These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a residential
installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio
communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the
following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
• Consult the dealer or an experienced radio TV technician for
help.
Notice:
1. The changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority
to operate the equipment.
2. Shielded interface cables must be used in order to comply with
the emission limits.

1.1.3 Intelligence
Automatic System Fan Off
The system 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 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 2 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 is applicable only when you are using a
LAN add-in card that has the same function. It 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 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-Mouse
This function allows you to use the keyboard or PS/2 mouse to
power-on the system. Refer to “Jumper Settings for Wake-On-
Keyboard/Wake-On-Mouse” in chapter 2 and “Keyboard/Mouse
Power On” (“Onboard Super IO Device” field) 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 from the S3 (STR - Suspend To
RAM) state. Refer to “Jumper Settings for Wake-On-USB Keyboard”
in chapter 2 and “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.

Introduction

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®®
®®
®98SE/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®®
®®
®98SE/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.
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” (“Onboard Super
IO Device”) in the Integrated Peripherals 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.

1.2 Hyper-Threading Technology Functionality
Requirements
Enabling the functionality of Hyper-Threading Technology for your
computer system requires ALL of the following platforms.
Components:
• CPU - an Intel®Pentium®4 Processor with HT Technology
• Chipset - an Intel®chipset that supports HT Technology
• BIOS - a BIOS that supports HT Technology and has it enabled
• OS - an operating system that includes optimizations for HT
Technology
Please refer to Appendix A for information about enabling the
functionality of the Hyper-Threading Technology. For more information

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 supports 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 four DDR DIMM sockets on the system board are divided into 2
channels:
Channel A - sockets A1 and A2
Channel B - sockets B1 and B2

Hardware Installation
The system board supports single and/or dual channel DDR memory
interface. Inserting DIMMs on the same channel (e.g. A1 and A2 or
B1 and B2) provides single channel memory interface while DIMMs
inserted on different channels (e.g. A1 and B1 or A2 and B2) will
provide dual channel memory interface. Refer to the following tables

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.
