43 driver, together with the
45 driver, provides access to the AT 84 keyboard or the AT enhanced keyboard
46 which is connected to the AT keyboard controller.
48 This driver is required for the
54 device defined in the kernel configuration file. This device also
57 keyboard controller to be present.
60 number must always be 1; there is no provision of changing the number.
62 The AT keyboard has a number of function keys.
63 They are numbered as follows and can be associated with strings
68 .Bl -tag -width "Function Key Number" -compact
69 .It "Function Key number"
74 Shift+F1, Shift+F2,... Shift+F12
76 Ctl+F1, Ctl+F2,... Ctl+F12
78 Shift+Ctl+F1, Shift+Ctl+F2,... Shift+Ctl+F12

82 Up Arrow and Numpad 8 (without NumLock)
84 Page Up and Numpad 9 (without NumLock)

90 Numpad 5 (without NumLock)
92 Right Arrow and Numpad 6 (without NumLock)

98 Down Arrow and Numpad 2 (without NumLock)
100 Page Down and Numpad 3 (without NumLock)
102 Ins and Numpad 0 (without NumLock)
113 See the man page for the
115 command for how to assign a string to the function key.
116 .Sh DRIVER CONFIGURATION
117 .Ss Kernel Configuration Options
118 The following kernel configuration options control the
121 .Bl -tag -width ATKBD_DFLT
122 .It Em ATKBD_DFLT_KEYMAP
123 This option sets the default, built-in keymap of the
125 driver to the named keymap.
129 .It Em KBD_DISABLE_KEYMAP_LOAD
130 The keymap can be modified by the
133 This option will disable this feature and prevent the user from
134 changing key assignment.
139 driver accepts the following driver flags in the kernel configuration file.
141 .It bit 0 (FAIL_IF_NO_KBD)
144 driver will install even if a keyboard is not actually connected to the
146 This option prevents the driver from being installed in this situation.
148 When this option is given, the
150 driver will not reset the keyboard when initializing it.
151 It may be useful for laptop computers whose function keys
152 have special functions and these functions are forgotten when the
154 .It bit 2 (ALT_SCANCODESET)
155 Certain keyboards, such as those on some ThinkPad models, behave
156 like the old XT keyboard and require this option.
162 driver requires the keyboard controller
164 Thus, the kernel configuration file should contain the following lines.
166 .D1 Cd "device atkbdc0 at isa"
167 .D1 Cd "device atkbd0 at atkbdc? irq 1"
169 The following example shows how to set the default, built-in keymap
173 .D1 Cd "options ATKBD_DFLT_KEYMAP"
174 .D1 Cd "makeoptions ATKBD_DFLT_KEYMAP=jp.106"
