NAME

     pci - introduction to machine-independent PCI bus support and drivers


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.


INTRODUCTION

     NetBSD includes a machine-independent PCI bus subsystem and several ma-
     chine-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.


SUPPORTED DEVICES

     NetBSD includes machine-independent PCI drivers, sorted by device type
     and driver name:

   SCSI interfaces

                    faces.

   Network interfaces

                    the DE435, DE450, and DE500, and Znyx, SMC, Co-
                    gent/Adaptec, and Asante single- and multi-port Ethernet
                    interfaces.  Multi-port interfaces are typically config-
                    ured as a PCI-PCI bridge with multiple de instances on the
                    PCI bus on the other side of the bridge.
