UMPERS
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.

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.
