Introduction

Expansion Slots

The system board is equipped with 1 dedicated AGP slot and 5

dedicated PCI slots. All PCI slots are bus masters. AGP is an

interface designed to support high performance 3D graphics cards.

It utilizes a dedicated pipeline to access system memory for

texturing, z-buffering and alpha blending; delivering up to 533MB/

sec. bandwidth for 3D graphics applications.

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.

and fan speed

Introduction

1.1.3 Intelligence

Automatic CPU/Chassis Fan Off

The CPU and chassis fans will automatically turn off once the

system enters the Suspend mode.

Dual Function Power Button

Depending on the setting in the BIOS 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 for more information.

Wake-On-LAN Ready

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.

Important:

The 5VSB power source of your power supply must support

≥

720mA (minimum).

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

Configuration 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.

Introduction

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.
