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 drivers
60 device defined in the kernel configuration file.
61 This device also requires the
63 keyboard controller to be present.
66 number must always be 1; there is no provision of changing the number.
68 The AT keyboard has a number of function keys.
69 They are numbered as follows and can be associated with strings
74 .Bl -tag -width "Function Key Number" -compact
75 .It "Function Key number"
80 Shift+F1, Shift+F2,...\& Shift+F12
82 Ctl+F1, Ctl+F2,...\& Ctl+F12
84 Shift+Ctl+F1, Shift+Ctl+F2,...\& Shift+Ctl+F12
86 Home and Numpad 7 (without NumLock)

90 Page Up and Numpad 9 (without NumLock)
94 Left Arrow and Numpad 4 (without NumLock)
96 Numpad 5 (without NumLock)
98 Right Arrow and Numpad 6 (without NumLock)

104 Down Arrow and Numpad 2 (without NumLock)
106 Page Down and Numpad 3 (without NumLock)
108 Ins and Numpad 0 (without NumLock)
119 See the man page for the
121 command for how to assign a string to the function key.
122 .Sh DRIVER CONFIGURATION
123 .Ss Kernel Configuration Options
124 The following kernel configuration options control the
127 .Bl -tag -width ATKBD_DFLT
128 .It Em ATKBD_DFLT_KEYMAP
129 This option sets the default, built-in keymap of the
131 driver to the named keymap.
135 .It Em KBD_DISABLE_KEYMAP_LOAD
136 The keymap can be modified by the
139 This option will disable this feature and prevent the user from
140 changing key assignment.
146 driver accepts the following driver flags.
147 They can be set either in
148 .Pa /boot/device.hints ,
149 or else from within the boot loader
153 .It bit 0 (FAIL_IF_NO_KBD)
156 driver will install even if a keyboard is not actually connected to the
158 This option prevents the driver from being installed in this situation.
160 When this option is given, the
162 driver will not reset the keyboard when initializing it.
163 It may be useful for laptop computers whose function keys
164 have special functions and these functions are forgotten when the
166 .It bit 2 (ALT_SCANCODESET)
167 Certain keyboards, such as those on some ThinkPad models, behave
168 like the old XT keyboard and require this option.
169 .It bit 3 (NO_PROBE_TEST)
170 When this option is given, the
172 driver will not test the keyboard port during the probe routine.
173 Some machines hang during boot when this test is performed.
179 driver requires the keyboard controller
181 Thus, the kernel configuration file should contain the following lines.
186 The following example shows how to set the default, built-in keymap
191 .Dl "options ATKBD_DFLT_KEYMAP"
192 .Dl "makeoptions ATKBD_DFLT_KEYMAP=jp.106"
195 In both cases, you also need to have following lines in
196 .Pa /boot/device.hints .
198 .Dl hint.atkbdc.0.at="isa"
199 .Dl hint.atkbdc.0.port="0x060"
