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

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.
