35.Sh SYNOPSIS

45.Sh DESCRIPTION
46The
47.Nm
48driver, together with the
49.Nm atkbdc
50driver, provides access to the AT 84 keyboard or the AT enhanced keyboard
51which is connected to the AT keyboard controller.
52.Pp
53This driver is required for the console driver
54.Xr syscons 4 .
55.Pp
56There can be only one
57.Nm
58device defined in the kernel configuration file.
59This device also requires the
60.Nm atkbdc
61keyboard controller to be present.
62The
63.Em irq
64number must always be 1; there is no provision of changing the number.
65.Ss Function Keys
66The AT keyboard has a number of function keys.
67They are numbered as follows and can be associated with strings
68by the
69.Xr kbdcontrol 1
70command.
71You can use a keyboard map file (see
72.Xr kbdmap 5 )
73to map them to arbitrary keys, particularly
74the functions in the range from 65 to 96
75which are not used by default.

124See the man page for the

127.Sh DRIVER CONFIGURATION
128.Ss Kernel Configuration Options
129The following kernel configuration options control the
130.Nm
131driver.
132.Bl -tag -width ATKBD_DFLT
133.It Em ATKBD_DFLT_KEYMAP
134This option sets the default, built-in keymap of the
135.Nm
136driver to the named keymap.
137See
138.Sx EXAMPLES
139below.
140.It Em KBD_DISABLE_KEYMAP_LOAD
141The keymap can be modified by the
142.Xr kbdcontrol 1
143command.
144This option will disable this feature and prevent the user from
145changing key assignment.
146.El
147.Pp
148.Ss Driver Flags
149The
150.Nm
151driver accepts the following driver flags.
152They can be set either in
153.Pa /boot/device.hints ,
154or else from within the boot loader
155(see
156.Xr loader 8 ) .
157.Bl -tag -width FAIL
158.It bit 0 (FAIL_IF_NO_KBD)
159By default the
160.Nm
161driver will install even if a keyboard is not actually connected to the
162system.
163This option prevents the driver from being installed in this situation.
164.It bit 1 (NO_RESET)
165When this option is given, the
166.Nm
167driver will not reset the keyboard when initializing it.
168It may be useful for laptop computers whose function keys
169have special functions and these functions are forgotten when the
170keyboard is reset.
171.It bit 2 (ALT_SCANCODESET)
172Certain keyboards, such as those on some ThinkPad models, behave
173like the old XT keyboard and require this option.
174.It bit 3 (NO_PROBE_TEST)
175When this option is given, the
176.Nm
177driver will not test the keyboard port during the probe routine.
178Some machines hang during boot when this test is performed.
179.El
180.\".Sh FILES
181.Sh EXAMPLES
182The
183.Nm
184driver requires the keyboard controller
185.Nm atkbdc .
186Thus, the kernel configuration file should contain the following lines.
187.Pp
188.Dl "device atkbdc"
189.Dl "device atkbd"
190.Pp
191The following example shows how to set the default, built-in keymap
192to
193.Pa jp.106.kbd .
194.Pp
195.Dl "device atkbdc"
196.Dl "options ATKBD_DFLT_KEYMAP"
197.Dl "makeoptions ATKBD_DFLT_KEYMAP=jp.106"
198.Dl "device atkbd"
199.Pp
200In both cases, you also need to have following lines in
201.Pa /boot/device.hints .
202.Pp
203.Dl hint.atkbdc.0.at="isa"
204.Dl hint.atkbdc.0.port="0x060"
205.Dl hint.atkbd.0.at="atkbdc"
206.Dl hint.atkbd.0.irq="1"
