.Sh DEPRECATION NOTICE
|
|
This driver is scheduled for removal prior to the release of
|
|
.Fx 14.0 .
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel, place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device sound"
|
|
.Cd "device snd_gusc"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a module at boot time, place the
|
|
following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
snd_gusc_load="YES"
|
|
.Ed
|
|
.Pp
|
|
Non-PnP cards require the following lines in
|
|
.Xr device.hints 5 :
|
|
.Bd -literal -offset indent
|
|
hint.gusc.0.at="isa"
|
|
hint.gusc.0.port="0x220"
|

.Sh DESCRIPTION
|
|
The

|
|
bridge driver allows the generic audio driver
|
|
.Xr sound 4
|
|
to attach to Gravis UltraSound sound cards.
|
|
.Pp

|
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.
