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