.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
