Jumpers

The mainboard provides jumpers for setting some mainboard functions.

This section will explain how to change the settings of the mainboard

functions using the jumpers.

Clear CMOS Connector: CLEAR_CMOS1

The onboard CMOS RAM stores system configuration data and has an

onboard battery power supply. To reset the CMOS settings, set the

jumper on pins 1 and 2 while the system is off. Return the jumper to

pins 2 and 3 afterwards. Setting the jumper while the system is on will

damage the mainboard.

Caution:

Except when clearing the RTC RAM, never remove the cap on

CLEAR_CMOS jumper default position. Removing the cap will cause

system boot failure. Avoid clearing the CMOS while the system is on;

it will damage the mainboard.

Voltage Selector for COM Connectors: JCOMV2

This VCC selector is to determine the input voltage of each COM

connector.
