2.6 Jumper 1. Clear RTC RAM (CLRTC) 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. Remove the onboard battery. 3. 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. 4. Reinstall the battery. 5. Plug the power cord and turn ON the computer. 6. Hold down the key during the boot process and enter BIOS setup to re-enter data. Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure! P5WD2 ® P5WD2 Clear RTC RAM CLRTC 1 2 Normal (Default) 2 3 Clear CMOS You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the C.P.R. (CPU Parameter Recall) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values. 2-26 Chapter 2: Hardware information

3.
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.
4.
Reinstall the battery.
5.
Plug the power cord and turn ON the computer.
6.
Hold down the <Del> key during the boot process and enter BIOS
setup to re-enter data.
You do not need to clear the RTC when the system hangs due to
overclocking. For system failure due to overclocking, use the C.P.R. (CPU
Parameter Recall) feature. Shut down and reboot the system so the BIOS
can automatically reset parameter settings to default values.
Except when clearing the RTC RAM, never remove the cap on CLRTC
jumper default position. Removing the cap will cause system boot failure!
