Disable the IRQ on your video card. It is unnecessary. Most PC
BIOS's have an "Assign IRQ2 to VGA" enable disable in CMOS setup.
Set it to disable.

Perhaps it gets disabled on the video card by the video driver in
Win95. Or perhaps Win95 allows them to share, but the video card
doesn't use the IRQ so there are no problems.

You'll probably have to disable the VGA IRQ, or change the IRQ on
your SCSI card.

Probably.

Win95 is probably fooling you. I doubt it shares an IRQ with
anything.

Good point!

Just try disabling VGA IRQ. If not in your CMOS, then look at
your video card for a jumper to disable it. It is unused by any
software on the PC anyways...
