- Scott:
- I don't have the definitive answer, by any means, but I've heard
- that ACAD11 wants total control over memory and has a real tough time
- if there's any conflict. I have 2 486/33 systems from different mfgrs.
- On one, ACAD11 runs fine under QEMM386; on the other, it snails under
- either QEMM386 or DOS's HIMEM.SYS, but runs fine with neither.
- I'm guessing you have HIMEM.SYS installed and have the same problem
- I have. That's a real bummer, since without a high memory manager,
- all devices have to load low and eat up memory.
- If you find a solution, or get good EMAIL responses, please share
- them with me.
