This sounds like it could be a broken PCI bios - there are a number about. The normal thing that happens is that Linux asks the BIOS about the specs of the card (address, IO ports, irq) and uses that if you don't override it. It seems the bios is saying the card's on irq 0, which is silly. You can: - Play with the bios config and see if it has anything about PCI interrupts - Try using overrides on the lilo command line - Ask your vendor for a new BIOS and see how that goes. As far as interrupts go, you should map PCI interrupt A to a spare one (9 seems common), and set it to level triggered. You should use interrupt A because a number of PCI motherboards don't implement B, C or D properly or at all. J
