YDS(4)                   BSD Kernel Interfaces Manual                   YDS(4)

NAME
     yds -- Yamaha DS-XG audio device

SYNOPSIS
     yds* at pci? flags 0x0000
     audio* at yds?

DESCRIPTION
     The yds driver supports Yamaha DS-XG based sound chips, as found in,
     e.g., many Sony Vaio notebooks.

     The flags can be used to pass additional information to the yds driver.

     A value of 0x1000 forces the driver to disable the Sound Blaster legacy
     mode.  This is needed to make the floppy work on some machines but is
     disabled by default because it is known to break apm(4) support.

FILES
     The driver needs a firmware file, which is loaded on demand when the
     device is attached:

           /etc/firmware/yds

SEE ALSO
     ac97(4), audio(4), intro(4), pci(4)

HISTORY
     The yds driver first appeared in OpenBSD 2.9.
