routing table. These calls are known to be buggy
on several machines and they hang the machine when used,
but on other computers it's 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.
rom [IA-32] Assign address space to expansion ROMs.
Use with caution as certain devices share address
decoders between ROMs and other resources.
irqmask=0xMMMM [IA-32] Set a bit mask of IRQs allowed to be assigned
automatically to PCI devices. You can make the kernel
exclude IRQs of your ISA cards this way.
pci=option[,option...] [PCI] various PCI subsystem options:
off [IA-32] don't probe for the PCI bus
bios [IA-32] force use of PCI BIOS, don't access
the hardware directly. Use this if your machine
has a non-standard PCI host bridge.
nobios [IA-32] disallow use of PCI BIOS, only direct
hardware access methods are allowed. Use this
if you experience crashes upon bootup and you
suspect they are caused by the BIOS.
conf1 [IA-32] Force use of PCI Configuration
Mechanism 1.
conf2 [IA-32] Force use of PCI Configuration
Mechanism 2.
nosort [IA-32] Don't sort PCI devices according to
order given by the PCI BIOS. This sorting is
done to get a device order compatible with
older kernels.
biosirq [IA-32] Use 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's the only
way to get the interrupt routing table. Try
this option if the kernel is unable to allocate

irqmask=0xMMMM [IA-32] Set a bit mask of IRQs allowed to be
assigned automatically to PCI devices. You can

this way.
pirqaddr=0xAAAAA [IA-32] Specify the physical address
of the PIRQ table (normally generated
by the BIOS) if it is outside the
F0000h-100000h range.
lastbus=N [IA-32] Scan all buses till bus #N. Can be useful
if the kernel is unable to find your secondary buses
and you want to tell it explicitly which ones they are.
assign-busses [IA-32] Always assign all PCI bus
numbers ourselves, overriding
whatever the firmware may have
done.
usepirqmask [IA-32] Honor the possible IRQ mask
stored in the BIOS $PIR table. This is
needed on some systems with broken
BIOSes, notably some HP Pavilion N5400
and Omnibook XE3 notebooks. This will
have no effect if ACPI IRQ routing is
enabled.
noacpi [IA-32] Do not use ACPI for IRQ routing
or for PCI scanning.
routeirq Do IRQ routing for all PCI devices.
This is normally done in pci_enable_device(),
so this option is a temporary workaround
for broken drivers that don't call it.
firmware [ARM] Do not re-enumerate the bus but
instead just use the configuration
from the bootloader. This is currently
used on IXP2000 systems where the
bus has to be configured a certain way
for adjunct CPUs.

references to other documentation (C files, READMEs, ..), added S390,
PPC, SPARC, MTD, ALSA and OSS category. Minor corrections and
reformatting.
