- .Sh NAME
- .Nm snd_ich
- .Nd "Intel ICH AC'97 and compatible bridge device driver"
- .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_ich"
- .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

- .Ed
- .Sh DESCRIPTION
- The
- .Nm
- bridge driver allows the generic audio driver
- .Xr sound 4
- to attach to Intel ICH AC'97 and compatible audio devices.
