You'll need to configure the MS-DOS shortcut to the proggie Memory tab to use Auto in the DPMI section (Dos Protected Mode Interface).
Or - you'll need to load DOS high, Himem.sys and Emm386.exe in the config.sys file on the bootdisk...like this;
DOS=HIGH,UMB;
DEVICE=C:\WINDOWS\HIMEM.SYS /TESTMEM:ON
DEVICE=C:\WINDOWS\EMM386.EXE
the /TESTMEM:ON can be omitted or made to /TESTMEM:OFF if desired...
review the Msdosdrv.txt file found in \Windows dir. for more info on settings...and make sure these files above (Himem.sys and emm386.exe) are in the dir as listed (WINDOWS)
