But you do _not_ have two PCI busmastering devices.  A video card is
not a bus mastering device, the only bus master you have is the NCR
53C810.

If anything I would syspect the Diamond Stealth 64 video 2001, I have
heard nothing but nightmares from my freinds down the street who build
regular PC for DOS/Windows/WIN95 when they try to use these things on
just about anyones motherboard.

It sounds like maybe the bios on the VGA card or the motherboard bios
are not doing the right thing with respect to memory space assignment.

Yea, try someone elses S3-968 based card, Miro, Number Nine, anyone
but diamond and you'll probably be running just fine.
