Chapter 1: Product introduction
1.3 Special features
1.3.1 Product highlights
Latest processor technology
The motherboard supports the latest Intel® Pentium® 4 or Celeron processor via a
478-pin surface mount ZIF socket. The Pentium 4 processor with 512KB L2 cache on
0.13 micron processor includes a 800*/533/400 MHz system bus, Intel® Hyper-
Threading Technology and the FMB2 power design that allows up to 3.06+ GHz
core frequencies for up to 6.4GB/s data transfer rates. (* Overclocking mode) See
page 1-8.
Integrated 10/100 LAN
The onboard LAN controller is a highly integrated Fast Ethernet controller. It is
enhanced with an ACPI management function to provide efficient power
management for advanced operating systems. See page 1-16.
Extreme Overclocking
The motherboard offers robust overclocking options to maximize your system
performance. Overclocking features include: the SFS (Stepless Frequency
Selection) feature, an adjustable FSB/DDR ratio and the ASUS C.P.R. (CPU
Parameter Recall).
6 USB 2.0 ports
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 1-19.
6-channel audio
The ADI AD1888 SoundMAX AC ‘97 audio CODEC is onboard to provide 6-
channel audio playback for 5.1 surround sound, over 90dB dynamic range, and
stereo Mic PREAMP. See pages 1-16, 3-3.
S/PDIF out
The motherboard supports S/PDIF out function turns your computer into a high-
end entertainment system with digital connectivity to powerful sound systems. See
page 1-16, 3-3.

1.3.2 Unique ASUS features
CrashFree BIOS 2
This feature allows you to restore the original BIOS data from a floppy disk or
support CD in case when the BIOS codes and data are corrupted. This protection
eliminates the need to buy a replacement ROM chip. Page 2-6.
ASUS MyLogo™
This new feature present in the motherboard allows you to personalize and add
style to your system with customizable boot logos. To use the MyLogo feature,
enable the Quick Boot item in the BIOS. See page 3-4.
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’s previous setting for each parameter. See
page 1-14.
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. See page 2-5.

Chapter 1: Product introduction
1.4 Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component.
2. 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.
3. Hold components by the edges to avoid touching the ICs on them.
4. Whenever you uninstall any component, place it on a grounded antistatic
pad or in the bag that came with the component.
5. 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.
Onboard LED
The motherboad comes with a stand-by power LED. When lit, the green LED
indicates that the system is ON, in sleep mode, or in soft-off mode, a reminder that
you should shut down the system and unplug the power cable before removing or
plugging in any motherboard component. The illustration below shows the location
of the onboard LED.
