WSS(4)                    NetBSD Programmer's Manual                    WSS(4)


NAME

     wss - Windows Sound System hardware driver


SYNOPSIS

     device wss0 at isa? port 0x530 irq 10 drq 0 drq2 1
     device wss0 at isa? port 0x530 irq 10 drq 0 flags 1
     audio* at wss?


DESCRIPTION

     The wss driver supports Microsoft's Windows Sound System, MAD16 chip
     based hardware and their clones.  The Windows Sound System is a half-du-
     plex 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 7, 9, 10, or 11, and the DMA channel
     may be set to 0, 1, or 3.

     The configuration file must use a 1 flags specification 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.


BUGS

     The FM synthesizer is not supported.
