Setting Jumper Switches
Jumpers are sets of pins connected together with caps. Jumper caps
change the way of mainboard’s operation by changing the
electronic circuits on the mainboard. If a jumper cap connects two
pins, we say those pins are SHORT; if the cap is removed, they are
OPEN.
Jumper JBAT1: Clear CMOS Memory
This jumper is to clear the contents of CMOS memory. You may
need to clear the CMOS memory if the settings in the Setup Utility
are incorrect that prevents your mainboard from operating. To clear
the CMOS memory, disconnect all the power cables from the
mainboard and then move the jumper cap into the CLEAR setting
for a few seconds.
