Don:
Are you sure you have the Phar Lap DOS Extender upgraded to v2.6? Also,
remove EMM386 from your CONFIG.SYS file and the ,UMB from your DOS=HIGH
statement. Suddenly you'll see that baby load the whole drawing into
memory (no more swap writes and reclaims) and the loading time will
seriously decrease. Try setting the cache for 1Mb at most – extended
memory. Frankly, you may not need it at all (definitely not if the machine
is primarily used for AutoCAD).

I had problems with acad when using the ,UMB switch. Never did get around
to finding out why, but I didn't need it. The better solution is to use
QEMM, but DOS's Himem.sys will do in a pinch.
