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.

Clear CMOS setting OFF ON ON

Keep CMOS setting ON ON OFF

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.

SPDIF/COMP Select: SPDIF_SEL

This jumper is for selecting between SPDIF and RCA (composite) video.
