I hope this is not too far off topic,
I recently had to completed some low level development for a DOS environment
and chose to go back to the old ZDB debugger/idde. Can anyone remember a
problem with version 3.1 that crashes the debugger with either an fmap error
or "INSUFFICIENT MEMORY". I've loaded it onto a DOS 6.22 machine and tried
with and without EMM386 with the same result. The code doesn't seem to
matter as I've been using the std hello program. I've tried the standard,
virtual and 286 versions with the same result. I've also tried running it
from zwb under win3.11, win95, win98 with the same result, I don't remember
this problem originally but it is many years since I used it.
By the way Version 3.0 works fine and all the other 3.1 tools, compiler ,
zwb work as well.
Thanks in advance,
        Paul

DEVICE=C:\DOS\HIMEM.SYS /INT15=8048 might work
