30.Dt ATKBD 4
31.Os
32.Sh NAME
33.Nm atkbd
34.Nd the AT keyboard interface
35.Sh SYNOPSIS
36.Cd "options ATKBD_DFLT_KEYMAP"
37.Cd "makeoptions ATKBD_DFLT_KEYMAP=_keymap_name_"
38.Cd "options KBD_DISABLE_KEYMAP_LOAD"
39.Cd "device atkbd0 at atkbdc? irq 1"
40.Sh DESCRIPTION
41The
42.Nm
43driver, together with the
44.Nm atkbdc
45driver, provides access to the AT 84 keyboard or the AT enhanced keyboard
46which is connected to the AT keyboard controller.
47.Pp
48This driver is required for the console drivers
49.Xr syscons 4
50and
51.Xr pcvt 4 .
52.Pp
53There can be only one
54.Nm
55device defined in the kernel configuration file.  This device also
56requires the
57.Nm atkbdc
58keyboard controller to be present.
59The
60.Em irq
61number must always be 1; there is no provision of changing the number.
62.Ss Function Keys
63The AT keyboard has a number of function keys.
64They are numbered as follows and can be associated with strings
65by the
66.Xr kbdcontrol 1
67command.

114See the man page for the

116command for how to assign a string to the function key.
117.Sh DRIVER CONFIGURATION
118.Ss Kernel Configuration Options
119The following kernel configuration options control the
120.Nm
121driver.
122.Bl -tag -width ATKBD_DFLT
123.It Em ATKBD_DFLT_KEYMAP
124This option sets the defauilt, built-in keymap of the
125.Nm
126driver to the named keymap.
127See
128.Sx EXAMPLES
129below.
130.It Em KBD_DISABLE_KEYMAP_LOAD
131The keymap can be modified by the
132.Xr kbdcontrol 1
133command.
134This option will disable this feature and prevent the user from
135changing key assignment.
136.El
137.Pp
138.Ss Driver Flags
139The
140.Nm
141driver accepts the following driver flags.  They can be set either in the
142kernel configuration file
143(see
144.Xr config 8 ) ,
145or else in the User Configuration Menu at boot time
146(see
147.Xr boot 8 ) .
148.Bl -tag -width FAIL
149.It bit 0 (FAIL_IF_NO_KBD)
150By default the
151.Nm
152driver will install even if a keyboard is not actually connected to the
153system.
154This option prevents the driver from being installed in this situation.
155.It bit 1 (NO_RESET)
156When this option is given, the
157.Nm
158driver will not reset the keyboard when initializing it.
159It may be useful for laptop computers whose function keys
160have special functions and these functions are forgotten when the
161keyboard is reset.
162.It bit 2 (ALT_SCANCODESET)
163Certain keyboards, such as those on some ThinkPad models, behave
164like the old XT keyboard and require this option.
165.El
166.\".Sh FILES
167.Sh EXAMPLES
168The
169.Nm
170driver requires the keyboard controller
171.Nm atkbdc .
172Thus, the kernel configuration file should contain the following lines.
173.Pp
174.Dl "device atkbdc0 at isa"
175.Dl "device atkbd0 at atkbdc? irq 1"
176.Pp
177The following example shows how to set the default, built-in keymap
178to
179.Pa jp.106.kbd .
180.Pp
181.Dl "options ATKBD_DFLT_KEYMAP"
182.Dl "makeoptions ATKBD_DFLT_KEYMAP=jp.106"
183.Dl "device atkbd0 at atkbdc? irq 1"
