Desktop Management Interface (DMI)
The mainboard 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 this information in the DMI
pool, which is a part of the mainboard'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

1.1.3 Intelligence
utomatic 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 PWRBTN” 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 LAN/Ring” (“IRQ/Event
Activity Detect” field) 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-L N
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/Ring” (“IRQ/Event Activity Detect”
field) 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-PS/2 Keyboard
This function allows you to use the PS/ keyboard to wake up the
system from the S5 state. Refer to “Jumper Settings for Wake-On-
PS/ Keyboard” in chapter and “PS KB Wakeup Select” (“IRQ/
Event Activity Detect” field) in the Power Management section in
chapter 3 for more information.
Important:
• If you forgot the password, you must power-off the system,
unplug the power cord and clear the CMOS data Follow
the steps in the “Jumper Settings for Clearing CMOS Data”
section in chapter 2
• 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 “Jumper Settings for Wake-On-USB Keyboard”
in chapter and “USB Resume from S3” (“IRQ/Event Activity
Detect” field) 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
RTC Timer to Power-on the System
The RTC installed on the mainboard allows your system to auto-
matically power-on on the set date and time. Refer to “Resume On-
Alarm” (“IRQ/Event Activity Detect” field) in the Power Management
Setup section in chapter 3 for more information.

Introduction
13
CPI STR
The mainboard is designed to meet the ACPI (Advanced Configura-
tion and Power Interface) specification. ACPI has energy saving fea-
tures 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
C Power Failure 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 Power
Management Setup section in chapter 3 for more information.
Virus Protection
Most viruses today destroy data stored in hard drives. The
mainboard 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 mainboard, processor,
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 mainboard is equipped with three 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.
Refer to chapter 1 (System Memory section for detailed
specification of the memory supported by the mainboard.

Hardware Installation
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.
2.2.1 Installing the DIM Module
A DIM module simply snaps into a DIMM socket on the mainboard.
Pin 1 of the DIM module must correspond with pin 1 of the socket.

2.3 Jumper Settings for Clearing CMOS Data
Clear CMOS Data - J mper JP4
If you encounter the following,
a) CMOS data becomes corrupted.
b) You forgot the keyboard, supervisor or user password.
c) You are unable to boot-up the computer system because the
processor’s ratio/clock was 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 and unplug the power cord.
2. Set JP4 pins 2 and 3 to On. Wait for a few seconds and set JP4
back to its default setting, pins 1 and 2 On.

setting of the processor’s ratio/clock in the BIOS, please proceed
to step 4.
4. After powering-on the system, press <Del> to enter the main
menu of the BIOS.
5. Select the Frequency/Voltage Control submenu and press
<Enter>.
6. Set the “CPU Clock Ratio” or “CPU Clock” field to its default
setting or an appropriate frequency ratio or bus clock. Refer to
the Frequency/Voltage Control section in chapter 3 for more
information.
7. Press <Esc> to return to the main menu of the BIOS setup
utility. Select “Save & Exit Setup” and press <Enter>.
8. Type <Y> and press <Enter>.
