Both cards show BusMaster- when it should be BusMaster+. Also both
cards have 2 BARs instead of 3. Check your BIOS settings to see if
there's a switch to enable bus mastering. This is an AGP card right?
If it was a PCI card I'd say plug it into another slot since some
slots on some mobos can't do bus mastering, but if it's AGP the only
thing left is a BIOS switch. Just guessing at this point.
