 28.Dt SND_ICH 4
 29.Os
 30.Sh NAME
 31.Nm snd_ich
 32.Nd "Intel ICH AC'97 and compatible bridge device driver"
 33.Sh SYNOPSIS
 34To compile this driver into the kernel, place the following lines in your
 35kernel configuration file:
 36.Bd -ragged -offset indent
 37.Cd "device sound"
 38.Cd "device snd_ich"
 39.Ed
 40.Pp
 41Alternatively, to load the driver as a module at boot time, place the
 42following line in
 43.Xr loader.conf 5 :
 44.Bd -literal -offset indent
 45snd_ich_load="YES"
 46.Ed
 47.Sh DESCRIPTION
 48The
 49.Nm
 50bridge driver allows the generic audio driver
 51.Xr sound 4
 52to attach to Intel ICH AC'97 and compatible audio devices.
 53.Pp
 54Some later chips, like ICH6/ICH7, depending on wiring can instead implement
 55newer Intel HD Audio specification, which is supported by
 56.Xr snd_hda 4
 57driver.
