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.
DDR
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.
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.

Introduction

12
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.
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.
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.

Introduction
13
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.
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 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.

Introduction

Important:
The 5VSB power source of your power supply must support
≥ 1A.
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.

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 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.

Configure the system memory in the Advanced Chipset Features
submenu of the BIOS.

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 mPGA479M
(Socket 479) CPU socket. This socket is exclusively designed for
installing an Intel®Pentium®M / Celeron®M processor.
Installing the CPU
1. Make sure the PC and all other peripheral devices connected to
it has been powered down.
2. Disconnect all power cords and cables.
3. Locate the 479-pin CPU socket on the system board.

5. Position the CPU above the socket. The gold triangular mark on
the CPU must align with pin 1 of the CPU socket.
Important:
Handle the CPU by its edges and avoid touching the pins.
6. 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. Use a screwdriver to turn the screw
to its lock position.
Important:
Do not force the CPU into the socket. Forcing the CPU into
the socket may bend the pins and damage the CPU.

Installing the Fan and Heat Sink
The CPU must be kept cool by using a CPU fan with heat sink.
Without sufficient air circulation across the CPU and heat sink, the
CPU will overheat damaging both the CPU and system board.
Note:
•Use only the fan and heat sink assembly included in the
system board package.
•The fan and heat sink package contains the fan and heat
sink assembly, and a retension module base.
