Onboard Audio Features
• Supports Microsoft®DirectSound/DirectSound 3D
• AC’97 supported with full duplex, independent sample rate
converter for audio recording and playback
• S/PDIF-in/out compressed digital output
• 6-channel audio output via software
S/PDIF
S/PDIF is a standard audio file transfer format that transfers digital
audio signals to a device without having to be converted first to an
analog format. This prevents the quality of the audio signal from
degrading whenever it is converted to analog. S/PDIF is usually
found on digital audio equipment such as a DAT machine or audio
processing device.The S/PDIF connector on the system board sends
surround sound and 3D audio signal outputs to amplifiers and
speakers and to digital recording devices like CD recorders.
6-channel Audio
The audio jacks at the rear panel will support 6-channel audio only
when the audio utility is configured to support this function.The mic-
in at the rear will be disabled. Use the front audio’s mic-in jack.
Onboard LAN Features
• Integrated LAN controller
• Integrated IEEE 802.3, 10BASE-T and 100BASE-TX compatible
PHY
• 32-bit PCI master interface
• Integrated power management functions
• Full duplex support at both 10 and 100 Mbps

• Supports ATAPI CD-ROM, LS-120 and ZIP
IrDA Interface
The system board is equipped with an IrDA connector for wireless
connectivity between your computer and peripheral devices. The
IRDA (Infrared Data Association) specification supports data
transfers of 115K baud at a distance of 1 meter.
USB Ports
The system board supports USB 2.0 and USB 1.1. USB 1.1
supports 12Mb/second bandwidth while USB 2.0 supports 480Mb/
second bandwidth providing a marked improvement in device trans-
fer speeds between your computer and a wide range of simultane-
ously accessible external Plug and Play peripherals.
BIOS
• Award BIOS, Windows®98/2000/ME/XP Plug and Play
compatible
• Supports SCSI sequential boot-up
• Supports DMI 2.0 function
• 4Mbit flash memory
Desktop Management Interface (DMI)
The system board comes with a DMI 2.0 built into the BIOS. The
DMI utility in the BIOS automatically records various information
about your system configuration and stores these information in the
DMI pool, which is a part of the system board's Plug and Play
BIOS. DMI, along with the appropriately networked software, is
designed to make inventory, maintenance and troubleshooting of
computer systems easier. Refer to chapter 4 for instructions on using
the DMI utility.

1.1.2 Intelligence
Dual Function Power Button
Depending on the setting in the “Soft-Off By PWRBTN” field of the
Power Management Setup, this switch will allow the system to enter
the Soft-Off or Suspend mode.

Introduction

12
Wake-On-Ring
This feature allows the system that is in the Suspend mode or Soft
Power Off mode to wake-up/power-on to respond to calls coming
from an external modem or respond to calls from a modem PCI
card that uses the PCI PME (Power Management Event) signal to
remotely wake up the PC.
Important:
If you are using a modem add-in card, the 5VSB power source
of your power supply must support ≥ 720mA.
Wake-On-LAN
This feature allows the network to remotely wake up a Soft Power
Down (Soft-Off) PC. It is supported via the onboard LAN port
and a PCI LAN card that uses the PCI PME (Power Management
Event) signal. However, if your system is in the Suspend mode, you
can power-on the system only through an IRQ or DMA interrupt.
Important:
The 5VSB power source of your power supply must support
≥ 720mA.
Wake-On-PS/2 Keyboard
This function allows you to use the PS/2 keyboard to wake up the
system from the S5 state.
Important:
The 5VSB power source of your power supply must support
≥ 720mA.

Introduction
13
Wake-On-USB Keyboard/Mouse
This function allows you to use a USB keyboard or USB mouse to
wake up a system from the S3 (STR - Suspend To RAM) state.
Important:
• If you are using the Wake-On-USB Keyboard/Mouse
function for 2 USB ports, the 5VSB power source of your
power supply must support ≥ 1.5A.
• If you are using the Wake-On-USB Keyboard/Mouse func-
tion for 3 or more USB ports, the 5VSB power source of
your power supply must support ≥ 2A.
RTCTimer to Power-on the System
The RTC installed on the system board allows your system to auto-
matically power-on on the set date and time.
ACPI STR
The system board is designed to meet the ACPI (Advanced Con-
figuration and Power Interface) specification. ACPI has energy saving
features that enables PCs to implement Power Management and
Plug-and-Play with operating systems that support OS Direct Power
Management. Currently, only Windows®®
®®
®98/2000/ME/XP supports
the ACPI function. ACPI when enabled in the Power Management
Setup will allow you to use the Suspend to RAM function.
With the Suspend to RAM function enabled, you can power-off the
system at once by pressing the power button or selecting “Standby”
when you shut down Windows®®
®®
®98/2000/ME/XP without having to
go through the sometimes tiresome process of closing files,
applications and operating system. This is because the system is
capable of storing all programs and data files during the entire
operating session into RAM (Random Access Memory) when it
powers-off.The operating session will resume exactly where you left
off the next time you power-on the system.
Important:
The 5VSB power source of your power supply must support
≥ 1A.

Introduction

AC Power Failure Recovery
When power returns after an AC power failure, you may choose to
either power-on the system manually, let the system power-on
automatically or return to the state where you left off before power
failure occurs.
Virus Protection
Most viruses today destroy data stored in hard drives. The system
board is designed to protect the boot sector and partition table of
your hard disk drive.
1.2 Hyper-Threading Technology Functionality
Requirements
Enabling the functionality of Hyper-Threading Technology for your
computer system requires ALL of the following platforms.
Components:
• CPU - an Intel®Pentium®4 Processor with HT Technology
• Chipset - an Intel®chipset that supports HT Technology
• BIOS - a BIOS that supports HT Technology and has it enabled
• OS - an operating system that includes optimizations for HT
Technology
Refer to Appendix A for information about enabling the functionality
of the Hyper-Threading Technology. For more information on Hyper-
Threading Technology, go to: www.intel.com/info/hyperthreading.

2.2 System Memory
Warning:
Electrostatic discharge (ESD) can damage your system board, proces-
sor, disk drives, add-in boards, and other components. Perform the
upgrade instruction procedures described at an ESD workstation only.
If such a station is not available, you can provide some ESD protection
by wearing an antistatic wrist strap and attaching it to a metal part
of the system chassis. If a wrist strap is unavailable, establish and
maintain contact with the system chassis throughout any procedures
requiring ESD protection.
The system board is equipped with two 184-pin DDR DIMM
sockets. DDR (Double Data Rate) is a type of SDRAM that dou-
bles the data rate through reading and writing at both the rising
and falling edge of each clock. This effectively doubles the speed
of operation therefore providing two times faster data transfer.
Refer to chapter 1 (System Memory section) for detailed specifi-
cation of the memory supported by the system board.

Hardware Installation
2.2.1 Installing the DIM Module
A DIM module simply snaps into a DIMM socket on the system
board. Pin 1 of the DIM module must correspond with Pin 1 of
the socket.
1. Pull the “tabs” which are at the ends of the socket to the
side.
2. Position the DIMM above the socket with the “notch” in the
module aligned with the “key” on the socket.
3. Seat the module vertically into the socket. Make sure it is
completely seated. The tabs will hold the DIMM in place.

2.3 CPU
2.3.1 Overview
The system board is equipped with a surface mount 478-pin CPU
socket. This socket is exclusively designed for installing an Intel
processor.
2.3.2 Installing the CPU
1. Locate Socket 478 on the system board.
2. Unlock the socket by pushing the lever sideways, away from the
socket, then lifting it up to a 90oangle. Make sure the socket is
lifted to at least this angle otherwise the CPU will not fit in
properly.

3. Position the CPU above the socket then align the gold mark
on the corner of the CPU (designated as pin 1) with pin 1 of
the socket.
Important:
Handle the CPU by its edges and avoid touching the pins.
Gold mark
4. Insert the CPU into the socket until it is seated in place. The
CPU will fit in only one orientation and can easily be inserted
without exerting any force.
Important:
Do not force the CPU into the socket. Forcing the CPU into
the socket may bend the pins and damage the CPU.
