PCI(4)                    OpenBSD Programmer's Manual                   PCI(4)

NAME
     pci - introduction to PCI bus support

SYNOPSIS
     pci* at mainbus? bus ?
     pci* at pchb? bus ?
     pci* at ppb? bus ?

     Other pci attachments are machine-dependent and depend on the bus topolo-
     gy and PCI bus interface of your system.  See intro(4) for your system
     for details.

DESCRIPTION
     The system includes a machine-independent PCI bus subsystem and several
     machine-independent PCI device drivers.

     Your system may support additional PCI devices.  Drivers for PCI devices
     not listed here are machine-dependent.  Consult your system's intro(4)
     for additional information.

   Details specific to the i386
     Note that interrupt mappings on the i386 may require that you configure
     your BIOS to reserve sufficient interrupts as "PCI/ISAPnP" so that there
     are sufficient interrupts remaining to configure the discovered PCI de-
     vices.  For more information, see pcibios(4).
