SND_ICH(4)		     Kernel Interfaces Manual		      SND_ICH(4)

NAME
     snd_ich -- Intel ICH AC'97 and compatible bridge device driver

SYNOPSIS
     To compile this driver into the kernel, place the following lines in your
     kernel configuration file:

	   device sound
	   device snd_ich

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

	   snd_ich_load="YES"

DESCRIPTION
     The  snd_ich  bridge driver allows the generic audio driver sound(4) to at-
     tach to Intel ICH AC'97 and compatible audio devices.

     Some later chips, like ICH6/ICH7, depending on wiring can instead implement
     newer Intel HD Audio specification, which is supported by	snd_hda(4)  dri-
     ver.
