comp.unix.sco Technical FAQ 2/7

Questions and Answers Specific to OpenServer Release 5

FAQ Starting Page http://aplawrence.com/SCOFAQ/index.html

These FAQS were developed and maintained for years by
[email protected] (Stephen M. Dunn). Steve no longer has the time to
maintain them, and has asked me to take them over. Please remember the
debt all of us owe to Steve for his efforts- I myself spent many hours
learning from these very documents, and I'm sure many of us can say
similar things.

Because Steve has not been able to maintain these for a while now,
some of the information herein is outdated. I am working to correct
that, but it's a lot to catch up on, so if you spot something, please
let me know. For the moment, I'm just marking some of it as probably
being useless; as I have time, I'll check further to be certain before
I remove anything.

Suggestion: Use my Search to find what you are looking for.

NOTE: There are also many questions which apply not only to OSR5 but
also to other Unix (and possibly Xenix) versions. If you don't see the
answer to your question here, please check the other sections of this
FAQ, as your question may be answered there.

Graphical characters don't work

OSR5 uses the IBM characters set by default. Try mapchan -n. If that
cures the problem, comment out the appropriate line in
/etc/rc.d/6/kinit - and make sure you make a note of this change so
that you can remake it, if necessary, after a future upgrade.

Bela Lubkin offered a slightly longer explanation:

(as explained by Bela)
SCO added a new alias for the console terminal emulation. The old one,
"ansi", is still recognized. However, the new one, "scoansi", is used
by default. There is no difference in the two terminal descriptions as
long as your application uses the standard sources of terminal
information: termcap (/etc/termcap) and terminfo
(/usr/lib/terminfo/?/terminalname).
However, many older applications are shipped with their own private
terminal files. For instance, SCO FoxPlus comes with
/usr/lib/foxplus/termcap. These private terminal descriptions are
usually a superset of the normal information, plus other stuff that
the application may use for its own purposes.
Your problem is probably happening because your application provides
its own termcap file with added information about line drawing. When
the console terminal was called "ansi", the app looked up "ansi" in
its private termcap and found out how to draw nice lines. Now that the
console is called "scoansi", it looks that up and doesn't find it, so
it falls back to the OS's public terminal description. That
description actually *does* say how to draw nice boxes, but perhaps
not in the same language that the application is expecting.
Solution: the easiest one is to just call your console terminals
"ansi". You can do that by editing the console entries in
/etc/ttytype. Next easiest: find the app's private terminal database
and teach it that "scoansi" is the same as "ansi".

sar doesn't work

First off - did you run sar_enable? This is a new command in OSR5
which sets everything up so that sar runs as it did previously. If sar
isn't enabled, it simply won't run. Run /usr/lib/sa/sar_enable -y for
starters. You will also need to edit root's and sys' crontab files if
you wish data to be collected 24 hours a day, seven days a week. Also,
if you wish to keep sar data for more than seven days, remove the
'find' command in the last line of /usr/lib/sar/sa2.

The file /etc/ps/booted.kernel gives the name of the booted kernel,
and sar needs this to work properly. This file gets created each time
the system is rebooted. In case it's messed up, try running kernel -uv
and see if that cures it.

There is another problem, though, which may not be cured by the above.
There is a bug in the code in /boot. If the inode number of the kernel
is greater than 32767, /boot improperly sign-extends it as a signed
short integer rather than an unsigned one, and the end result is a
completely wacky inode number. This should only happen on systems
without a separate boot filesystem, which generally means those which
were upgraded from an earlier release in place. The following is a
patch to /boot which should cure the problem in 5.0.0; the TA from
which it was derived (482688) states that this problem is for 5.0.0,
but it also exists in 5.0.2. Be VERY careful, as always, applying
patches; this one in particular may disable your system entirely if
not done correctly.

# cp -p /boot /boot.orig
# what /boot
/boot:
SCO boot 23 Apr 95
# sum -r /boot
00357 134 /boot

If either the results of what, or the results of sum -r, don't match
exactly what you see above, stop! Do not apply this patch unless these
are identical to the results you see.

# echo 3f:feb?h 90 | _fst -w /boot -
* 3f:feb?h 90
0x3f:0xfeb: 0x99 = 0x90
# sum -r /boot
09082 134 boot

Again, if the results of sum -r don't match exactly what you see,
something did not work correctly. You should copy /boot.orig back to
/boot.

My emergency floppies don't have enough inodes

The simplest change to this is to edit /usr/lib/mkdev/fd and increase
the number of inodes created from the default. This may cause
problems, though, as HTFS inodes consume 128 bytes each and a
significant increase in the number of inodes would result in a
significant drop in the number of data blocks available on the floppy.

A better change would be to eliminate unnecessary device nodes from
your emergency floppy. Look for a line in /usr/lib/mkdev/fd which sets
a variable called NOTREQ (which, roughly, is a list of device drivers
not required on an emergency diskette). Add to that list
merge mpm spm svdsp svkbd vdsp vkbd mouse
If you don't need pseudottys on your emergency diskettes, you might
also want to add spt mpt. There is also a bug in this file; change the
item ptspwr to pts pwr (by adding a space), and you will cut out a few
more unnecessary devices.

When editing /usr/lib/mkdev/fd, you should actually make a new copy
(e.g. /usr/lib/mkdev/fd.new) and edit, and later use, that rather than
/usr/lib/mkdev/fd. Otherwise, you may find your changes vanish at some
time in the future.

I'm having trouble with licensing and registration

First off, you may have up to three difference license
number/activation key combinations to use. Please read the
documentation and the COLA (Certificate Of License and Authenticity)
card(s) carefully. If you are upgrading from an old release of an SCO
product, you will be asked not only to type in your new SNAK (Serial
Number and Activation Key), but also the old SNAK from your old
release. Additionally, if you are upgrading to the Enterprise system,
you must first install and license the Host system, and then perform
an upgrade to Enterprise.

Licensing and registration is a two-step process. The first step
involves licensing, and this takes place when you enter the SNAK from
your COLA. You then fill in a form, included with your software, and
send it to SCO in any of a number of ways. SCO sends you a
registration key, which you enter to complete the registration
process. The registration key is dependent both on your serial number
and on a number generated by the system when you install it; this
latter half means that should you have to reinstall, you will need to
re-register your system.

One big problem many people have had is that in the case of an
Enterprise upgrade, you must register the Host system before you can
register the Enterprise system. If you do not, then you may end up
with a system which will appear to accept your registration but which
will subsequently complain that it has not been registered, and there
is no elegant way out of this situation; SCO recommends reinstalling
to cure this. SCO is working on a cure for this but it is not ready
yet and it will probably not be able to rescue systems which have
already experienced this problem.

If you need to do an upgrade or install and cannot wait for the
registration information to be sent back to you, there is a procedure
you can follow to avoid this problem. Install the Host system, and
then install the Enterprise system. Send SCO the registration
information for _both_ systems. When you receive your registration
keys, perform the following steps:

1. Take the system to single-user (maintenance) mode
2. Remove the Enterprise license. This does not mean removing the
software - just the license.
3. Register the Host system license.
4. Register the Enterprise system license.
5. Shut the system down (haltsys) - do not bring it back up to
multi-user mode without shutting down first

If you find yourself unregistering/unlicensing parts of your system
and you have a PANIC, it's possible that you may have upset the kernel
streams linker module. Try booting with the boot string defbootstr
ksl.disable; if that gets the system running, finish up your licensing
and registration work and then reboot with your usual boot string.

sysadmsh is missing

OSR5 includes sysadmsh, but it's not installed by default. If you wish
to use it, you will need to use custom (or SCOAdmin Software) to
install it.

_________________________________________________________________

Will Release 5 run my older binaries?

In general, yes; binaries from previous versions of SCO Unix or SCO
Xenix will run on OSR5. The exceptions tend to be those which probe
system internals, where such internals may have changed, or those
coded with certain assumptions (e.g. "an inode number is always a
16-bit quantity") which are not necessarily true on OSR5. Examples
include programs which read directories from disk rather than using OS
directory access routines, or those which look for kernel structures
and variables.

I loaded a patch but it didn't take effect

Loading/unloading and applying patches only applies through 5.0.2-
thanks to Dirk Hart for spotting this.

You probably forgot to apply it. Loading a patch places the contents
of the patch on the hard drive, but does not activate the patch.
Applying the patch does the necessary replacement of system files and
whatever other adjustments are required to make the patch take effect.
For more detailed information on the actual procedures, consult your
manuals.

You may wish to load a patch, but not apply it, for several reasons.
Another machine on the network can apply a patch directly from your
machine's hard drive if you've loaded the patch. Also, you may find
that you will have to roll back several patches to replace or remove
an earlier one, and then reapply the ones you rolled back; having
loaded the patches first saves you from having to use the diskettes
again.

[Table of Contents]
_________________________________________________________________

What patches should I use?

There is information in the file
ftp://ftp.sco.com/README.OSR5.Supplements, including a list of
currently applicable patches, and some quick summary information on
which patches should not be used in conjunction with each other. For
more detailed information, read the documentation files accompanying
each specific patch.

There's also a Web page,
http://www.sco.com/support/toolbox/patch.html, with a minimum patch
list.

[Table of Contents]
_________________________________________________________________

What patches are on my system?

To see which patches have been loaded, start SCOAdmin Software or
custom and pick Software -> Patch Management -> View Loaded Patches

Checking the list of patches which have been applied may be more of a
problem; there is no simple way of doing this with SCOAdmin. You can
pick Software -> Examine -> Applied Patches, and then pick each
component in turn to see what patches have been applied to it. Yes,
SCO is aware that this is a pain, so hopefully there will be a better
way in a future release.

If you are running OSR5.0.0 with the rs500d release supplement
applied, or OSR5.0.2 or later, there is a command-line method,
customquery listpatches, which will list what patches have been
applied. This option to customquery did not exist prior to rs500d; if
you do not have rs500d applied to your system, you should.

What's this free copy of SCO Unix I keep hearing about?

On 19 August 1996, SCO announced that the single-user (desktop)
configuration of OpenServer Release 5 would be available free of
charge for noncommercial use. The package includes OSR5 Desktop, the
development system (C/C++ compilers), SCO Doctor Lite, and SCO
ARCserve/Open Lite.

Since then, SCO has also released a free version of SCO UnixWare.

For full details, including the license terms and on-line ordering
information, see http://www.sco.com/offers/.

I'm having trouble using my ATAPI CD-ROM

The two most common problems are that your "IDE" CD-ROM drive may not
follow the ATAPI spec, or that you are unsure of what parameters to
enter when asked for the configuration of your drive. Check the
drive's documentation, or consult the manufacturer, for the first
problem.

The support for ATAPI CD-ROMs in OSR5 is done by using a driver which
makes the drive appear to be a SCSI drive, and so you need to enter
the same information as for a SCSI drive. The correct answers are as
follows:

* Host Adapter Number (HA): 0 if your drive is connected to your
primary IDE host adapter, and 1 if it's connected to a secondary.
* SCSI ID: 0 if your drive is a master, and 1 if it's a slave
* Logical Unit Number (LUN): Always 0
* Bus number: Always 0

If all of these have been done correctly and the drive still does not
work, try changing its configuration. If it's the master on the
secondary host adapter, try making it a slave on the primary, or vice
versa.

Also, on some systems there is a conflict with the driver for the
Western Digital/Future Domain 7000. If you don't have such a card, and
your machine hangs at a line including wdhainit, boot with defbootstr
disable=wdha to disable the wdha driver. There have also been reports
of conflicts with the dptr and ncr drivers. For more information on
disabling drivers, see the section entitled "My kernel locks up at
boot time" in section 3.

My >2GB ATA hard drive doesn't work with OSR5

See the documentation for oss451b to see if it applies to you. The two
most commonly reported problems which are fixed by this patch are the
system being unable to find the root filesystem, or aborting during
installtion with a message similar to "NOTICE: ram: No space on device
31/50", but there are other problems also fixed by it.

My floppy drive doesn't work reliably

First things first - it may be a bad diskette, a bad floppy drive, or
the cable connecting your floppy drive to its controller may be loose.

However, if the problem gets worse if the system is under load
(particularly, when anything is doing DMA - and that usually means a
SCSI host adapter) and is particularly bad when trying to format a
floppy, you may be running into a problem with the FIFO on the floppy
controller.

Briefly, older floppy controllers have a one-byte buffer, and the
system must grab that byte before the next byte is read from the drive
or else you have a problem. If the DMA controller (floppies use DMA)
is blocked long enough, usually by a SCSI host adapter, the buffer
gets overwritten. Newer controllers generally have a 16-byte buffer,
but it may or may not be turned on by your BIOS. SCO Unix doesn't
program the buffer by default, but the floppy driver in OSR5 can be
set to use the buffer if you wish.

Make a backup of /etc/conf/pack.d/fd/space.c (just in case). Now edit
the file. At the bottom you will see

int fd_enable_FIFO = 0;
int fd_FIFOthresh = 0;

Change them to

int fd_enable_FIFO = 1;
int fd_FIFOthresh = 15;

The first one simply enables or disables programming of the FIFO; the
second one sets the FIFO's size if you've enabled it. There's probably
no reason to set it to anything other than 15.

Relink and reboot to activate the change.

Making this change can actually be counterproductive if your system is
working properly. Some floppy drive controllers will not work properly
if you try enabling the FIFO, and you will end up with a system with
floppy drives which do not work. Trust me on this one.

People log out but still show up in who

This information is logged in /etc/utmp and /etc/utmpx. In 5.0.4, this
information is cleared when the system reboots. For earlier releases,
edit /etc/bcheckrc as follows. You will see the first of the following
three lines already there; add the other two below it.

/bin/su bin -c "/etc/devnm / 2>/dev/null" | /etc/setmnt
[ -w /etc/utmp ] && > /etc/utmp
[ -w /etc/utmpx ] && > /etc/utmpx

Also, "cwtmp" ftp://ftp.armory.com/pub/scobins/cwtmp is a freely
available utility that clears stale logins.

Can I perform an in-place upgrade?

If you already have your package, consult the documentation (in
particular, installation guide and release notes).

5.0.4

* Can IPU from: 5.0.0 and 5.0.2
* Cannot IPU from: Internet Faststart or ODT 3/Unix 3.2v4.2 or
earlier
* Caveats: If you IPU, you cannot install Internet Manager; you must
do a fresh install if you ever want it.

5.0.2

* Can IPU from: ODT3/Unix 3.2v4.2
* Cannot IPU from: 5.0.0, Internet Faststart, older Unix versions

5.0.0

* Can IPU from: ODT3/Unix 3.2v4.2
* Cannot IPU from: Older Unix versions

Note that if you are doing an in-place upgrade from ODT3/Unix 3.2v4.2
to OSR5, you will not get a separate boot filesystem, and you cannot
upgrade your root filesystem to HTFS.

For an article that explains why you wouldn't do an IPU, see
http://aplawrence.com/Unixart/upgrades.html.

Bela Lubkin supplied the following chart; it's out of date and
probably of little interest with regard to the older parts, but I've
included it anyway:

-IPU-> In-place upgrade possible (start full OS install of target
release, by booting N1 or N00 floppy; it will prompt you whether
you want to upgrade)

-SUP-> In-place upgrade by installing supplement (named at end of line)

~N/A~> Upgrade not possible in a single step (may be possible via
intermediate steps; but as in-place upgrades are always a little
shaky, you probably don't want to compound then -- better to do
fresh-install and migrate applications & data)

"Open Desktop family" = Open Desktop, Open Desktop Lite, Open Desktop
with Server Supplement, Open Server Network System, and/or Open
Server Enterprise System (different titles available at
different release levels).

"OpenServer" = OpenServer Host, Desktop, Enterprise Systems. A license
is required to do an upgrade, and must be purchased for the
specific upgrade path (e.g. SCO Unix 3.2v4.2 -> OpenServer Host
System 5.0.2 would require a different license than SCO Unix
3.2v4.2 -> OpenServer Enterprise System 5.0.2)

>Bela<

Jean-Pierre Radley reported that the 5.06 from 5.0.5 IPU was "almost
to my liking".

You don't have access to the search tools this way, but you can
simulate that with the following cgi-bin script.

Can I use the scohelp server as a Web server?

Yes, although you'd probably be wiser to consider something like
Apache (http://www.apache.org/; it's also available as part of
Skunkware). If you wish to use the scohelp server, follow the
instructions in TA 482609 or at
http://www.sco.com/Technology/internet/servers/scohttp80.html.

Is there a packet sniffer (tcpdump) available?

A collection of network tools, including the tcpdump packet sniffer,
can be found at http://www.sco.com/skunkware/osr5/net/nettools/. Pay
particular attention to the requirements mentioned in the README file.
For example, you will need a dedicated NIC to make this work.

What can I do about function keys not working?

A new "recon" command in Open Server 5.0.6 can help solve the problem
of escape sequences (function keys, line drawing characters, etc.)
getting messed up because of timing issues- what happens is that the
application gets confused if the sequences don't arrive together. The
"recon" command watches for escape sequence and buffers them until
they are complete, then sends them along. See
http://osr5doc.sco.com:457/cgi-bin/man/man?recon+C

Can I have both IDE and SCSI Drives?

Mixing SCSI and IDE drives can be a problem if you want the root disk
to be scsi. The short answer is that you can if your BIOS lets you
select which drive to boot (if not, you would have to boot from a
floppy). Assuming everything else is in place, "defbootstr hd=Sdsk"
should work. See SCSI for a full discussion of this.

Is there a DHCP client for OSR5?

SCO doesn't currently have a DHCP client for OSR5 (modern releases do
have a DHCP server) built in, but it's available as TLS711
ftp://ftp.sco.com/TLS/tls711.tar.Z

[Table of Contents]
_________________________________________________________________

Can OSR5 do NAT or ip filtering (function as a firewall)?

Yes, with "ipfilter"- it's built into 5.0.6 and is available as a
supplement for 5.0.4 and 5.0.5- TLS709 ftp://ftp.sco.com/TLS/. But
note this Sept 14 2000 post from Kamal Mostafa:

The 'ip' driver included in TLS709 needs the routine bcmp(), which
didn't appear in the kernel until 5.0.4. After I discovered this
problem, I fixed the 'ip' driver so that it no longer needs bcmp(). So
the latest version of the 'ip' driver (e.g. from a 5.0.6 system) will
work on 5.0.x systems. Eventually, I will update TLS709 with the newer
version. In the meantime, replace the /etc/conf/pack.d/ip/Driver.o
that TLS709 put there with a newer version. If anyone else is getting
this problem, you can either lift the 'ip' driver from a 5.0.6 system,
or contact me directly and I'll email you a replacement binary as
well. Kamal A. Mostafa SCO Engineering

Kamal has given me permission to put this driver on my ftp site; you
can download it from ftp://ftp.aplawrence.com/pub/ip-Driver.o. Copy it
to /etc/conf/pack.d/ip/Driver.o and relink your kernel (make a safe
copy of your ip/Driver.o first).

You'll also need netstat: ftp://ftp.aplawrence.com/pub/netstat. Copy
that to /usr/bin and

chown bin:mem /usr/bin/netstat
chmod 2711 /usr/bin/netstat

Again, be sure to save a copy of your original netstat!

Can OSR5 and Unixware run Linux binaries?

Yes. The "lxrun" may already be installed; if not, get it from
Skunkware.

[Table of Contents]
_________________________________________________________________

Can Linux run OSR5 binaries?

Generally, yes. It requires the ibcs2 module. Aside from library
problems, you are apt to find directory structure problems (usually
easy enough to fix with symbolic links) and, if the application calls
OS commands, you may need to make appropriate links for some of those,
too.

How can I recreate my install floppy?

The floppy image is available on the CDROM in the "images" directory.
A "readme" file is also there that explains how to create the floppy.

I've added more ram, do I need to increase swap?

Not necessarily. There is a detailed discussion of this at
http://aplawrence.com/Boot/swap.html, but the main points are:
* If you have enough RAM, you don't need ANY swap.
* However, if you are concerned with saving panic dump information,
you WILL need sufficient dump space.
* You can add swap space without resizing divisions by using the
"swap" command to swap to a file; see "man swap" and :

How much swap space do I need?

Can I add more swap space?

Why do I get "dynamic linker" errors or load failures?

If you get an error like the following.
dynamic linker: svrmgrl: error opening libprogram.so
Killed

install_driver(program) failed: Can't load

PERL_MODULE::program: dynamic linker: perl: relocation error: symbol not
found: getrusage at....

These messages all mean that you do not or have not setup
LD_LIBRARY_PATH variable or Your Program isn't setting up
LD_LIBRARY_PATH correctly, or your install of the program was faulty.

This can be solved by adding the shell variable LD_LIBRARY_PATH or
LIBPATH with the proper search path. For example if you are using
bourne or korn shell

LD_LIBRARY_PATH=/usr/lib:/lib:/usr/local/lib:/usr/ccs/lib:/usr/local/mysql/lib:
/usr/local/BerkeleyDB.3.1/lib
LIBPATH=/usr/lib:/lib:/usr/local/lib:/usr/ccs/lib:
export LD_LIBRARY_PATH LIBPATH

From the man page on ld:
LD_LIBRARY_PATH is also used to specify library search directories to the
dynamic linker at run time. That is, if LD_LIBRARY_PATH exists in the
environment, the dynamic linker will search the directories it names
before its default directory for shared objects to be linked with the program
at execution.

Why do I get "cronsched: no response from server" messages ?

This is related to the Calendar server- see "man calendar" and "man
scocalendar". Usually this means that something is broken, so if you
aren't using calendar, and therefor don't care that it is broken, you
can just comment out the "cronsched" entries from root's crontab.

If you do care, see http://www.sco.com/cgi-bin/ssl_reference?102995.

What does "ifor_pmd, failed to initialize policy manager" mean?

The license manager is failing for some reason. There are a number of
reasons why that could be, including having an incorrect date in your
computer's BIOS or simply not having a /pmd directory. See
http://www.sco.com/cgi-bin/ssl_reference?104851 for more detailed
reasons and fixes.

What causes "No utmp entry, must login from lowest level shell"

Probably corruption in one of the log files /etc/utmp, /etc/wtmp,
/etc/utmpx, or /etc/wtmpx. You can zero them out by:

> /etc/utmp
> /etc/utmpx
> /etc/wtmp
> /etc/wtmpx

and then rebooting. i

Robert Bailin says that he's seen the corruption caused by
/etc/cleanup being run by cron; see I need information from "last",
but most of it is gone!

Does SCO OpenServer5 support the 'undelete' feature?

Yes, it does but unfortunately it's not active by default (see the
online manual pages for details). To activate it: pre> - scoadmin ->
Hardware/Kernel Manager - MAXVDEPTH = max number of versioned files -
MINVTIME = seconds after which files get versioned relink+reboot To
activate file versioning on a directory: - undelete -s

Why do I have to relink after just changing an ip address?

The kernel knows its own ip address, even in single user mode where
TCP/IP is obviously not running. A machine in init state 1 will still
respond to pings, for example.

So you'd think perhaps that's why you need to relink, but a little
experimentation shows that even without relinking, a single user
machine still responds to the address put in with netconfig.

Apparently, then, there is no reason to relink if you are just
changing IP addresses- it works fine without it.

Why does the installation bomb out with a "Signal 8" error ?

Contributed by Roberto Zini

Under SCO OpenServer 5.0.5 this is mainly a symptom of a memory
problem. In the "SCO OpenServer 5.0.5 Release Notes" booklet, SCO
states that your system must have at least 32MB of RAM to succesfully
install OpenServer. If you have less, the following message is likely
to appear on the screen:

Reading from install source 10 Kb/ramFs/extractProd/extractAll
terminated by signal 8

To solve this problem on a 16MB system, you can restart the
installation and type the "notebook" strings while at the boot prompt.
Alternatively, reinstall the system by typing the following at the
boot prompt:

defbootstr nbuf=100

How Can I stop OpenServer 5.0.6 creating /usr/local as a sym-link?

a) After the install remove /usr/local and re-create as required. BUT
- if you do this and then at some point in the future you run custom
verify and let it fix the discrepencies then your /usr/local will be
moved to /usr/local# and the sys-link will be re-created.

b) Edit the Custom+ database to stop custom complaining. WARNING -
Incorrect Editing the Custom+ database WILL give you problems - be
carefull.

You need to comment out one line in the file

/var/opt/K/SCO/Unix/5.0.6Ga/.softmgmt/RTS.fl

The line is:

EXPORT r ./usr/local /usr/local

You can use a script similar to:
----- Cut Here ---------
DIR=/var/opt/K/SCO/Unix/5.0.6Ga/.softmgmt
FILE=RTS.fl
sed -e 's/^EXPORT r .*local$/#&/' < ${DIR}/${FILE} >${DIR}/$$
mv ${DIR}/$$ ${DIR}/${FILE}
----- Cut Here ---------

to do it for you.

Is it possible to have more than one instance of custom running ?

John Boland posted the following a while ago (please change the
reference to SCO OS 5.0.2 (5.0.2Dp) with the one related to the 5.0.x
version you're using) :

=== cut here ===

The lock file is:

/var/opt/K/SCO/Unix/5.0.2Dp/custom/client.lock

Move this file aside and you can run as many Software Managers (custom)
as you like.

How can I access the documentation on the install CD if I don't yet have a SCO
system installed?

The install CD can be read from a Windows machine, and the
documentation is in html format. There are also Windows tools included
to make boot disks etc.

I need information from "last", but most of it is gone!

The default root crontab cleans out /usr/adm/sulog, /etc/wtmp and
/etc/wtmpx on Sunday mornings. The script that does this is
/etc/cleanup.

If your machine is used at the time this script is run, you will want
to change the time in crontab. If you want more than 1 week's
information in these files, you need to change its frequency or take
it out all together.

How can I assign a user process to a specific pseudo tty?

How can I get pci bus information?

First, you probably don't need to. This usually comes up because a
network card isn't working and you think that you must have the wrong
pci information. More likely, you just don't have the most current
driver- for example, Intel Pro100 cards are very apt to need a new
driver(check ftp://ftp.sco.com/pub/drivers ).

However, if you really do need this information "hw -r pci" will tell
you everything you need to know and more. The "hw" command was not
included with 5.00 and 5.0.2, but can be obtained from ftp.jpr.com. It
will also work on 3.2v4.2.

I upgraded Merge and now cannot access my floppy drive

David Peet explains:

New to Merge 4.1.1 for OpenServer, the floppy is now accessed in the
same way as it is on Merge for Unixware (via the UNIX floppy driver)
instead of "direct attached" as it had been done. This change is
because on faster machines the direct attach of the floppy often has
problems because of timing.

For a Win95 that was installed when direct attach floppy was being
used, the registry needs to be updated so that Windows can use the new
accesss method.

The problem is that Merge is supposed to update your existing Windows
registry when you upgrade to 4.1.1, and this update must have failed
insome way. (Any new installation of Windows after the upgrade will
not have the problem. It is only an issue of changing the hardware
setup for an existing Windows installation.)

What is supposed to happen is that the program
/usr/lib/merge/bin/upgrade_flop.sh

is supposed to be run the first time you use Merge after upgrading.
This is supposed to update the registry.

Either this did not get run automatically or it failed someway. You
can retry this by running it. Just running it (with no parameters)
will upgrade your regular Windows installation as specified by your
"win" personal configuration. If you have other personal windows95
configurations, you need to run this script for each one, using as a
parameter the name of the configuration.

If this does not work you have two choices:
1. Reinstall Windows so the new installation will work with the new
floppy access method.
2. Change Merge to use direct attach floppy access so old
installations of Windows will work as is.
+ Change the MERGE_DIRECT_FLOPPY_ENABLE switch in
/etc/default/merge from off to on.
+ Edit /etc/conf/pack.d/merge/space.c and change the value of
_M_direct_attach_floppy from 0 to 1 and rebuild a kernel
(/etc/conf/cf.d/link_unix -y) and then reboot.
