User's Manual

Forces to use PCI BIOS, and not to access the hardware device directly. For instance, this parameter

may be used if the machine has a non-standard PCI host bridge.

• pci=nobios

Disallows use of PCI BIOS; only direct hardware access methods are allowed. For instance, this

parameter may be used if you experience crashes upon boot-up, probably caused by the BIOS.

• pci=biosirq

Uses PCI BIOS calls to get the interrupt routing table. These calls are known to be buggy on several

machines and they hang the machine when used, but on other computers it is the only way to get the

interrupt routing table. Try this option, if the kernel is unable to allocate IRQs or discover secondary

PCI buses on your motherboard.
