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
