Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.
1. 2. Unplug the power cord from the wall socket before touching any component. Use a grounded wrist strap or touch a safely grounded object or to a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity. Hold components by the edges to avoid touching the ICs on them. Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component. Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.

3. 4. 5.

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!

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. The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode. USBPW12 USBPW34
P4S800-MX USB Device Wake Up
3. Keyboard power (3-pin KBPWR1) This jumper allows you to enable or disable the keyboard wake-up feature. Set this jumper to pins 2-3 (+5VSB) if you wish to wake up the computer when you press a key on the keyboard (the default is the Space Bar). This feature requires an ATX power supply that can supply at least 1A on the +5VSB lead, and a corresponding setting in the BIOS (see 2.5.5 APM Configuration).

AFLASH is a Flash Memory Writer utility that allows you to update the BIOS using a bootable floppy disk, or copy the original motherboard BIOS. This utility only works in DOS mode.
Copying the original motherboard BIOS
To copy the original motherboard BIOS file: 1. Copy the AFLASH utility from the support CD to the boot disk you created.
AFLASH does not work in the DOS prompt within Windows, and does not work with certain memory drivers that may be loaded when you boot from the hard drive. It is recommended that you reboot using a floppy disk.
2. Reboot the computer from the floppy disk.
BIOS setup must specify Floppy as the first item in the boot sequence.
3. In DOS prompt, type AFLASH, then press <Enter> to run AFLASH. 4. Select 1. Save Current BIOS to File, then press <Enter>. The Save Current BIOS To File screen appears.
If the word unknown appears after Flash Memory, the memory chip is either not programmable or is not supported by the ACPI BIOS and therefore, cannot be programmed by the Flash Memory Writer utility.
5. Type a filename and the path, for example, A:\XXX-XX.XXX, then press <Enter>.

Updating the BIOS

Update the BIOS only if you have problems with the motherboard and you are sure that the new BIOS revision will solve your problems. Careless updating may result to more problems with the motherboard!
To update the BIOS: 1. Download an updated BIOS file from the ASUS website (www.asus.com) and save the file to the bootable floppy disk you earlier. 2. Reboot the computer from the floppy disk. 3. In DOS prompt, type AFLASH, then press <Enter> to run AFLASH. 4. Select 2. Update BIOS including Boot Block and ESCD, then press <Enter>. The Update BIOS Including Boot Block and ESCD screen appears. 5. Type the filename of your new BIOS and the path, for example, A:\P4S800MX.BIN, then press <Enter>. To cancel this operation, press <Enter>. 6. When prompted, press Y to start the update.
7. The utility starts updating the BIOS. The boot block is automatically updated only when necessary. This minimizes the possibility of boot problems in case of update failures. When updating is done, the message Flashed Successfully appears.
8. Follow the screen instructions to continue.

If you encounter problems while updating the new BIOS, DO NOT turn off the system because this may cause boot problems. Just repeat the process, and if the problem persists, load the original BIOS file you saved to the boot disk. If the Flash Memory Writer utility is not able to successfully update a complete BIOS file, the system may not boot. If this happens, call the ASUS Technical Support for assistance.
2.1.4 Recovering the BIOS with CrashFree BIOS
