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.
NetBSD includes machine-independent Open Firmware ISA
drivers, sorted by device type and driver name:
- wdc
- Standard Western Digital type hard drive controllers: MFM, RLL, ESDI, and
IDE/ATAPI.
- com
- NS8250-, NS16450-, and NS16550-based serial ports.
- lpt
- Standard ISA parallel port interface.
- cs
- Cirrus Logic Crystal CS8900 Ethernet interfaces.
- ess
- ESS Technology AudioDrive 1788-, 1888-, 1887-, and 888-based sound
cards.
- joy
- Game (joystick) adapters.
The Open Firmware ISA subsystem appeared in NetBSD 1.4.
