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
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
73 You can use a keyboard map file (see
75 to map them to arbitrary keys, particularly
76 the functions in the range from 65 to 96
77 which are not used by default.

129 .Sh DRIVER CONFIGURATION
130 .Ss Kernel Configuration Options
131 The following kernel configuration options control the
134 .Bl -tag -width ATKBD_DFLT
135 .It Em ATKBD_DFLT_KEYMAP
136 This option sets the default, built-in keymap of the
138 driver to the named keymap.
142 .It Em KBD_DISABLE_KEYMAP_LOAD
143 The keymap can be modified by the
146 This option will disable this feature and prevent the user from
147 changing key assignment.
152 driver accepts the following driver flags.
153 They can be set either in
154 .Pa /boot/device.hints ,
155 or else from within the boot loader
159 .It bit 0 (FAIL_IF_NO_KBD)
162 driver will install even if a keyboard is not actually connected to the
164 This option prevents the driver from being installed in this situation.
166 When this option is given, the
168 driver will not reset the keyboard when initializing it.
169 It may be useful for laptop computers whose function keys
170 have special functions and these functions are forgotten when the
172 .It bit 2 (ALT_SCANCODESET)
173 Certain keyboards, such as those on some ThinkPad models, behave
174 like the old XT keyboard and require this option.
175 .It bit 3 (NO_PROBE_TEST)
176 When this option is given, the
178 driver will not test the keyboard port during the probe routine.
179 Some machines hang during boot when this test is performed.
185 driver requires the keyboard controller
187 Thus, the kernel configuration file should contain the following lines.
192 The following example shows how to set the default, built-in keymap
197 .Dl "options ATKBD_DFLT_KEYMAP"
198 .Dl "makeoptions ATKBD_DFLT_KEYMAP=jp.106"
201 In both cases, you also need to have following lines in
202 .Pa /boot/device.hints .
204 .Dl hint.atkbdc.0.at="isa"
205 .Dl hint.atkbdc.0.port="0x060"
