48 driver, together with the
50 driver, provides access to the AT 84 keyboard or the AT enhanced keyboard
51 which is connected to the AT keyboard controller.
53 This driver is required for the console driver
58 device defined in the kernel configuration file.
59 This device also requires the
61 keyboard controller to be present.
64 number must always be 1; there is no provision of changing the number.
66 The AT keyboard has a number of function keys.
67 They are numbered as follows and can be associated with strings
72 .Bl -tag -width "Function Key Number" -compact
73 .It "Function Key number"
78 Shift+F1, Shift+F2,...\& Shift+F12
80 Ctl+F1, Ctl+F2,...\& Ctl+F12
82 Shift+Ctl+F1, Shift+Ctl+F2,...\& Shift+Ctl+F12
84 Home and Numpad 7 (without NumLock)
86 Up Arrow and Numpad 8 (without NumLock)
88 Page Up and Numpad 9 (without NumLock)
92 Left Arrow and Numpad 4 (without NumLock)
94 Numpad 5 (without NumLock)
96 Right Arrow and Numpad 6 (without NumLock)
100 End and Numpad 1 (without NumLock)
102 Down Arrow and Numpad 2 (without NumLock)
104 Page Down and Numpad 3 (without NumLock)
106 Ins and Numpad 0 (without NumLock)
117 See the man page for the
119 command for how to assign a string to the function key.
120 .Sh DRIVER CONFIGURATION
121 .Ss Kernel Configuration Options
122 The following kernel configuration options control the
125 .Bl -tag -width ATKBD_DFLT
126 .It Em ATKBD_DFLT_KEYMAP
127 This option sets the default, built-in keymap of the
129 driver to the named keymap.
133 .It Em KBD_DISABLE_KEYMAP_LOAD
134 The keymap can be modified by the
137 This option will disable this feature and prevent the user from
138 changing key assignment.
144 driver accepts the following driver flags.
145 They can be set either in
146 .Pa /boot/device.hints ,
147 or else from within the boot loader
151 .It bit 0 (FAIL_IF_NO_KBD)
154 driver will install even if a keyboard is not actually connected to the
156 This option prevents the driver from being installed in this situation.
158 When this option is given, the
160 driver will not reset the keyboard when initializing it.
161 It may be useful for laptop computers whose function keys
162 have special functions and these functions are forgotten when the
164 .It bit 2 (ALT_SCANCODESET)
165 Certain keyboards, such as those on some ThinkPad models, behave
166 like the old XT keyboard and require this option.
167 .It bit 3 (NO_PROBE_TEST)
168 When this option is given, the
170 driver will not test the keyboard port during the probe routine.
171 Some machines hang during boot when this test is performed.
177 driver requires the keyboard controller
179 Thus, the kernel configuration file should contain the following lines.
184 The following example shows how to set the default, built-in keymap
189 .Dl "options ATKBD_DFLT_KEYMAP"
190 .Dl "makeoptions ATKBD_DFLT_KEYMAP=jp.106"
193 In both cases, you also need to have following lines in
194 .Pa /boot/device.hints .
196 .Dl hint.atkbdc.0.at="isa"
197 .Dl hint.atkbdc.0.port="0x060"
