This can be done in 98one of the following two ways. 99.Pp 100Run the following command as a part of system initialization: 101.Bd -literal -offset indent 102kbdcontrol -k /dev/kbd0 < /dev/ttyv0 > /dev/null 103.Ed 104.Pp 105(Note that as the USB keyboard is the only keyboard, it is accessed as 106/dev/kbd0) or otherwise tell the console driver to periodically look for a 107keyboard by setting a flag in the kernel configuration file: 108.Bd -literal -offset indent 109device sc0 at isa? flags 0x100 110.Ed 111.Pp 112With the above flag, the console driver will try to detect any 113keyboard in the system if it didn't detect one while it was 114initialized at boot time. 115.Sh DRIVER CONFIGURATION 116.Bd -literal -offset indent 117options "KBD_INSTALL_CDEV" 118.Ed 119.Pp 120Make the keyboards available through a character device in /dev 121.Bd -literal -offset indent 122options "UKBD_DFLT_KEYMAP" 123makeoptions "UKBD_DFLT_KEYMAP=fr.iso" 124.Ed 125.Pp 126The above lines will put the French ISO keymap in the ukbd driver. 127You can specify any keymap in /usr/share/syscons/keymaps with this 128option. 129.Bd -literal -offset indent 130options "KBD_DISABLE_KEYMAP_LOADING" 131.Ed 132.Pp 133Don't allow the user to change the keymap.
