Setting Jumper Switches
Jumpers are sets of pins which can be connected together with
jumper caps. The jumper caps change the way the mainboard
operates by changing the electronic circuits on the mainboard. If a
jumper cap connects two pins, we say the pins are SHORT. If a
jumper cap is removed from two pins, the pins are OPEN.
Jumper JP1: Clear CMOS Memory
This jumper can clear the contents of the CMOS memory. You may
need to clear the CMOS memory if the settings in the Setup Utility
are incorrect and prevent 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.
