     The emu device driver appeared in OpenBSD 3.1.


     The emu driver was written by Yannick Montulet
     <yannick.montulet@epitech.net> and ported to OpenBSD 3.1 by
     Michael Shalayeff <mickey@openbsd.org>.



     Hardware interface of this card contains registers not used for normal
     operation, but potentially dangerous and not possible to disable. Poten-
     tial damage ranges from frying the card to frying motherboard or external
     equipment connected to its outputs.


     Currently, this driver does not support MIDI, joystick input or the
     multi-voice capability.
