DESCRIPTION

     The opl driver provides support for the Yamaha OPL2 (YM3812) and OPL3
     (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.
