45 driver supports Microsoft's Windows Sound System, the MAD16 chip based
46 hardware, and their clones.
48 The base I/O port is set by a jumper on the board; valid choices are
49 0x530, 0x604, 0xE80, or 0xF40.
50 Both IRQ and DMA channels are software programmable.
51 The IRQ may be set to 7, 9, 10, or 11, and
52 the DMA channel may be set to 0, 1, or 3.
56 must have bit 0 (value 1) set to enable the MAD16 support. This is to
57 avoid potential conflicts with other devices when probing the MAD16
58 because it requires use of extra I/O ports not in the base port range.
59 Chips needing this flag include the OPTi 82C928, 82C929, 82C831, and
60 the OAK OTI-601D. Setting bit 1 (value 2) in
62 disables the joystick port on MAD16 hardware.
