# 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.
