1-2
Chapter 1: Product introduction
IEEE 1394 support (on 1394 models only)
The IEEE 1394 interfaces and the TI TSB43AB22 controller onboard
provide high-speed and flexible PC connectivity to a wide range of
peripherals and devices compliant to IEEE 1394a standards. The IEEE
1394 allows up to 400Mbps transfer rates through simple, low-cost, highbandwidth asynchronous (real-time) data interfacing between computers,
peripherals, and consumer electronic devices such as camcorders, VCRs,
printers,TVs, and digital cameras. See page 2-27.
USB 2.0 technology
The motherboard implements the new Universal Serial Bus (USB) 2.0
specification, extending the connection speed from 12 Mbps on USB 1.1
to a fast 480 Mbps on USB 2.0. The higher bandwidth of USB 2.0 allows
connection of devices such as high resolution video conferencing
cameras, next generation scanners and printers, and fast storage units.
USB 2.0 is backward compatible with USB 1.1. See page 2-25.
6-channel digital audio (on audio models only)
The RealTek ALC650, an 18-bit, full duplex AC ‘97 2.2 stereo audio
CODEC, is onboard to provide 6-channel audio capability. The ALC650
supports independent variable sampling rates and built-in 3D effects,
mono outputs, multiple stereo and mono inputs, and flexible mixing/gain/
mute functions for a complete integrated audio solution. A digital audio
connector is onboard to accommodate the bundled Sony/Philips Digital
Interface (S/PDIF) In/Out module. See page 2-23.
C.P.R. (CPU Parameter Recall)
The C.P.R. feature of the motherboard BIOS allows automatic re-setting to
the BIOS default settings in case the system hangs due to overclocking.
When the system hangs due to overclocking, C.P.R. eliminates the need to
open the system chassis and clear the RTC data. Simply shut down and
reboot the system, and BIOS automatically restores the CPU default
setting for each parameter.
ASUS EZ Plug™
This patented ASUS technology lets you use your existing power supply
rather than buying a new ATX 12V power supply. The ASUS EZ Plug™ is
a 4-pin auxiliary +12V connector mounted on the motherboard that
connects a regular 4-pin device power connector from the power supply.
This connector is necessary to provide the additional power required by
the P4 CPU. See page 2-23.
ASUS P4G8X series motherboard user guide
1-3
ASUS POST Reporter™
The motherboard offers a new exciting feature called the ASUS POST
Reporter™ to provide friendly voice messages and alerts during the
Power-On Self-Tests (POST). Through an added external speaker, you will
hear the messages informing you of the system boot status and causes of
boot errors, if any. The bundled Winbond Voice Editor software allows you
to customize the voice messages, and provides multi-language support.
See page 5-17.
ASUS MyLogo2™
This new feature present in the motherboard allows you to personalize and
add style to your system with customizable boot logos. See details on
page 5-10.
ASUS Multi-language BIOS
The multi-language BIOS allows you to select the language of your choice
from the available options. The localized BIOS menus allow you to
configure easier and faster. Visit the ASUS website for information on the
supported languages.
ASUS EZ Flash BIOS
With the ASUS EZ Flash, you can easily update the system BIOS even
before loading the operating system. No need to use a DOS-based utility
or boot from a floppy disk.
ASUS Q-Fan technology
The ASUS Q-Fan technology smartly adjusts the fan speeds according to
the system loading to ensure quiet, cool, and efficient operation.
CrashFree BIOS
This feature allows you to restore the original BIOS data from a floppy disk
in cases when the BIOS codes and data are corrupted. This protection
eliminates the need to buy a replacement ROM chip. See page 4-7.
BlueMagic PCI slot
The ASUS proprietary BlueMagic slot is onboard to support future ASUS
function cards that are also compliant to PCI specification.
1-4
Chapter 1: Product introduction
1.3.2 Value-added solutions
Overclocking
• C.P.R. (CPU Parameter Recall)
• adjustable CPU VCORE , and DDR memory and AGP voltages
• Stepless Frequency Selection (SFS) for fine-tuning system bus
frequency from 100MHz up to 400MHz at 1MHz increments
Concurrent PCI
This feature allows multiple PCI transfers from PCI master buses to the
memory and processor.
Temperature, fan, and voltage monitoring
The CPU temperature is monitored by the ASUS ASIC to prevent
overheating and damage. The system fan rotations per minute (RPM) is
monitored for timely failure detection. The system voltage levels are
monitored to ensure stable supply of current for critical components.
Dual function power switch
While the system is ON, pressing the power switch for less than 4 seconds
puts the system to sleep mode or to soft-off mode, depending on the BIOS
setting. Pressing the power switch for more than 4 seconds lets the
system enter the soft-off mode regardless of the BIOS setting.
ACPI ready
The Advanced Configuration power Interface (ACPI) provides more energy
saving features for operating systems that support OS Direct Power
Management (OSPM).
Auto fan off
The system fans power off automatically when the system is in sleep
mode. This feature reduces both power consumption and system noise.
Chassis intrusion detection
The motherboard supports chassis intrusion monitoring through the ASUS
ASIC. A chassis intrusion event is retained in CMOS for more protection.

P4G8X 184-Pin DDR DIMM Sockets
Notes on DDR technology
The DDR SDRAM technology evolved from the mainstream PC66, PC100,
PC133 memory known as Single Data Rate (SDR) SDRAM. DDR memory
however, has the ability to perform two data operations in one clock cycle,
thus providing twice the throughput of SDR memory.
A DDR DIMM has the same physical dimensions as an SDR DIMM, but it
has a 184-pin footprint compared to the 168-pin of the SDR DIMM. Also, a
DDR DIMM is single notched while an SDR DIMM is double notched.
Therefore, a DDR DIMM is not backward compatible with SDR, and should
be installed only in a socket specially designed for DDR DIMMs.
ASUS P4G8X series motherboard user guide

Important notes on memory configurations
1. Installing DDR DIMMs other than the recommended configurations
may cause memory sizing error or system boot failure. See Table 1
for the recommended configurations.
2. Install only identical (the same type and size) DDR DIMM pairs
using the recommended configurations.
3. Make sure that the memory frequency matches the CPU FSB
(Front Side Bus). Refer to Table 2 below.
4. Double-sided x16 DDR DIMMs are not supported on this

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

Connectors
This section describes and illustrates the internal connectors on the
motherboard.
Always connect ribbon cables with the red stripe to Pin 1 on the
connectors. Pin 1 is usually on the side closest to the power connector
on hard drives and CD-ROM drives, but may be on the opposite side
on floppy disk drives.
1. Hard disk activity LED (2-pin IDE_LED)
This connector supplies power to the hard disk activity LED. The read
or write activities of any device connected to the primary or secondary
IDE connector cause this LED to light up.
TIP: If the case-mounted LED does not
light, try reversing the 2-pin plug.

3. IDE connectors (40-1 pin PRI_IDE, SEC_IDE)
This connector supports the provided UltraDMA/100/66 IDE hard disk
ribbon cable. Connect the cable’s blue connector to the primary
(recommended) or secondary IDE connector, then connect the gray
connector to the UltraDMA/100/66 slave device (hard disk drive) and
the black connector to the UltraDMA/100/66 master device. It is
recommended that you connect non-UltraDMA/100/66 devices to the
secondary IDE connector. If you install two hard disks, you must
configure the second drive as a slave device by setting its jumper
accordingly. Refer to the hard disk documentation for the jumper
settings. BIOS supports specific device bootup. If you have more than
two UltraDMA/100/66 devices, purchase another UltraDMA/100/66
cable. You may configure two hard disks to be both master devices
with two ribbon cables – one for the primary IDE connector and
another for the secondary IDE connector.
1. Pin 20 on each IDE connector is removed to match the covered
hole on the UltraDMA cable connector. This prevents incorrect
orientation when you connect the cables.
2. The hole near the blue connector on the UltraDMA/100/66 cable is
intentional.

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).
Follow these steps to update the BIOS using ASUS EZ Flash.
1. Download the latest BIOS file from the ASUS website (see ASUS
contact information on page x). Save the file to a floppy disk.
Write down the BIOS file name on a piece of paper. You need to type
the exact BIOS file name at the EZ Flash screen.

4.1.2 Using AFLASH to update the BIOS
Creating a bootable disk
AFLASH.EXE is a Flash Memory Writer utility that updates the BIOS by
uploading a new BIOS file to the programmable flash ROM on the
motherboard. This file works only in DOS mode. To determine the BIOS
version of your motherboard, check the last four numbers of the code
displayed on the upper left-hand corner of your screen during bootup.
Larger numbers represent a newer BIOS file.
1. Type FORMAT A:/S at the DOS prompt to create a bootable system
disk. DO NOT copy AUTOEXEC.BAT and CONFIG.SYS to the disk.
2. Type COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your
CD-ROM drive) to copy AFLASH.EXE to the boot disk you created.
AFLASH works only in DOS mode. It 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.
3. Reboot the computer from the floppy disk.
BIOS setup must specify “Floppy” as the first item in the boot
sequence.
4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.
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.

Chapter 4: BIOS Setup
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!
1. Download an updated ASUS BIOS file from the Internet (WWW or
FTP) (see ASUS CONTACT INFORMATION on page x for details) and
save to the boot floppy disk you created earlier.
2. Boot from the floppy disk.
3. At the “A:\” prompt, type AFLASH and then press <Enter>.
4. At the Main Menu, type 2 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:\XXX-XX.XXX, then press <Enter>.
To cancel this operation, press <Enter>.
6. When prompted to confirm the BIOS update, press Y to start the
update.
ASUS P4G8X series motherboard user guide

7. The utility starts to program the new BIOS information into the Flash
ROM. The boot block is updated automatically only when necessary.
This minimizes the possibility of boot problems in case of update
failures. When the programming is done, the message “Flashed
Successfully” appears.
8. Follow the onscreen 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

4.1.3 CrashFree BIOS feature
The CrashFree BIOS feature allows you to boot the computer from a
floppy disk and update the BIOS in case the original BIOS fails or gets
corrupted.
1. You must have a bootable floppy disk ready before updating the
BIOS.
2. The bootable floppy disk could be the one that you created
following the procedure in section 4.1.2, and should contain the
AFLASH.EXE utility.
3. If the BIOS fails (ROM data or codes are corrupted), a message
appears during POST indicating the failure.
To update the BIOS:
1. Turn on the computer, and when prompted, place the bootable floppy
disk into the floppy drive, so that the computer boots from the floppy
disk.
2. Follow the BIOS update procedure in section “4.1.2 Using AFLASH to
update the BIOS.”

BIOS Setup program
This motherboard supports a programmable Flash ROM that you can
update using the provided utility described in section “4.1 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 menu-driven 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 exactly match what you see on your screen.

RAID 0/RAID 1 configurations
The motherboard includes the Silicon Image Sil3112A controller chipset
and two Serial ATA interfaces to support Redundant Array of Independent
Disks (RAID) configuration. This feature supports Serial ATA hard disks.
Use the SATARaid™ utility to configure a RAID set.
RAID 0 (called data striping) optimizes two identical hard disk drives to
read and write data in parallel, interleaved stacks. Two hard disks perform
the same work as a single drive but at a sustained data transfer rate,
double that of a single disk alone, thus improving data access and
storage.
RAID 1 (called data mirroring) copies and maintains an identical image of
data from one drive to a second drive. If one drive fails, the disk array
management software directs all applications to the surviving drive as it
contains a complete copy of the data in the other drive. This RAID
configuration provides data protection and increases fault tolerance to the
entire system.
5.4.1 Install the hard disks
The Sil3112A chipset supports Serial ATA hard disk drives. For optimal
performance, install identical drives of the same model and capacity when
creating a RAID set.
• If you are creating a RAID 0 (striping) array for perfomance, use two
new drives.
• If you are creating a RAID 1 (mirroring) array for protection, you can use
two new drives or use an existing drive and a new drive (the new drive
must be of the same size or larger than the existing drive). If you use two
drives of different sizes, the smaller capacity hard disk will be the base
storage size. For example, one hard disk has an 80GB storage capacity
and the other hard disk has 60GB storage capacity, the maximum
storage capacity for the RAID 1 set is 60GB.

Follow these steps to install the hard disks for RAID configuration.
1. Install the Serial ATA hard disks into the drive bays.
2. Connect one Serial ATA HDD to each Serial ATA connector, using
separate serial ATA cables.
4. Connect the power cable to the power connector on each drive.
5. Proceed to section 5.4.2 for the next procedure.
5.4.2 Creating and Deleting RAID sets
Creating and deleting RAID sets is a built-in function found in the BIOS.
The following sub-sections describes how to use the RAID Configuration
Utility.
Loading the RAID Configuration Utility
During POST, press <CTRL+S> or F4 to enter RAID configuration utility.
The following menu options will appear.

Creating RAID Sets
1. Select the option Create RAID Set.
2. Choose either a Striped or Mirrored RAID Set.
3. You may choose to auto-configure or manually configure the RAID Set.
For Striped Sets, you can change the chunk size. For Mirrored Sets,
you can specify the Source and Target drives, and create a Disk Copy.
What is a chunk? The chunk size is the “stripe” on each disk. It is the
unit of storage equivalent to one stripe on a RAID 0 set. Available
chunk sizes: [2] [4] [8] [16] [32] [64] [128]
When manually setting the chunk size for your RAID set, it is
recommended to use the smaller chunk size for server applications
and the larger chunk size for AV applications.
What is Disk Copy? If the disk assigned as the Source drive has been
previously partitioned and has data stored in it, and a second drive is
added, the data on the source drive can be copied to the Target drive.
This makes the Source and the Target drives identical. All subsequent
data will be written to both drives as a Mirrored set. However, if the
Source drive does not have data stored in it, there is no need for Disk
Copy.
4. When the utility prompts you with “Are You Sure? (Y/N)” before
completing the configuration, press “Y” to confirm or “N” to return to the
configuration options.
Deleting RAID Sets
1. To remove one or more RAID sets, select the option Delete RAID Set.
2. Select the RAID set to delete, and press “Y” when asked “Are You
Sure? (Y/N).”
Resolving Conflicts
When a RAID set is created, the metadata written to the disk includes
drive connection information (Primary Chanel, Secondary Chanel). If, after
a disk failure, the replacement disk was previously part of a RAID set (or
used in another system), it may have conflicting metadata, specifically in
the drive connection information. If so, this will a RAID set can neither be
created nor rebuilt. In order for the RAID set to function properly, this old
metadata must be first overwritten with the new metadata. To resolve this,
select the option Resolve Conflict so that the correct metadata (including
the correct drive connection information) may be written to the
replacement disk.
