FCC and DOC Statement on Class B
This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the FCC
rules. 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 ra-
diate radio frequency energy and, if not installed and used in ac-
cordance with the instruction manual, may cause harmful interfer-
ence 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 re-
ceiver.
• 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 author-
ity to operate the equipment.
2. Shielded interface cables must be used in order to comply
with the emission limits.

S/PDIF
S/PDIF is a standard audio file transfer format that transfers digital
audio signals to a device without having to be converted first to
an analog format. This prevents the quality of the audio signal
from degrading whenever it is converted to analog. S/PDIF is usu-
ally found on digital audio equipment such as a DAT machine or
audio processing device. The S/PDIF connector on the system
board sends surround sound and 3D audio signal outputs to am-
plifiers and speakers and to digital recording devices like CD re-
corders.

Watchdog Timer
The Watchdog Timer function allows your application to regularly
“clear” the system at the set time interval. If the system hangs or
fails to function, it will reset at the set time interval so that your
system will continue to operate.

1.1.3 Intelligence
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-LAN
This feature allows the network to remotely wake up a Soft
Power Down (Soft-Off) PC. It is supported via the onboard LAN
port, via a PCI LAN card that uses the PCI PME (Power Manage-
ment Event) signal or via a LAN card that uses the Wake-On-
LAN connector. However, if your system is in the Suspend mode,
you can power-on the system only through an IRQ or DMA
interrupt.
Important:
The 5VSB power source of your power supply must support
≥ 720mA.
Wake-On-PS/2 Keyboard/Mouse
This function allows you to use the PS/2 keyboard or PS/2
mouse to power-on the system.
Important:
The 5VSB power source of your power supply must support
≥ 720mA.
Wake-On-USB
This function allows you to use a USB device to wake up a
system that is in the S3 (STR - Suspend To RAM) state.
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.
ACPI STR
The system board is designed to meet the ACPI (Advanced Con-
figuration and Power Interface) specification. ACPI has energy sav-
ing 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.
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 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.
Refer to chapter 1 (System Memory section) for detailed specifi-
cation of the memory supported by the system board.
BIOS Setting
Configure the system memory in the Advanced Chipset Features
submenu of the BIOS.

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.

2.3.1 Overview
The system board is equipped with a surface mount 478-pin CPU
socket. This socket is exclusively designed for installing an Intel
processor.
2.3.2 Installing the CPU
1. Locate Socket 478 on the system board.
2. Unlock the socket by pushing the lever sideways, away from the
socket, then lifting it up to a 90oangle. Make sure the socket is
lifted to at least this angle otherwise the CPU will not fit in properly.
