AKBD(4) BSD Kernel Interfaces Manual AKBD(4)
akbd -- Apple Keyboard Device
akbd* at adb?
wskbd* at akbd? mux 1
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:
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.
