Windows 386 versions 2.1 and 2.11 cannot run when EMM386.EXE from
MS-DOS 5.0 or later is loaded in the CONFIG.SYS file. Attempting to
use this configuration results in the following error message:
This problem occurs regardless of which switches are used with
EMM386.EXE. To run Windows/386 2.1x, you cannot use EMM386.EXE to
emulate expanded memory or load drivers high.
Other device drivers from the Microsoft MS-DOS 5.0 Upgrade to be aware
of are listed in the README.TXT file section 4.5.
The following is an excerpt from the README.TXT file:
4.5 "High Memory Area in Use" Message (Windows/386 2.1)
You cannot run Windows/386 2.1 when MS-DOS 5.0 is loaded into the high
memory area. Also, the MS-DOS 5.0 versions of SMARTDRV.SYS and
RAMDRIVE.SYS are not compatible with Windows/386 2.1. To run
Windows/386 2.1 with MS-DOS 5.0, use the versions of SMARTDRV.SYS and
RAMDRIVE.SYS that came with Windows and remove the DOS=HIGH command,
if any, from your CONFIG.SYS file.
