Always On: is PT not supported.
(None): Not mounted on final version of board. Only mounted on Early Field Test versions of KTA70M.
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.
