#SLOWWWWW ACAD
Joe,
In my experience, it's possible to get the SLOWWWWW ACAD problem with DOS5
even with NEWDX and/or QEMM. On my system, I have already run NEWDX. If I
set up EMM386 or QEMM386 to provide EMS memory all is OK. If I disable EMS
and use the memory manager only for high memory loading of drivers, etc.,
one of two things happens:
1. ACAD refuses to load and complains that another program has put the
microprocessor in real mode.
2. ACAD loads and all seems OK but drawings load VERY slowly, REGENs take
forever, etc. STATUS reports only a fraction of the RAM (I have 16 MB) as
being available for ACAD.
Thus I must have EMS enabled to use either memory manager. With QEMM386
this isn't too bad since EMS memory is only taken from XMS when needed.
EMM386 takes the memory at boot time. In both cases, however, I lose 64K
of upper memory for a page frame.
Since ACAD isn't using EMS this situation doesn't seem to make sense.
What's going on?
