NAME¶
atkbd
—
SYNOPSIS¶
options ATKBD_DFLT_KEYMAP
makeoptions ATKBD_DFLT_KEYMAP=_keymap_name_
options KBD_DISABLE_KEYMAP_LOAD
device atkbd
In /boot/device.hints:
hint.atkbd.0.at="atkbdc"
hint.atkbd.0.irq="1"
DESCRIPTION¶
Theatkbd
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) or vt(4).
There can be only one atkbd
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. You can use a keyboard map file (see kbdmap(5)) to map them to arbitrary keys, particularly the functions in the range from 65 to 96 which are not used by default.- Function Key number

See the man page for the kbdcontrol(1) command for how to assign a string to the function key.
DRIVER CONFIGURATION¶
Kernel Configuration Options¶
The following kernel configuration options control theatkbd
driver.
- ATKBD_DFLT_KEYMAP
- This option sets the default, built-in keymap of the
atkbd
driver to the named keymap. See 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¶
Theatkbd
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
atkbd
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
atkbd
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
atkbd
driver will not test the keyboard port during the probe routine. Some machines hang during boot when this test is performed.
EXAMPLES¶
Theatkbd
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.
hint.atkbdc.0.at="isa"
hint.atkbdc.0.port="0x060"
hint.atkbd.0.at="atkbdc"
hint.atkbd.0.irq="1"
