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 4-channel audio connector which supports four audio output
signals: center channel, subwoofer, rear right channel and rear left
channel; together with the line-in and mic-in jacks (at the rear panel)
support 6-channel audio output.

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 .0 and USB 1.1. USB 1.1
supports 1 Mb/second bandwidth while USB .0 supports 480Mb/
second bandwidth providing a marked improvement in device
transfer speeds between your computer and a wide range of
simultaneously accessible external Plug and Play peripherals.
BIOS
• Award BIOS, Windows® 98/ 000/ME/XP Plug and Play
compatible
• Supports SCSI sequential boot-up
• Flash EPROM for easy BIOS upgrades
• Supports DMI .0 function
• Mbit flash memory
Desktop Management Interface (DMI
The system board comes with a DMI .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.
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 5 SB 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, via
a PCI LAN card that uses the PCI PME (Power Management Event)
signal or via a LAN card that uses the Wake-On-LAN connector.
However, if your system is in the Suspend mode, you can power-on
the system only through an IRQ or DMA interrupt.
Important:
The 5 SB power source of your power supply must support
≥ 720mA.

Introduction

Wake-On-PS/2 Keyboard
This function allows you to use the PS/ keyboard to wake up the
system from the S5 state.
Important:
The 5 SB power source of your power supply must support
≥ 720mA.
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 5 SB power source of your
power supply must support ≥ 1.5A.
• If you are using the Wake-On-USB Keyboard/Mouse
function for 3 or more USB ports, the 5 SB power source
of your power supply must support ≥ 2A.
RTC Timer 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/ 000/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/ 000/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

1
Introduction
13
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 5 SB power source of your power supply must support
≥ 1A.
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
Please 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/

2.2 System Memory
Warning:
Electrostatic discharge (ESD) can damage your system board,
processor, 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 three 184-pin DDR DIMM
sockets. DDR (Doub e Data Rate) is a type of SDRAM that
doub es the data rate through reading and writing at both the rising
and fa ing edge of each c ock. This effective y doub es the speed of
operation therefore providing two times faster data transfer.
Refer to chapter 1 (System Memory section) for detai ed
specification of the memory supported by the system board.
