.Sh NAME
.Nm pcibios
.Nd introduction to PCI BIOS support
.Sh SYNOPSIS
.Cd "options PCIBIOS"
.Cd "#options PCIBIOSVERBOSE"
.Cd "options PCIBIOS_INTR_FIXUP"
.Cd "#options PCIINTR_DEBUG"
.Cd "options PCIBIOS_BUS_FIXUP"
.Pp
.Sh INTRODUCTION
.Nx
provides support for setting up PCI controllers, bridges, and devices
using information extracted from the BIOS.
.Pp
Ideally, the boot firmware of a machine (a.k.a. BIOS) should set
up all PCI devices; assigning them I/O and memory addresses and
interrupts. Alas, this does not always happen, so there is some
PC specific code that can do the initialization when
.Nx
boots.
.Pp
Options:
.Bl -tag -width PCIBIOS_INTR_FIXUP -offset 3n -compact
.It Nm PCIBIOS
turn on the PCI BIOS support.
.It Nm PCIBIOSVERBOSE
make the setup procedure verbose.
.It Nm PCIBIOS_INTR_FIXUP
fixup PCI interrupt routing.
.It Nm PCIINTR_DEBUG
super-verbse PCI interrupt fixup.
.It Nm PCIBIOS_BUS_FIXUP
fixup PCI bus numbering; needed for many
.Xr cardbus 4
bridges.
.El
.Sh BUGS
The PCI BIOS support does not yet assign I/O and memory addresses.
.Sh SEE ALSO
.Xr cardbus 4 ,
.Xr pci 4
.Sh HISTORY
The
.Nm
code appeared in
.Nx 1.5 .
