1.9 Jumpers

1. Clear RTC RAM (CLRTC1)

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 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.

Except when clearing the RTC RAM, never remove the cap on CLRTC1 jumper

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

CLRTC

P4P800S-X

Normal

(Default)

Clear CMOS

P4P800S-X 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 default values.

2. USB device wake-up (3-pin USBPW1, USBPW2, USBPW3, USBPW4)

Set these jumpers to +5VSB to wake up the computer from S1 sleep mode

(CPU stopped, DRAM refreshed, system running in low power mode) using the

connected USB devices. Set to +5VSB to wake up from S3 sleep mode (no

power to CPU, DRAM in slow refresh, power supply in reduced power mode).

Both jumpers are set to pins 1-2 (+5VSB) by default because not all computers

have the appropriate power supply to support this feature.

The USBPW1 and USBPW2 jumpers are for the rear USB ports. The USBPW3

and USBPW4 jumpers are for the internal USB header that you can connect to

the front USB ports.

1. This feature requires a power supply that can provide at least 1A on the

+5VSB lead when these jumpers are set to +5VSB. Otherwise, the system

would not power up.

2. The total current consumed must NOT exceed the power supply capability

(+5VSB) whether under normal condition or in sleep mode.

3. The rear panel USB ports (Ports 1 to 4) do not support device wake-up

from S4 sleep mode.

2.2 BIOS Setup program

This motherboard supports a programmable firmware hub (FWH) 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 firmware hub 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 menu-

driven program, which means you can scroll through the various sub-menus and

make your selections from the available options using the navigation keys.

The default BIOS settings for this motherboard apply for most conditions to

ensure optimum performance. If the system becomes unstable after changing

any BIOS settings, load the default settings to ensure system compatibility and

stability. Select the Load Default Settings item under the Exit Menu. See

section “2.7 Exit Menu.”

The BIOS setup screens shown in this chapter are for reference purposes only,

and may not exactly match what you see on your screen.
