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:
· Gravis UltraSound PnP
· 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.
