143.Ss Driver Flags
144The
145.Nm
146driver accepts the following driver flags.
147They can be set either in
148.Pa /boot/device.hints ,
149or else from within the boot loader
150(see
151.Xr loader 8 ) .
152.Bl -tag -width FAIL
153.It bit 0 (FAIL_IF_NO_KBD)
154By default the
155.Nm
156driver will install even if a keyboard is not actually connected to the

171.Sh EXAMPLES
172The
173.Nm
174driver requires the keyboard controller
175.Nm atkbdc .
176Thus, the kernel configuration file should contain the following lines.
177.Pp
178.Dl "device atkbdc"
179.Dl "device atkbd"
180.Pp
181The following example shows how to set the default, built-in keymap
182to
183.Pa jp.106.kbd .
184.Pp
185.Dl "device atkbdc"
186.Dl "options ATKBD_DFLT_KEYMAP"
187.Dl "makeoptions ATKBD_DFLT_KEYMAP=jp.106"
188.Dl "device atkbd"
189.Pp
190In both cases, you also need to have following lines in
191.Pa /boot/device.hints .
192.Pp
193.Dl hint.atkbdc.0.at="isa"
194.Dl hint.atkbdc.0.port="0x060"
