NAME
     ofisa - introduction to machine-independent Open Firmware ISA bus support
     and drivers

SYNOPSIS
     ofisa* at mainbus0
     XX*    at ofisa?

DESCRIPTION
     NetBSD includes a machine-independent ISA bus subsystem and several
     machine-independent ISA device drivers.  The ofisa bus uses Open Firmware
     to determine how to attach devices.

HARDWARE
     NetBSD includes machine-independent Open Firmware ISA drivers, sorted by
     device type and driver name:

   Disk and tape controllers
           wdc   Standard Western Digital type hard drive controllers: MFM,
                 RLL, ESDI, and IDE/ATAPI.

   Serial and parallel interfaces
           com   NS8250-, NS16450-, and NS16550-based serial ports.

           lpt   Standard ISA parallel port interface.

   Network interfaces
           cs    Cirrus Logic Crystal CS8900 Ethernet interfaces.

   Sound cards and MIDI interfaces
           ess   ESS Technology AudioDrive 1788-, 1888-, 1887-, and 888-based
                 sound cards.

   Miscellaneous devices
           joy   Game (joystick) adapters.
