Introduction
Static Electricity Precautions
It is quite easy to inadvertently damage your PC, system board,
components or devices even before installing them in your system
unit. Static electrical discharge can damage computer components
without causing any signs of physical damage. You must take extra
care in handling them to ensure against electrostatic build-up.
1. To prevent electrostatic build-up, leave the system board in its
anti-static bag until you are ready to install it.
2. Wear an antistatic wrist strap.
3. Do all preparation work on a static-free surface.
4. Hold the device only by its edges. Be careful not to touch any of
the components, contacts or connections.
5. Avoid touching the pins or contacts on all modules and connec-
tors. Hold modules or connectors by their ends.
Important:
Electrostatic discharge (ESD) can damage your processor,
disk drive and other components. Perform the upgrade in-
struction 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 requir-
ing ESD protection.
Safety Measures
To avoid damage to the system:
• Use the correct AC input voltage range.....
To reduce the risk of electric shock:
• Unplug the power cord before removing the system chassis
cover for installation or servicing. After installation or servicing,
cover the system chassis before plugging the power cord.

Introduction
Features
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.
DDR2 is a higher performance DDR technology
whose data transfer rate delivers bandwidth of 4.3
GB per second and beyond. That is twice the speed of the conven-
tional DDR without increasing its power consumption. DDR2
SDRAM modules work at 1.8V supply compared to 2.6V memory
voltage for DDR modules. DDR2 also incorporates new innovations
such as the On-Die Termination (ODT) as well as larger 4-bit pre-
fetch against DDR which fetches 2 bits per clock cycle.
The Intel northbridge chip comes integrated with the
Intel Graphics Media Accelerator X3100 delivering
exceptional 3D graphics performance. It supports analog CRT and
DVI interfaces.
DVI (Digital Visual Interface) is a form of video inter-
face technology made to maximize the quality of flat
panel LCD monitors and modern video graphics cards. Data is
transmitted using the TMDS (Transition Minimized Differential
Signaling) protocol, providing a digital signal from the PC’s graphics
subsystem to the display.
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 usually 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 out-
puts to amplifiers and speakers and to digital recording devices like
CD recorders.

Introduction
Serial ATA is a storage interface that is compliant
with SATA 1.0a specification. With speed of up to
3Gbps, it improves hard drive performance faster than the standard
parallel ATA whose data transfer rate is 100MB/s.
The Realtek RTL8111C PCI Express Gigabit
controller supports up to 1Gbps data transmis-
sion.
The system board supports USB 2.0 and USB 1.1
ports. USB 1.1 supports 12Mb/second bandwidth
while USB 2.0 supports 480Mb/second bandwidth providing a
marked improvement in device transfer speeds between your com-
puter and a wide range of simultaneously accessible external Plug
and Play peripherals.
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 mo-
dem or respond to calls from a PCI modem card that uses the PCI
PME (Power Management Event) signal to remotely wake up the
PC.
Important:
The 5V_standby power source of your power supply must sup-
port ≥ 720mA.
This feature allows the network to remotely
wake up a Soft Power Down (Soft-Off) PC.
It is supported via the onboard LAN port or via a PCI LAN card
that uses the PCI PME (Power Management Event) signal. However,
if your system is in the Suspend mode, you can power-on the system
only through an IRQ or DMA interrupt.
Important:
The 5V_standby power source of your power supply must sup-
port ≥ 720mA.

Introduction
This function allows you to use the PS/2 key-
board or PS/2 mouse to power-on the sys-
tem.
Important:
The 5V_standby power source of your power supply must sup-
port ≥ 720mA.
This function allows you to use a USB key-
board 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 function for
2 USB ports, the 5V_standby power source of your power sup-
ply must support ≥ 1.5A. For 3 or more USB ports, the
5V_standby power source of your power supply must support
≥ 2A.
The RTC installed on the system board allows your
system to automatically power-on on the set date
and time.
The system board is designed to meet the ACPI
(Advanced Configuration and Power Interface) specifi-
cation. ACPI has energy saving features that enables PCs to imple-
ment Power Management and Plug-and-Play with operating systems
that support OS Direct Power Management. 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 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.
