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: CLEAR_CMOS

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 2 and 3 while the system is off. Return the jumper to pins 1 and 2

afterwards. Setting the jumper while the system is on will damage the

mainboard.

Normal Operation ON ON OFF

Clear CMOS setting OFF ON ON

WARNING: Except when clearing the RTC RAM, never remove the

cap on CLEAR_CMOS1 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.

Inverter Selector: IVDD_SEL

IVDD is the VCC selector jumper to determine the input

voltage of the panel inverter for panel’s back-light.
