DESCRIPTION
Thewss
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.
