Chapter 2: Hardware information

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

default position. Removing the cap will cause system boot failure!

This jumper allows you to clear the  Real Time Clock (RTC) RAM in CMOS. 

You can clear the CMOS memory of date, time, and system setup parameters 

by erasing the CMOS RTC RAM data. The onboard button cell battery 

powers the RAM data in CMOS, which include system setup information such 

as system passwords.

 

To erase the RTC RAM:

 

1.  Turn OFF the computer and unplug the power cord.

 

2.  Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on  

 

pins 2-3 for about 5~10 seconds, then move the cap back to pins  1-2.

 

3.  Plug the power cord and turn ON the computer.

 

4.  Hold down the <Del> key during the boot process and enter BIOS setup  

 

to re-enter data.

If the steps above do not help, remove the onboard battery and move the 

jumper again to clear the CMOS RTC RAM data. After the CMOS clearance, 

reinstall the battery.
