.Sh NAME
.Nm pci
.Nd introduction to machine-independent PCI bus support and drivers
.Sh SYNOPSIS
.Pp
.Cd "pci* at mainbus? bus ?"
.Cd "pci* at pchb? bus ?"
.Cd "pci* at ppb? bus ?"
.Pp
Other
.Nm
attachments are machine-dependent and depend on the bus topology and
.Tn PCI
bus interface of your system.
See
.Xr intro 4
for your system for details.
.Sh INTRODUCTION
.Nx
includes a machine-independent
.Tn PCI
bus subsystem and
several machine-independent
.Tn PCI
device drivers.
.Pp
Your system may support additional
.Tn PCI
devices.
Drivers for
.Tn PCI
devices not listed here are machine-dependent.
Consult your system's
.Xr intro 4
for additional information.
