Notez bien: the 4th PCI Slot shares an IRQ-LINE (yes a LINE) with the aic7890, thus meaning whenever the 7890 gets an IRQ the 4th PCI slot does too.... I got this info from the asus manual but I don't recall exactly where... I do know that a friend mobo didn't install Linux NOR NT because it had a card in slot 4... So try it without it... We've also noticed that even when you're running at 66mhz bus you'll need 100mhz memory with the Asus P2B-DS, this due to timing with the BX chipset.
