MMPC 10/20  (250-1640/41)  Customizing Memory for EMS   Faxback Doc. # 3562
Sensation  (250-1651)

Using the following CONFIG.SYS and AUTOEXEC.BAT will give you 2 MB of
EMS (expanded) memory, while still keeping the highest amount of free
conventional memory.  Also listed is an addition to the SYSTEM.INI file.

CONFIG.SYS

WIN


Note:  By default, Windows will not load when using the monochrome memory
       region (B000-B7FF) as extended memory.  A system with SVGA can use
       the monochrome region with an addition to the SYSTEM.INI file.
       Use a text editor and add the following line under the [386Enh]
       section:

          DEVICE=C:\DOS\MONOUMB.386

       The file MONOUMB.386 should be in the DOS directory.  With this
       line added, B000-B7FF can be used as extended memory, and Windows
       will work fine.

Free Expanded (EMS)*                 2,097,152 (2048K)

* EMM386 is using XMS memory to simulate EMS memory as needed.
  Free EMS memory may change as free XMS memory changes.

Largest executable program size        630,688  (616K)
Largest free upper memory block         16,368   (16K)
MS-DOS is resident in the high memory area.
