I've recently been buying some modern software for my ancient 386dx system;
Stacker v4, and QEMM v7.04. Stacker has worked fine, but I'm having a
problem getting QEMM to co-exist with djgpp. I've seen various messages on
the list about QEMM and DPMI before, but I didn't pay much attention to
them. The first problem was that QDPMI sets up (only) a 1 MB default vm swap
file, which limits djgpp somewhat :-) That one was easy to fix. Now, trying
to run a djgpp-compiled version of djpeg, I get the message:
C:\TMP djpeg -gif -nodither scene.jpg >scene.gif
DPMI: Not enough memory (0x00520000 bytes).
Insufficient memory (case 3)
Okay, let's see what go32 has available:
C:\TMP go32
go32 version 1.11.maint5 Copyright (C) 1993 DJ Delorie
Lowest version I can run is 1.08
go32.exe usage: go32 [-d {debugger}] [{program} [{options} . . . ]]
go32.exe build time was Sun May 01 17:42:22 1994
DPMI memory available: 5076 Kb
Swap space available: 20000 Kb
Yes, 5076 KB < 0x520000 bytes, but I thought the whole point of virtual
memory was to eliminate these kinds of hassles. I was able to work around
the problem in this case by cutting the size of my disk cache to free up
more memory, but the question is: what kinds of incantations to I have
to tell to QEMM / QDPMI to eliminate this problem? Or, is 'set go32=nodpmi'
the best answer? (I haven't tried nodpmi yet.)
I looked through various QEMM and djgpp docs, but was unable to come up
with a solution. Further information (perhaps useful to the knowlegeable
and/or fanatic) is provided below...
