Clearing the CMOS settings

The Clear RTC RAM (3-pin CLRTC) jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. It also allows clearing of date, time, and system setup parameter memories in CMOS, by erasing the RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, including system setup information.

CAUTION:

Do not change any jumper setting while the computer is on. Damage to the motherboard can result.

1. Turn off the PC and unplug the power cord.
2. Move the CLRTC jumper cap from pins 1-2 (normal) to pins 2-3 (clear CMOS).
   
   
3. Keep the CLRTC jumper cap on pins 2-3 for 5 to 10 seconds, then move it back to pins 1-2.
4. Plug in the power cord and turn on the PC.
5. Press F1 as the PC starts to enter BIOS setup and change BIOS settings.

Clearing the BIOS password

The BIOS password protects the BIOS from undesired changes (password checking is disabled by default). If password checking is enabled, and you need to disable it, use the following steps:

1. Turn off the PC and unplug the power cord.
2. Move the CLRPWD jumper cap from pins 1-2 to pins 2-3.
   
   
3. Press F1 as the PC starts to enter the BIOS setup .
4. Clear or reset the BIOS password.
   
5. Save the BIOS settings and turn off the PC.
   
6. If desired, reactivate BIOS password checking by returning the CLRPWD jumper cap to pins 1-2.
