Special Features of the System Board
Watchdog Timer
The Watchdog Timer function allows your application to regularly
“clear” the system at the set time interval. If the system hangs or
fails to function, it will reset at the set time interval so that your
system will continue to operate.
Hyper-Threading Technology Functionality Requirements
The system board supports Intel processors with Hyper-Threading
Technology. 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 a bout enabling the
functionality of the Hyper-Threading Technology. For more information
on Hyper-Threading Technology, go to: www.intel.com/info/
hyperthreading.
DDR
DDR (Double Data Rate) is a type of SDRAM that doubles 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.
Dual Function Power Button
Depending on the setting in the “Soft-Off By PWR-BTTN” field of
the Power Management Setup, this switch will allow the system to
enter the Soft-Off or Suspend mode.

Introduction

AGP (Accelerated Graphics Port)
The AGP slot only supports 1.5V AGP 4x (1066MB/sec. bandwidth)
add-in cards. AGP is an interface designed to support high
performance 3D graphics cards for 3D graphics applications. It
handles large amounts of graphics data with the following features:
• Pipelined memory read and write operations that hide memory
access latency.
• Demultiplexing of address and data on the bus for nearly 100
percent efficiency.
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.
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 ports. USB 1.1
supports 12Mb/second bandwidth while USB 2.0 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.

Introduction

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, internal 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 a minimum of ≥ 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 5VSB power source of your power supply must support
≥ 720mA.
Wake-On-PS/2 Keyboard/Mouse
This function allows you to use the PS/2 keyboard or PS/2 mouse
to power-on the system.
Important:
The 5VSB power source of your power supply must support
≥ 720mA.

Introduction

14
Wake-On-USB Keyboard
This function allows you to use a USB keyboard to wake up a
system from the S3 (STR - Suspend To RAM) state.
Important:
If you are using the Wake-On-USB Keyboard function for 2 USB
ports, the 5VSB power source of your power supply must
support ≥ 1.5A. For 3 or more USB ports, the 5VSB 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
automatically power-on on the set date and time.
ACPI
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®®
®®
®98SE/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®®
®®
®98SE/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.

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.
Package Checklist
The system board package contains the following items:
;The system board
;A user’s manual
;One IDE cable
;One floppy disk drive cable
;One “Main Board Utility” CD

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 supports DDR SDRAM DIMM. Double Data
Rate SDRAM (DDR SDRAM) is a type of SDRAM that doubles 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 doubling the speed of data transfer.

Hardware Installation
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.

CPU
Overview
The system board is equipped with a surface mount 478-pin CPU
socket. This socket is exclusively designed for installing an Intel
processor.
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.
