DESCRIPTION
The
driver, together with the
atkbdc
driver, provides access to the AT 84 keyboard or the AT enhanced keyboard
which is connected to the AT keyboard controller.
This driver is required for the console driver
syscons(4).
There can be only one
device defined in the kernel configuration file.
This device also requires the
atkbdc
keyboard controller to be present.
The
irq
number must always be 1; there is no provision of changing the number.
Function Keys
The AT keyboard has a number of function keys.
They are numbered as follows and can be associated with strings
by the
kbdcontrol(1)
command.
"Function Key number"
Function Key
"1, 2,...12"
F1, F2,... F12
"13, 14,...24"
Shift+F1, Shift+F2,... Shift+F12
"25, 26,...36"
Ctl+F1, Ctl+F2,... Ctl+F12
"37, 38,...48"
Shift+Ctl+F1, Shift+Ctl+F2,... Shift+Ctl+F12

See the man page for the

DRIVER CONFIGURATION
Kernel Configuration Options
The following kernel configuration options control the
driver.
ATKBD_DFLT_KEYMAP
This option sets the default, built-in keymap of the
driver to the named keymap.
See
Sx EXAMPLES
below.
KBD_DISABLE_KEYMAP_LOAD
The keymap can be modified by the
kbdcontrol(1)
command.
This option will disable this feature and prevent the user from
changing key assignment.
Driver Flags
The
driver accepts the following driver flags.
They can be set either in
/boot/device.hints
or else from within the boot loader
(see
loader(8)).
bit 0 (FAIL_IF_NO_KBD)
By default the
driver will install even if a keyboard is not actually connected to the
system.
This option prevents the driver from being installed in this situation.
bit 1 (NO_RESET)
When this option is given, the
driver will not reset the keyboard when initializing it.
It may be useful for laptop computers whose function keys
have special functions and these functions are forgotten when the
keyboard is reset.
bit 2 (ALT_SCANCODESET)
Certain keyboards, such as those on some ThinkPad models, behave
like the old XT keyboard and require this option.
bit 3 (NO_PROBE_TEST)
When this option is given, the
driver will not test the keyboard port during the probe routine.
Some machines hang during boot when this test is performed.
EXAMPLES
The
driver requires the keyboard controller
atkbdc
Thus, the kernel configuration file should contain the following lines.
"device atkbdc"
"device atkbd"
The following example shows how to set the default, built-in keymap
to
jp.106.kbd
"device atkbdc"
"options ATKBD_DFLT_KEYMAP"
"makeoptions ATKBD_DFLT_KEYMAP=jp.106"
"device atkbd"
In both cases, you also need to have following lines in
/boot/device.hints
