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" 184.Pp 185.\".Sh DIAGNOSTICS 186.\".Sh CAVEATS 187.\".Sh BUGS 188.Sh SEE ALSO 189.Xr kbdcontrol 1 , 190.Xr atkbdc 4 , 191.Xr pcvt 4 , 192.Xr psm 4 , 193.Xr syscons 4 , 194.Xr boot 8 , 195.Xr config 8 196.Sh HISTORY 197The 198.Nm 199driver first appeared in 200.Fx 3.1 . 201.Sh AUTHORS 202.An -nosplit 203The 204.Nm 205driver was written by 206.An S\(/oren Schmidt Aq sos@FreeBSD.org 207and 208.An Kazutaka Yokota Aq yokota@FreeBSD.org . 209This manual page was written by 210.An Kazutaka Yokota . 211
