|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver supports Microsoft's Windows Sound System, the MAD16 chip based
|
|
hardware, and their clones.
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
The device
|
|
.Cm 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
|
|
.Cm flags
|
|
disables the joystick port on MAD16 hardware.
