This jumper lets you erase the system setup settings that are stored in
CMOS memory. You might need to erase this data if incorrect settings
are preventing your system from operating. To clear the CMOS memory,
turn off the system, disconnect the power cable from the mainboard, and
short the appropriate pins for a few seconds.
