Hi, I've been trying to run my Orchid Prodesigner VGA card in VGA mode with the QEMM386 extended memory manager installed. Unfortunately, there appears to be some sort of memory/addressing (?) conflict. Trying to use VGA (or EGA) mode causes an error message "Exception.." to appear after which the machine reboots. Is there any way to prevent QEMM from using high memory between 640 and 1000k? I think something similar has been discussed here before, but I missed it. Any help/pointers would be very appreciated. (Disabling Video BIOS shadowing doesn't seem to make any difference.) Thanks, Paolo Coppi (coppi@tapir.caltech.edu)

Make sure to exclude A000-C7FF, those are addresses which belong to VGA (any VGA, not just the Prodesigner) -- Phil Ngai, phil@amd.com {uunet,decwrl,ucbvax}!amdcad!phil A PC without DESQview is like Unix without ^Z.
