If the BIOS calls are polled then > assigning an IRQ is quite optional The only way a motherboard BIOS would know if the PCI BIOS used polling methods instead of interrupt methods is if it was a built in device. For all non-built in devices, it can't assume it won't need an interrupt if the card uses interrupts at all. I find it extremely unlikely that there exists a motherboard BIOS that *doesn't* at least assign the I/O space area and the IRQ for all bootable devices on the system, regardless of PnPOS settings. Name one concrete example of a motherboard BIOS that doesn't and I'll recant. -- Doug Ledford http://people.redhat.com/dledford Please check my web site for aic7xxx updates/answers before e-mailing me about problems
