AKBD(4)                  BSD Kernel Interfaces Manual                  AKBD(4)

     akbd -- Apple Keyboard Device

     akbd* at adb?
     wskbd* at akbd? mux 1
     option AKBD_LAYOUT=XXX

     This driver supports ADB keyboards within the wscons(4) console frame-
     work.  It doesn't provide direct device driver entry points but makes its
     functions available via the internal wskbd(4) interface.

     The following is a partial list of supported AKBD devices:

           Apple Standard Keyboard
           Apple Extended Keyboard
           Apple Keyboard II
           Apple PowerBook Keyboard
           Apple Adjustable Keyboard
           Apple PowerBook extended Keyboard
           Apple PowerBook G3 Keyboard
           Apple PowerBook G4 Keyboard
           Apple iBook Keyboard

     The akbd driver supports a number of different key mappings which can be
     chosen from with the kernel option ``AKBD_LAYOUT'' at compile time or
     with the utility wsconsctl(8) (variable: ``keyboard.encoding'') at run-
     time.  Other mappings can be used if the whole keymap is replaced by
     means of wsconsctl(8).  The built-in mappings are at this time:

           KB_DE   (de) German with ``dead accents''.
           KB_ES   (es) Spanish.
           KB_FR   (fr) French.
           KB_JP   (jp) Japanese.
           KB_PT   (pt) Portuguese.
           KB_SF   (sf) Swiss French with ``dead accents''.
           KB_SG   (sg) Swiss German with ``dead accents''.
           KB_SV   (sv) Swedish with ``dead accents''.
           KB_UK   (uk) British.
           KB_US   (us) English/US keyboard mapping (default).

     The KB_DE, KB_FR, KB_SG and KB_SV mappings can be used in the KB_NODEAD
     (.nodead) variant.  This switches off the ``dead accents''.

     To set a German keyboard layout without ``dead accents'', use wsconsctl
     keyboard.encoding=de.nodead.  To set it at kernel build time, add the
     following to the kernel configuration file:

           option AKBD_LAYOUT="KB_DE|KB_NODEAD"

     adb(4), intro(4), ukbd(4), wskbd(4), wsconsctl(8)

     The akbd interface first appeared in NetBSD 0.9.  It has been under
     development ever since.

     Bradley A. Grantham wrote the original akbd driver, including the MRG
     support.  The hardware direct interface was written by John P.

     The list of built-in mappings doesn't follow any logic.  It grew as peo-
     ple submitted what they needed.
