This device also 57requires the 58.Nm atkbdc 59keyboard controller to be present. 60The 61.Em irq 62number must always be 1; there is no provision of changing the number. 63.Ss Function Keys 64The AT keyboard has a number of function keys. 65They are numbered as follows and can be associated with strings 66by the 67.Xr kbdcontrol 1 68command. 69.Pp 70.Bl -tag -width "Function Key Number" -compact -offset 71.It "Function Key number" 72Function Key 73.It "1, 2,...12" 74F1, F2,...

They can be set either in the 143kernel configuration file 144.Pq see Xr config 8 , 145or else in the User Configuration Menu at boot time 146.Pq see Xr boot 8 . 147.Bl -tag -width FAIL 148.It bit 0 (FAIL_IF_NO_KBD) 149By default the 150.Nm 151driver will install even if a keyboard is not actually connected to the 152system. 153This option prevents the driver from being installed in this situation. 154.It bit 1 (NO_RESET) 155When this option is given, the 156.Nm 157driver will not reset the keyboard when initializing it. 158It may be useful for laptop computers whose function keys 159have special functions and these functions are forgotten when the 160keyboard is reset. 161.It bit 2 (ALT_SCANCODESET) 162Certain keyboards, such as those on some ThinkPad models, behave 163like the old XT keyboard and require this option. 164.El 165.\".Sh FILES 166.Sh EXAMPLE 167The 168.Nm 169driver requires the keyboard controller 170.Nm atkbdc . 171Thus, the kernel configuration file should contain the following lines. 172.Pp 173.Dl "device atkbdc0 at isa" 174.Dl "device atkbd0 at atkbdc? irq 1" 175.Pp 176The following example shows how to set the default, built-in keymap 177to 178.Pa jp.106.kbd . 179.Pp 180.Dl "options ATKBD_DFLT_KEYMAP" 181.Dl "makeoptions ATKBD_DFLT_KEYMAP"=\&"jp.106\&" 182.Dl "device atkbd0 at atkbdc? irq 1" 183.Pp 184.\".Sh DIAGNOSTICS 185.\".Sh CAVEATS 186.\".Sh BUGS 187.Sh SEE ALSO 188.Xr kbdcontrol 1 , 189.Xr atkbdc 4 , 190.Xr pcvt 4 , 191.Xr psm 4 , 192.Xr syscons 4 , 193.Xr boot 8 , 194.Xr config 8 . 195.Sh HISTORY 196The 197.Nm 198driver first appeared in 199.Fx 3.1 . 200.Sh AUTHORS 201The 202.Nm 203driver was written by 204.An S�ren Schmidt Aq sos@FreeBSD.org 205and 206.An Kazutaka Yokota Aq yokota@FreeBSD.org . 207This manual page was written by 208.An Kazutaka Yokota . 209
