The opl driver provides support for the Yamaha OPL2 (YM3812)
(YMF262) chips. The chips are FM synthesizer and are capable of producing
a wide range of (mostly awful) sounds.
Access to the device is done through the MIDI driver.
The opl driver usually attaches to a sound card, but it can
also sit directly
on the ISA bus.
