Fn + F11 clears the ESCD configuration information. If the Fn + F11 sequence is
pressed very early after powering the machine on (after you see the keyboard LEDs
blink, but before the video is initialized), CMOS memory will be invalidated. The
ESCD is cleared, the machine is reset and boots with the "162 - System Options Not
Set" message. This is a way to clear out configuration information, such as Windows
95's knowledge about a docking station. It may help clear up problems if the
configuration information had been corrupted. Timing of this keystroke sequence is
critical, as there is a very narrow window during which the keys will be recognized.
These keys are not documented to users.
