options PCKBD_LAYOUT=XXX
The pckbd driver supports a number of
    different key mappings which can be chosen from with the kernel option
    PCKBD_LAYOUT at compile time or with the utility
    wsconsctl(8) (variable:
    “encoding”) at runtime. Other mappings can be used if the
    whole keymap is replaced by means of
    wsconsctl(8).
Because PC keyboard hardware doesn't contain a beeper, requests for “keyboard beeps” cannot be handled directly. On alpha and i386 a helper device attached to the pcppi(4) driver allows the use of the standard ISA speaker for this purpose. On acorn32, acorn32/vidcaudio(4) performs this function.
