1.1.3 Intelligence
Automatic System Fan 1 Off
The system fan 1 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 2 and “Resume On Ring” (“PM Wake Up
Events” 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-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 Ring” (“PM Wake Up Events” 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.
Introduction

Wake-On-PS/2 Keyboard/Mouse
This function allows you to use the PS/2 keyboard or PS/2 mouse
to wake up a system from the S3/S4/S5 state. Refer to “PS2KB
Function As” and “PS2 Mouse Wake Up” (“PM Wake Up Events”
field) in the Power Management Setup 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
The Wake-On-USB function allows you to use a USB device to
wake up a system from the S3/S4/S5 state. Refer to “USB Device
Wake Up” (“PM Wake Up Events” field) in the Power Management
Setup section in chapter 3 for more information.
Important:
• If you are using the Wake-On-USB 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 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 and
“Resume By Alarm” (“PM Wake Up Events” field) 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® 98/2000/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® 98/2000/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 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 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 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 system board 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 for the type of memory supported by the
system board.

Installing the DDR SDRAM DIMM
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 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 JP3 pins 1 and 2 to On. Wait for a few seconds and set JP3
back to its default setting, pins 2 and 3 On.

2.5.4 Floppy Disk Drive Connector
The system board is equipped with a shrouded floppy disk drive
connector that supports two standard floppy disk drives. To prevent
improper floppy cable installation, the shrouded floppy disk header
has a keying mechanism. The 34-pin connector on the floppy cable
can be placed into the header only if pin 1 of the connector is
aligned with pin 1 of the header. You may enable or disable this
function in the Integrated Peripherals submenu (“Onboard Super IO
Device” field) of the BIOS.
Connecting the Floppy Disk Drive Cable
1. Install the 34-pin header connector of the floppy disk drive cable
into the shrouded floppy disk header (Floppy) on the system
board. The colored edge of the ribbon should be aligned with pin
1 of Floppy.
2. Install the other 34-pin header connector(s) into the disk drive(s).
Align the colored edge of the daisy chained ribbon cable with pin
1 of the drive edge connector(s). The end-most connector should
be attached to the drive you want to designate as Drive A.

1. If you are connecting two IDE drives, install the 40-pin connector
of the IDE cable into the primary shrouded IDE header
(connector IDE 1). If you are adding a third or fourth IDE device,
install the 40-pin connector of the other IDE cable into the
secondary shrouded IDE header (connector IDE 2).
2. Install the other 40-pin header connector(s) into the device with
the colored edge of the ribbon cable aligned with pin 1 of the
drive edge connector(s).
Note:
Refer to your disk drive user’s manual for information about
selecting proper drive switch settings.

Adding a Second IDE Disk Drive
When using two IDE drives, one must be set as the master and the
other as the slave. Follow the instructions provided by the drive
manufacturer for setting the jumpers and/or switches on the drives.
The system board supports Enhanced IDE or ATA-2, ATA/33,
ATA/66, ATA/100 or ATA/133 hard drives. We recommend that you
use hard drives from the same manufacturer. In a few cases, drives
from two different manufacturers will not function properly when
used together. The problem lies in the hard drives, not the system
board.
Important:
If you encountered problems while using an ATAPI CD-ROM
drive that is set in Master mode, please set the CD-ROM drive
to Slave mode. Some ATAPI CD-ROMs may not be recognized
and cannot be used if incorrectly set in Master mode.
