WSS(4)                     Kernel Interfaces Manual                     WSS(4)

     wss -- Windows Sound System hardware audio driver

SYNOPSIS

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.
