DESCRIPTION

     The opl driver provides support for the Yamaha OPL2 (YM3812) and OPL3
     (YMF262) chips.  The chips are FM synthesizers and are capable of produc-
     ing a wide range of (mostly awful) sounds.

     Access to the device is through the MIDI driver.

     The opl driver usually attaches to a sound card, but it can also sit di-
     rectly on the ISA bus.


BUGS

     The OPL3 chip is operated in OPL2 mode despite being more capable.
