Clear CMOS: is used to erase all customised BIOS settings located in
the CMOS RAM storage. If the board has a booting problem or is
unstabile, then Clearing CMOS by moving the Jumper from default
position to the Clear CMOS position for approx. 10 sec. might solve
the problem.
Audio Short Circuit Test: is only used in manufacturing test. No
jumper should be installed.
Warning: Don't leave the Clear CMOS jumper in position 1-2,
otherwise if power is disconnected, the battery will fully
deplete within a few weeks.
