User manual

The EITX-3000 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 JUMPER

The onboard CMOS RAM stores system configuration data and

has an onboard battery power supply. To reset the CMOS settings,

set the jumper on pin 2 and 3 while the system is off. Return the

jumper to pin 1 and 2 afterwards. Setting the jumper while the

system is on will damage the mainboard.

Caution:

Except when clearing the RTC RAM, never remove the

CLEAR_CMOS jumper cap from the default position. Removing

the cap will cause system boot failure. Avoid clearing the CMOS

while the system is on; it will damage the mainboard.
