The mainboard uses Double Data Rate Dual Inline Memory Modules (DDR

DIMM). Each mainboard has two 184-pin DIMM sockets which support 2.5V

(power level) single-sided or double-sided PC1600 (DDR200) or PC2100

(DDR266) DDR DIMM modules.

Expansion Slots

The mainboard is equipped with three dedicated PCI slots and one 1.5V

2X/4X AGP slot.

Onboard Audio Feature

The mainboard supports Microsoft DirectSound/DirectSound 3D and AC97 2

channels. The AC’97 Codec is ALC202A.

WOL (Wake-On-LAN) Connector

The mainboard supports Wake-On-LAN functionality.

Front Side Bus Frequency (FSB)

The Front Side Bus Frequency (FSB) clock is 200/266 MHz.

BIOS

!Award BIOS, Windows 95/98 Plug and Play (PnP) compatible

!Supports SCSI sequential boot-up

!2 Mb flash ROM for easy BIOS upgrades

!Supports DMI2.0 function

Desktop Management Interface (DMI)

The mainboard comes with DMI2.0 built into the BIOS. The DMI utility in the

BIOS will automatically record different information about your system

configuration and store this 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 for easy inventory, maintenance and the

simplified troubleshooting of computer systems.

Introduction

USB2.0 Ports

USB allows data exchange between your computer and a wide range of

simultaneously accessible external Plug and Play peripherals. The mainboard is

equipped with six USB (version 2.0) connectors. USB1 and USB2 are external

connectors. They can be found on the PC 99 ATX connector. The other USB

connectors are internal connectors and can be used to connect other USB

devices. (Cables for the internal connectors are sold separately).

Introduction

Hardware Monitoring System Utility

The mainboard comes with the Hardware Monitoring System utility contained

on the CD. It is capable of monitoring the system’s hardware conditions such

as the temperature of the processor, voltage, and the speed of both the CPU

and chassis fans. You are allowed to manually set a range to the items being

monitored. If the values are over or under the set range a warning message

will automatically pop up. We recommend that you use the Default Settings,

which are the ideal settings that will maintain the system in a good working

condition. To install this utility, please insert the CD into the CD-ROM drive.

The auto run screen (Driver Utility) will automatically appear. Click the Hard-

ware Monitoring button, choose the chipset, model number and the OS that is

installed. Please refer to the CD “Readme” file for further installation instruc-

tions.

Note: Only use this utility in Windows operating systems.

The mainboard is capable of monitoring the following health conditions of your

system:

1. Processor temperature. It has an overheat alarm.

2. VCORE/3.3V/5V/12V/-12V voltages and failure alarm.

3. Processor and chassis fan speeds. It has a failure alarm for these fans.

4. Read back capability that displays temperature, voltage and fan speed.

Dual Function Power Button

Depending on the setting in the Soft-Off By Power-Button field of the Power

Management Setup, this switch allows the system to enter the Soft-Off or

Suspend mode.

RTC Timer to Power-on the System

The RTC installed on the system board allows your system to automatically

power-on at a set date and time.

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. The 5V SB power source of your power supply must be at least

720mA.

ACPI Ready

The mainboard is designed to meet the ACPI (Advanced Configuration and

Power Interface) specification. ACPI has energy saving features that support

OS Direct Power Management (OSPM) for round the clock PC operation.
