Please refer to “System Memory” in chapter 2 for more information.

Chapter1-Introduction

Introduction

Expansion Slots

The system board is equipped with 1 AGP slot, 4

dedicated PCI slots and 1 shared PCI/CNR slot.

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.

CNR (Communication and Networking Riser) is an

interface that supports multi-channel audio, V.90

analog modem, phone-line based networking or 10/100

Ethernet based networking riser board.

Onboard Audio Features

• 18-bit stereo full-duplex codec with independent

variable sampling rate

• High quality differential CD input

• True stereo line level outputs

Compatibility

• Microsoft PC 2001 compliant

• PCI 2.2, CNR 1.0 “A” type and AC ’97 compliant

• Intel AGP version 2.0

IrDA Interface

The system board is equipped with an IrDA connector

for wireless connectivity between your computer and

peripheral devices. It supports peripheral devices that

meet the IrDA or ASKIR standard.

Introduction

USB Ports

The system board supports 4 USB ports. Two onboard

USB ports are located at the ATX double deck ports of

the board. The J16/J50 connector on the system board

allows you to connect 2 more optional USB ports. These

optional USB ports, which are mounted on a card-edge

bracket, will be provided as an option. USB allows data

exchange between your computer and a wide range of

simultaneously accessible external Plug and Play

peripherals.

• Flash EPROM for easy BIOS upgrades

• Supports DMI 2.0 function

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 System Health Monitor Functions

The system board is capable of monitoring the

following “system health” conditions.

• Monitors system temperature and overheat alarm

• Monitors 5VSB/VBAT/1.5V/3.3V/5V/±12V/CPU volt-

ages and failure alarm

• Monitors the fan speed of the CPU fan, chassis fan

and second fan; and failure alarm

Introduction

• Automatic chassis fan on/off control

• Read back capability that displays temperature,

voltage and fan speed

• Opened chassis alarm (optional)

Refer to the “PC Health Status” section in chapter 3 for

more information.

1.1.3 Intelligence

Automatic Chassis Fan Off

The chassis fan will automatically turn off once the

system enters the Suspend mode.

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 through an internal or external

modem. Refer to “Wake-On-Ring Connector” in chapter

2 and “Resume On Ring” in the Power Management

Setup section in chapter 3 for more information.

Important:

If you are using a modem add-in card, the 5VSB

power source of your power supply must support

≥720mA.

Introduction

Wake-On-LAN

The Wake-On-LAN function allows the network to

remotely wake up a Soft Power Down (Soft-Off) PC.

Your LAN card must support the remote wakeup

function. Refer to “Wake-On-LAN Connector” in chapter

2 and “Resume On LAN” in the Power Management

Setup section in chapter 3 for more information.

Important:

The 5VSB power source of your power supply

must support ≥720mA.

Wake-On-Keyboard/Wake-On-Mouse

This function allows you to use the keyboard or PS/2

mouse to power-on the system. Refer to “Jumper

Settings for Wake-On-Keyboard/Wake-On-Mouse” in

chapter 2 and “Keyboard/Mouse Power On” in the

Integrated Peripherals section in chapter 3 for more

information.

Important:

• The power button will not function once a

keyboard password has been set in the “KB

Power On Password” field of the Integrated

Peripherals submenu. You must type the

correct password to power-on the system. If

you forgot the password, power-off the system

and remove the battery. Wait for a few seconds

and install it back before powering-on the

system.

• The 5VSB power source of your power supply

must support ≥720mA.
