept this configuration.
7. Choose "use current driver" when prompted by SETUP, and exit SETUP.
The next time Windows is started, the logo screen should be as it was shipped
from the factory.

lock-ups during operation. Any attempt to open an application in a DOS
window will cause the operating system to generate a "SYS 3176" error, and
then lock up, forcing a power-off or reset to recover.
Customers experiencing this problem should contact IBM at 1-800-3-IBMOS2 and
request the Corrective Service Diskettes (CSD) update that will bring the
OS/2 operating system to CSD level "XR 06055".

AST 486 SYSTEMS WITH IBM'S 5250 EMULATION CARD
If an IBM 5250 adapter is installed in an AST 80486-based system, errors may
occur while accessing a high-density floppy drive. The DOS error generated
is "FAILURE READING DRIVE X: ABORT, RETRY, IGNORE, FAIL", where "X" is the
drive to which access is being attempted.
The problem occurs because the IBM 5250 emulation card, which defaults to
using IRQ 5, interferes with the operation of the floppy controller (at IRQ
6), causing DMA overruns.
To resolve this problem the following change needs to be made to the
configuration of the PC Support program.
In the STARTPCS batch file, at the line "E5250AH.COM" add the switch
"/L7". The command line should read "E5250AH /L7". A capital "L" must
be used.
This effectively changes the IRQ used by the IBM5250 adapter board
to 7. Note that no other device in the system should be using this
interrupt.

PREMIUM 486/25 SYSTEMS AND NOVELL NON-DEDICATED NETWARE 2.2
PROBLEM: After installing an Intel Overdrive processor (ODPR486DX-25)
into an AST Premium 486/25 system configured with Novell Non-
Dedicated Netware 2.2, the system will briefly display the
message "ABEND: Double Exception Interrupt" and then reboot
when attempting to start the server.
CAUSE: Novell Netware 2.2 uses timing dependent loops when toggling
the status of the GATEA20 line. With the Intel Overdrive chip
installed, this loop executes so quickly that the GATEA20 line
is not set to the proper state before Netware begins accessing
extended memory.
AFFECTED
SYSTEMS: AST CUPID Desktop Systems (motherboard part number 202356-00X
& 202337-00X).
SOLUTION: The file NET$OS.EXE may be patched to increase the length of
the timing dependent loops. The following procedure uses the
DOS DEBUG command to implement this fix:
c:\>copy net$os.exe net$os.bin<cr>
debug net$os.bin

BRAVO 4/33 LC AND IRWIN TAPE BACKUP UNIT
PROBLEM: Bravo 4/33 LC fails to recognize an Irwin A250EP Parallel Port
Tape Backup Unit. The EZ-Tape software that is provided with
the unit is unable to detect the tape drive connected to the
parallel port. This generates the error message "No tape
drive found."
CAUSE: The EZ-Tape software has several delay loops that are executed
too quickly on the Bravo 4/33 LC.
AFFECTED
SYSTEMS: All Bravo 4/33 LC systems.
SOLUTION: By patching the software and increasing the delay loops, the
EZ-Tape software can run properly on the Bravo 4/33 systems.
These delays can be added by manipulating an environment
string as follows:
SET PPCFDC=O:12,I:18
This string represents the environment for the Parallel Port
Controller Floppy Disk Controller (PPCFDC) to have an Output
delay factor of 12 (O:12) and an Input delay factor of 18
(I:18). These values were found to provide the best results
for the software to function properly. This environment
string can be typed at a DOS prompt before executing the EZ-
Tape software or by adding this line to the AUTOEXEC.BAT file.
This string will not decrease the functionality of the
software or system. The delay factors are only providing the
normal delay that would be done on systems that the software
was originally designed for.

BRAVO AND ADVANTAGE MEMORY ACCESS
The Bravo and Advantage computers utilize a memory addressing architecture
known as "interleaved", or "bank switched". Instead of placing sequential
memory addresses one after the other within the same bank of memory,
sequential memory addresses are interleaved between banks of memory. In the
case of 80386 systems, for example, the first 32-bit address is in Bank 0,
the second is in bank 1, and so forth for the number of banks installed.
Interleaving speeds memory access by enabling subsequent memory banks to be
prepared (precharged) for access while the data is being retrieved from the
current bank (address). Under normal operation, in a system with one bank
populated with memory, memory access is slower than when compared to a system
with two or more memory banks populated.

POWER EXEC MODEM SOFTWARE AND EMM386.EXE
PROBLEM: Communication software used for modems may experience problems
on the Power Exec if EMM386.EXE is used along with the Card
Configuration Utility (CCU.EXE) program, part number
910717-031 release 1.0. This currently occurs with all
versions of EMM386.
CAUSE: Both the EMM386 program and the CCU program load into memory
at the same D000h memory location. CCU.EXE takes two 16KB
memory windows; one at DC00h for PCMCIA common memory and one
at D800h for attribute memory. Also CCU will establish a
memory window at D000-D400h for network adapters which is
documented in the Power Exec User's Guide, part number
001492-001.
SYSTEMS
AFFECTED: All Power Exec systems.
SOLUTION: Exclude the D000h-DFFFh memory range in EMM386. This will
prevent EMM386.EXE from using this memory range and allow the
CCU program to use the memory range.
For example;
DEVICE=C:\EMM386.EXE X=D000-DFFF
For more information on EMM386 and the exclude switch, please
consult your MS-DOS manual. Make sure the appropriate files
are backed up before modifying this statement.

POWER EXEC WITH SUSPEND AND PARALLEL PRINTERS
The Power Exec may be unable to recognize the mouse when resuming from
Suspend if a printer attached to the parallel port is powered on. When
placing a Premium Exec or Power Exec system into suspend, make sure that the
printer that is hooked up to the parallel port is not powered up before
suspending your system.
The printer has its own power supply which is still connected to your
portable computer. This power supply leaks current into the peripheral
control area of the suspended system. This does not pose any serious
problems to the electronics inside the computer, but when the computer
resumes from suspend, the peripheral controller will not be able to
distinguish a PS/2 mouse or a SmartPoint trackball until any current
applications are reset.

POWER EXEC AND "MOUSE CONNECTED TO..." FIELD
The Power Exec's System Setup field "Mouse Connected To" is how the system
keeps track of a mouse connected to a serial port. The serial port may be on
the Power Exec, the EasyPort or PowerStation.
If you change the type of mouse to SmartPoint or PS/2, and forget to change
the "Mouse Connected To" field in System Setup, there will be no effects to
the correct operation of your system.
If you remove the mouse hardware completely, be sure to set "Mouse Connected
To" to "None" so that the system will know that your keyboard mouse may bring

Many software communications programs are dependent upon a fixed speed of the
CPU. One of the Power Exec's many power management attributes is its ability
to slow the CPU below the speed of a traditional desktop system. Any
communications software program which exhibits correctable errors or retries
is likely to be slaved to the CPU speed.

CUPID 486/33 SYSTEMS AND INTEL OVERDRIVE PROCESSOR UPGRADES
PROBLEM: After installing an Intel OverDrive processor (ODPR486DX-33)
into an AST Cupid 486/33 system, POST errors indicating memory
parity or memory verify errors may occur.
CAUSE: The problem has been traced to the high input capacitance of
the Signetics 74F543 transceiver part. The Signetics chip
input capacitance causes exaggerated signal reflections on the
data lines between the P-Bus and the microprocessor, resulting
in distorted waveforms and data errors when the ODPR486DX-33
