     atkbd -- the AT keyboard interface


     options ATKBD_DFLT_KEYMAP
     makeoptions ATKBD_DFLT_KEYMAP=_keymap_name_
     device atkbd

     In /boot/device.hints:


     The atkbd 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 drivers syscons(4) and pcvt(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 fol-
     lows 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
     49 		  Home and Numpad 7 (without NumLock)
     50 		  Up Arrow and Numpad 8 (without NumLock)
     51 		  Page Up and Numpad 9 (without NumLock)
     52 		  Numpad -
     53 		  Left Arrow and Numpad 4 (without NumLock)
     54 		  Numpad 5 (without NumLock)
     55 		  Right Arrow and Numpad 6 (without NumLock)
     56 		  Numpad +
     57 		  End and Numpad 1 (without NumLock)
     58 		  Down Arrow and Numpad 2 (without NumLock)
     59 		  Page Down and Numpad 3 (without NumLock)
     60 		  Ins and Numpad 0 (without NumLock)
     61 		  Del
     62 		  Left GUI Key
     63 		  Right GUI Key
     64 		  Menu

     See the man page for the kbdcontrol(1) command for how to assign a string
     to the function key.


   Kernel Configuration Options
     The following kernel configuration options control the atkbd driver.

		 from changing key assignment.

   Driver Flags
     The atkbd driver accepts the following driver flags.  They can be set
     either in /boot/device.hints, or else from within the boot loader (see

     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 key-
	   board 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 key-
	   board port during the probe routine.  Some machines hang during
	   boot when this test is performed.


     The atkbd driver requires the keyboard controller atkbdc.	Thus, the ker-
     nel configuration file should contain the following lines.

	   device atkbdc
	   device atkbd

     The following example shows how to set the default, built-in keymap to

	   device atkbdc
	   makeoptions ATKBD_DFLT_KEYMAP=jp.106
	   device atkbd

     In both cases, you also need to have following lines in



     kbdcontrol(1), atkbdc(4), pcvt(4), psm(4), syscons(4), loader(8)


     The atkbd driver first appeared in FreeBSD 3.1.


     The atkbd driver was written by Soren Schmidt <sos@FreeBSD.org> and
