DESCRIPTION
     The opl driver provides support for the Yamaha OPL2 (YM3812) and OPL3
     (YMF262) chips.  These are FM synthesizer chips and are capable of pro-
     ducing 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 di-
     rectly on the ISA bus.
