SND_GUSC(4)	       FreeBSD Kernel Interfaces Manual		   SND_GUSC(4)

NAME
     snd_gusc -- Gravis	UltraSound ISA bridge device driver

SYNOPSIS
     To	compile	this driver into the kernel, place the following lines in your
     kernel configuration file:

	   device sound
	   device snd_gusc

     Alternatively, to load the	driver as a module at boot time, place the
     following line in loader.conf(5):

	   snd_gusc_load="YES"

     Non-PnP cards require the following lines in device.hints(5):

	   hint.gusc.0.at="isa"
	   hint.gusc.0.port="0x220"
	   hint.gusc.0.irq="5"
	   hint.gusc.0.drq="1"
	   hint.gusc.0.flags="0x13"

DESCRIPTION
     The snd_gusc bridge driver	allows the generic audio driver	sound(4) to
     attach to Gravis UltraSound sound cards.

     The value of flags	specifies the secondary	DMA channel.  If the secondary
     DMA channel is C, set the flags to	(C | 0x10).  For a sound card without
     the secondary DMA channel,	the flags should be set	to zero.

HARDWARE
     The snd_gusc driver supports the following	sound cards:

     +o	 Gravis	UltraSound MAX
     +o	 Gravis	UltraSound PnP

DIAGNOSTICS
     xxx: gus pcm not attached,	out of memory  There are not enough memory to
     drive the device.
