     wss - Windows Sound System hardware driver

SYNOPSIS    [Toc]    [Back]

     wss0 at isa? port 0x530 irq 10 drq 0 flags 1
     wss* at isapnp?
     audio* at wss?

DESCRIPTION    [Toc]    [Back]

     The wss driver supports Microsoft's  Windows  Sound  System,
MAD16 chip
     based  hardware  and their clones.  The Windows Sound System
is a half-duplex
 device.

     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 5, 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.  Bit 2 in flags disables the joystick  port
on MAD16
     hardware.
