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 sup-
port. This is to avoid potential conflicts with other devices when prob-
ing 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.
