NAME

SYNOPSIS
     For PnP cards:
     device gusc

     For non-PnP cards:
     device gusc0 at isa? port 0x220 irq 5 drq 1 flags 0x13

DESCRIPTION
     The gusc bridge driver allows the generic audio drivers including pcm(4)
     to	attach to the following	ISA sound cards:

     +o	 Gravis	UltraSound PnP

     +o	 Gravis	UltraSound MAX

     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.
