This ASCII file explains how to obtain the use of UPPER MEMORY
BLOCKS on a Tandy 1000SX or TX using the MICRO MAINFRAME EXPANDED
MEMORY BOARD and EMS 4.0 DRIVER.

1.  THE 3.2 DRIVER WILL NOT WORK.
2.  YOU MUST HAVE A FULL 640K.  This means you must be using an
   EGA or a VGA board.  If you are using the Tandy built in
   RGB video you do not have access to a full 640k as a part of
   it is used for video.
3.  I am using QRAM V1.0.  I do not know if other versions will
   work.
4.  You must not use OPTIMIZE as this will place QRAM back at the
   beginning of the CONFIG.SYS file.
5.  You must place the line QRAM.SYS FL=1 FEMS after the EMS4.BIN
   driver.  This will create 48k of UMB's.  QRAM.SYS FL=0 FEMS
   will create 64k of UMB's but you will not have access to any
   of the remaining memory on your expanded memory board.  Using
   QRAM.SYS should, according to the documentation, do the same
   thing, but returns a message saying QRAM has nothing to do.
6.  Oddly enough, utilities DO NOT SEEM TO BE ABLE TO FIND my
   expanded memory.  MFT says I have none as does PC Tools and
   MEM.  MSD says I have 6423K of Extended (DON'T I WISH) and no
   EXPANDED, but I do have 23K of free XMS UMB's.
7.  Hyperdisk has no trouble finding the expanded memory on my
   machine and using it as cache.
8.  RAMDRIVE.SYS will not work.  You have to create a ram drive
   using the driver that came with the MICRO MAINFRAME.  I have
   found that the ramdrive created on my machine is a bit flaky
   so use with caution.  Could be a generic driver out there
   that will work better.
9.  GEOS has no problem finding and using the Expanded memory if
   I do not use a ramdrive.

As you can see from my config.sys I am using the PCT 286
accelerator.  This also works using the 8088-2 that came with the
SX or a V20.  I have tried both.  My current DOS version is 5.0.

After completion of CONFIG.SYS and AUTOEXEC.BAT, a LOADHI command
brings up the following:

 1     D458 - D473     0.4K   Used (SETVER)

I no longer use WARPVF so there are 23K available as of this
date.  I hope you find this information useful.
