This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with manufacturers instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment to an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help.
The use of shielded cables for connection of the monitor to the graphics card is required to assure compliance with FCC regulations. Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the users authority to operate this equipment.

Safety information

Electrical safety
To prevent electrical shock hazard, disconnect the power cable from the electrical outlet before relocating the system. When adding or removing devices to or from the system, ensure that the power cables for the devices are unplugged before the signal cables are connected. If possible, disconnect all power cables from the existing system before you add a device. Before connecting or removing signal cables from the motherboard, ensure that all power cables are unplugged. Seek professional assistance before using an adpater or extension cord. These devices could interrupt the grounding circuit. Make sure that your power supply is set to the correct voltage in your area. If you are not sure about the voltage of the electrical outlet you are using, contact your local power company. If the power supply is broken, do not try to fix it by yourself. Contact a qualified service technician or your retailer.

1.7.2 Memory configurations
You may install 64MB, 128MB, 256MB, 512MB, and 1GB DDR DIMMs into the DIMM sockets using the memory configurations in this section.

Important notes

Installing DDR DIMMs other than the recommended configurations may cause memory sizing error or system boot failure. Use any of the recommended configurations in Table 1. Use the blue DIMM slots first. In Dual-channel configurations, install only identical (the same type and size) DDR DIMM pairs for each channel. Always install DIMMs with the same CAS latency, otherwise, the system may run in a lower frequency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor. See list of Qualified Vendors List on page 1-10. When all four sockets are populated with 1GB DIMMs (Total 4 GB), the system may detect only 3+ GB (a little less than 4 GB) due to the SouthBridge resource allocation. Three DDR DIMMs installed into any three memory sockets will function in single channel mode. Make sure that the memory frequency matches the CPU FSB. Refer to Table 2 for configurations.

Memory frequency/CPU FSB synchronization
This motherboard supports different memory frequencies depending on the CPU FSB (Front Side Bus) and the type of DDR DIMM.
CPU FSB 800 MHz 533 MHz 400 MHz DDR DIMM Type PC3200/PC2700/PC2100 PC2700/PC2100 PC2100 Memory Frequency 400/320*/266 MHz 333/266 MHz 266 MHz
*When using 800 MHz FSB CPU, PC2700 DDR DIMMs run only at 320MHz (not 333MHz) due to chipset limitation.

When the copy process is complete, the utility returns to the DOS prompt.
2.1.4 Using ASUS EZ Flash to update the BIOS
The ASUS EZ Flash feature allows you to easily update the BIOS without having to go through the long process of booting from a diskette and using a DOS-based utility. The EZ Flash is built-in the BIOS firmware so it is accessible by simply pressing <Alt + F2> during the Power-On Self Tests (POST).
To update the BIOS using ASUS EZ Flash:
1. Visit the ASUS website (www.asus.com) to download the latest BIOS file for your motherboard and rename the downloaded file as P4P800X.ROM. Save the BIOS file to a floppy disk. 2. Reboot the system. 3. To launch EZ Flash, press <Alt+F2> during POST to display the following.
User recovery requested. Starting BIOS recovery. Checking for floppy.
If there is no floppy disk in the drive, the error message Floppy not found! appears. If the correct BIOS file is not in the floppy disk, the error message Floppy not found! is displayed. Make sure to rename the downloaded BIOS file as P4P800X.ROM.
4. Insert the floppy disk that contains the BIOS file. If all the necessary files are found in the floppy disk, EZ Flash performs the BIOS update process and automatically reboots the system when done.
User recovery requested. Starting BIOS recovery. Checking for floppy. Floppy found! Reading file P4P800X.ROM. Completed. Start flashing. Flashed successfully. Rebooting.
2.1.5 Recovering the BIOS with CrashFree BIOS 2
The CrashFree BIOS 2 auto recovery tool allows you to restore BIOS from the motherboard support CD, or from a floppy disk that contains the BIOS file, in case the current BIOS on the motherboard fails or gets corrupted.
Prepare the support CD that came with the motherboard or a floppy disk that contains the motherboard BIOS before proceeding with the BIOS update process. If you have saved a copy of the original motherboard BIOS to a bootable floppy disk, you may also use this disk to restore the BIOS. See section 2.1.1 Creating a bootable floppy disk.
To recover the BIOS from a floppy disk:
1. Boot the system. 2. When a corrupted BIOS is detected, the following screen message appears.

Bad BIOS checksum. Starting BIOS recovery. Checking for floppy.
3. Insert a floppy disk that contains the original or the latest BIOS file for this motherboard. If all the necessary files are found in the floppy disk, the BIOS update process continues.
Make sure that the BIOS file in the floppy disk is renamed as P4P800X.ROM.
Bad BIOS checksum. Starting BIOS recovery. Checking for floppy. Floppy found! Reading file P4P800X.ROM. Completed. Start flashing.
DO NOT shut down or reset the system while updating the BIOS! Doing so may cause system boot failure!
2. When the BIOS update process is complete, reboot the system.
To recover the BIOS from the support CD:
If there is no floppy disk found in the drive, the system automatically checks the CD-ROM.
3. Place the support CD in the CD-ROM. The support CD contains the a working BIOS for this motherboard.
Bad BIOS checksum. Starting BIOS recovery. Checking for floppy. Floppy not found! Checking for CD-ROM. CD-ROM found. Reading file P4P800X.ROM. Completed. Start flashing. DO NOT shut down or reset the system while updating the BIOS! Doing so may cause system boot failure!
The recovered BIOS may not be the latest BIOS version for this motherboard. Visit ASUS website (www.asus.com) to download the latest BIOS file.

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 menudriven program, which means you can scroll through the various sub-menus and make your selections from the available options using the navigation keys.
