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-

1.1.2 Intelligence
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 from an external modem or respond to calls from a
modem PCI card that uses the PCI PME (Power Management
Event) signal to remotely wake up the PC.
Important:
If you are using a modem add-in card, the 5VSB power source
of your power supply must support a minimum of ≥ 720mA.

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 and via a PCI LAN card that uses the PCI PME (Power
Management Event) signal. However, if your system is in the Sus-
pend 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 Keyboard/Mouse
This function allows you to use a USB keyboard or USB mouse
to wake up a system from the S3 (STR - Suspend To RAM) state.
Important:
• If you are using the Wake-On-USB Keyboard/Mouse func-
tion 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/Mouse func-
tion 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®®
®®
®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 with-
out 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, proces-
sor, 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.

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 CPU
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.

3. Position the CPU above the socket then align the gold mark
on the corner of the CPU (designated as pin 1) with pin 1 of
the socket.
Important:
Handle the CPU by its edges and avoid touching the pins.

4. Insert the CPU into the socket until it is seated in place. The
CPU will fit in only one orientation and can easily be inserted
without exerting any force.
Important:
Do not force the CPU into the socket. Forcing the CPU into
the socket may bend the pins and damage the CPU.
