NAME
atkbd - the AT keyboard interfaceSYNOPSIS
options ATKBD_DFLT_KEYMAP makeoptions ATKBD_DFLT_KEYMAP=_keymap_name_ options KBD_DISABLE_KEYMAP_LOAD device atkbdIn /boot/device.hints hint.atkbd.0.at=atkbdc hint.atkbd.0.irq=1
DESCRIPTION
The ifconfig 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 ifconfig 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.

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 the ifconfig driver.- ATKBD_DFLT_KEYMAP
- This option sets the default, built-in keymap of the ifconfig 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 ifconfig 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 ifconfig 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 ifconfig 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 ifconfig driver will not test the keyboard port during the probe routine. Some machines hang during boot when this test is performed.
EXAMPLES
The ifconfig 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"
