[comp.sys.ibm.pc] Orchid Prodesigner VGA& QEMM386 trouble

coppi@karl.tapir.Caltech.EDU (Paul Coppi) (02/28/90)

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)

It's working for me. Right this very instant.

Did you RTFM? Make sure to exclude A000-C7FF, those are addresses which
belong to VGA (any VGA, not just the Prodesigner)
