When using PCI cards on shared slots, ensure that the drivers support “Share
IRQ” or that the cards do not need IRQ assignments. Otherwise, conflicts will
arise between the two PCI groups, making the system unstable and the card
inoperable.

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.
P4S800-MX
Except when clearing the RTC RAM, never remove the cap on CLRTC1 jumper
default position. Removing the cap will cause system boot failure!

2. USB device wake-up (3-pin USBPW12, USBPW34, USBPW56)
Set these jumpers to +5V 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 (+5V) by default because not all computers
have the appropriate power supply to support this feature.
The USBPW_12 and USBPW_34 jumpers are for the rear USB ports. The
USBPW_56 jumper is 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.

BIOS Setup program
This motherboard supports a programmable Flash EEPROM 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 make changes to 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 Flash ROM.
The Flash ROM 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 among the predetermined choices.
Because the BIOS software is constantly being updated, the following BIOS
setup screens and descriptions are for reference purposes only, and may not

before exiting. Pressing <Enter> saves the changes while exiting.

Setup program. If you made changes to fields other than system date, system time,
and password, the BIOS asks for a confirmation before exiting.

This option allows you to load the default values for each of the parameters on the
Setup menus. When you select this option or if you press <F5>, a confirmation window
appears. Select [Yes] to load default values. Select Exit & Save Changes or make
other changes before saving the values to the non-volatile RAM.
Discard Changes
This option allows you to discard the selections you made and restore the previously
saved values. After selecting this option, a confirmation appears. Select [Yes] to
discard any changes and load the previously saved values.
Save Changes
This option saves your selections without exiting the Setup program. You can then
return to other menus and make further changes. After you select this option, a
confirmation window appears. Select [Yes] to save changes to the non-volatile RAM.
