Yes, you guessed correctly, and if you have registered you will be getting
the newest version of the DRDOS EMM386.SYS that runs Windows correctly!

DRDOS still can solve your problem by using a smart config.sys!
Look at the following example and try to see if you can arrange yours similarly.

.........................................................................
:START
SHELL=C:\COMMAND.COM c:\ /P /E:256
?"DO YOU WANT TO RUN WINDOWS IN ENHANCED MODE (Y/N)?" GOTO WINDOWS
?"DO YOU WANT TO LOAD EMM386.SYS WITH LIM MEMORY (Y/N)?" GOTO WITHLIM
?"DO YOU WANT TO LOAD EMM386.SYS WITHOUT LIM MEMORY (Y/N)?" GOTO NOLIM
?"DO YOU WANT TO START OVER (Y/N)?" GOTO START
GOTO COMMON
:WINDOWS
DEVICE=C:\WIN3\HIMEM.SYS
DEVICE=C:\DRDOS\HIDOS.SYS /B=FFFF
DEVICE=C:\WIN3\SMARTDRIVE
GOTO COMMON
:WITHLIM
HIDOS=ON
DEVICE=C:\DRDOS\EMM386.SYS /F=AUTO /K=xxxx /B=FFFF /R=AUTO
GOTO COMMON
:NOLIM
HIDOS=ON
DEVICE=C:\DRDOS\EMM386.SYS /F=NONE /K=AUTO /B=FFFF /R=AUTO
GOTO COMMON
:COMMON
BREAK=ON
BUFFERS=20
FILES=20
FCBS=4,4
FASTOPEN=512
etc...etc...etc...
...............................................................

This config.sys will prompt for the proper configuration you need, i.e.,
if you want to run a DOS program that uses expanded memory you make the LIM
choice, for windows choose windows at start up.
This is a basic example, no network drivers loaded into hi memory, but,
you should be able to add these items in the COMMON area!

Good Luck! And have fun with DRDOS.
