1.9 Jumpers
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 RAM data in CMOS, that include
system setup information such as system passwords, is powered by the
onboard button cell battery.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 2-3 (default) to pins 1-2. Keep the cap on
pins 1-2 for about 5~10 seconds, then move the cap back to pins 2-3.
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.
Except when clearing the RTC RAM, never remove the cap on the jumper
default position. Removing the cap will cause system boot failure!
P4BP-MX 2.0
P4BP-MX 2.0 Clear RTC RAM
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 BIOS can automatically reset
parameter settings to its previous values.

2.2 BIOS Setup program
This motherboard supports a programmable firmware hub (FHW) chip that you can
update using the provided utility described in section “2.1 Managing and updating
your BIOS.”
Use the BIOS Setup program when you are installing a motherboard, reconfiguring
your system, or prompted to “Run Setup”. This section explains how to configure
your system using this utility.
Even if you are not prompted to use the Setup program, you may want to change
the configuration of your computer in the future. For example, you may want to
enable the security password feature or change the power management settings.
This requires you to reconfigure your system using the BIOS Setup program so
that the computer can recognize these changes and record them in the CMOS
RAM of the firmware hub.
The FWH chip on the motherboard stores the Setup utility. When you start up the
computer, the system provides you with the opportunity to run this program. Press
<Delete> during the Power-On Self Test (POST) to enter the Setup utility.
Otherwise, POST continues with its test routines.
If you wish to enter Setup after POST, restart the system by pressing <Ctrl> +
<Alt> + <Delete>, or by pressing the reset button on the system chassis. You can
also restart by turning the system off and then back on. Do this last option only if
the first two failed.
The Setup program is designed to make it as easy to use as possible. It is a menudriven program, which means you can scroll through the various sub-menus and
make your selections from the available options using the navigation keys.
If the system becomes unstable after changing any BIOS settings, load the
default settings to ensure system stability. Select the Load Optimized Settings
item under the Exit Menu. See section “2.7 Exit menu.”
