DESCRIPTION
The wss driver supports Microsoft's Windows Sound System, 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 configuration file must have bit 1 set in flags 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 are, e.g., OPTi 82C928, 82C929,
82C831, and OAK OTI-601D. Bit 2 in flags disables the joystick port on
MAD16 hardware.
