DESCRIPTION
     The wss driver supports Microsoft's Windows Sound System, the MAD16 chip based hardware, and
     their clones.

     The base I/O port is set by a jumper on the board; valid choices are 0x530, 0x604, 0xE80, or
     0xF40.  Both IRQ and DMA channels are software programmable.  The IRQ may be set to 7, 9,
     10, or 11, and the DMA channel may be set to 0, 1, or 3.

     The device flags must have bit 0 (value 1) set to enable the MAD16 support.  This is to
     avoid potential conflicts with other devices when probing the MAD16 because it requires use
     of extra I/O ports not in the base port range.  Chips needing this flag include the OPTi
     82C928, 82C929, 82C831, and the OAK OTI-601D.  Setting bit 1 (value 2) in flags disables the
     joystick port on MAD16 hardware.
