compatible
• Supports SCSI sequential boot-up
• Flash EPROM for easy BIOS upgrades
• Supports DMI .0 function
Desktop Management Interface (DMI)
The system board comes with a DMI .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/3.3V/5V/±1 V/CPU voltages and failure
alarm
• Monitors the fan speed of the CPU fan, chassis fan and system
fan; and failure alarm
• 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 and the
“Hardware Doctor” section in chapter 4 for more information.

1.1.3 Intelligence
A tomatic Chassis Fan Off
The chassis fan will automatically turn off once the system enters the
Suspend mode.
D al F nction Power B tton
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 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
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 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

Introduction
Wake-On-Keyboard/Wake-On-Mo se
This function allows you to use the keyboard or PS/ mouse to
power-on the system. Refer to “Jumper Settings for Wake-On-
Keyboard/Wake-On-Mouse” in chapter 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
Wake-On-USB Keyboard
The Wake-On-USB Keyboard function allows you to use a USB
keyboard to wake up a system that is in the S3 (STR - Suspend To
RAM) state. Refer to “USB KB Wake-Up From S3” in the Power
Management Setup section in chapter 3 for more information.
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
• If you are using the Wake-On-USB Keyboard function 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. Refer to “Resume
By Alarm” in the Power Management Setup section in chapter 3 for
more information.

ACPI STR
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. Currently, only Windows® 98/ 000/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/ 000/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. Refer to “Using the
Suspend to RAM Function” in appendix A for more information.
Important:
The 5VSB power source of your power supply must support
≥ 1A
AC Power Fail re 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. Refer to “PWR Lost Resume State” in the Integrated
Peripherals section in chapter 3 for more information.
Vir s 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.

2.2 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 orkstation
only. If such a station is not available, you can provide some ESD
protection by earing an antistatic rist strap and attaching it to a
metal part of the system chassis. If a rist strap is unavailable,
establish and maintain contact ith the system chassis throughout
any procedures requiring ESD protection.
The mainboard is equipped with two 184-pin DDR SDRAM DIMM
(Dual In-line Memory Module sockets that suppor t 2.5V 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.
The system board also supports the ECC (Error Checking and
Correction function. To use this function, you must install DIMM that
supports parity. Refer to chapter 1 (System Memory section for
detailed specification of the memory supported by the system
board. “Memor y Frequency For” in the Advanced Chipset Features
submenu of the BIOS must be set accordingly.

2Hardware Installation
2.2.1 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.

2.3 Jumper Settings for Clearing CMOS Data
Clear CMOS Data - Jumper JP3
If you encounter the following,
a) CMOS data becomes corrupted.
b) You forgot the supervisor or user pass ord.
c) You are unable to boot-up the computer system because the
processor’s ratio/clock as incorrectly set in the BIOS.
you can reconfigure the system with the default values stored in the
ROM BIOS.
To load the default values stored in the ROM BIOS, please follow
the steps below.
1. Power-off the system.
