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 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.

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 connec­tors. Hold modules or connectors by their ends.
Important:
Electrostatic discharge (ESD) can damage your processor, disk drive 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.

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.
..
.
..
Battery:
Danger of explosion if battery incorrectly replaced.
Replace only with the same or equivalent type recommend the manufacturer.
Dispose of used batteries according to local ordinance.

Introduction
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 ing 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.

Channel A - SODIMM 1 Channel B - SODIMM 2
The system board supports the following memory interface.
Single Channel (SC)
Data will be accessed in chunks of 64 bits (8B) from the memory channels.
Dual Channel (DC)
Data will be accessed in chunks of 128 bits from the memory chan­nels. Dual channel provides better system performance because it doubles the data transfer rate.

Only one channel is populated with
SODIMM.
SODIMMs of different memory configura-
tions are on different channels.

Hardware Installation
Installing the DIM Module
Note:
The system board used in the following illustrations may not resemble the actual one. These illustrations are for reference only.
1. Make sure the PC and all other peripheral devices connected to it has been powered down.
2. Disconnect all power cords and cables.
3. Locate the SODIMM 2 socket on the system board.
4. Push the “ejector tabs” which are at the ends of the socket to the side.

5. Note how the module is keyed to the socket. Grasping the module by its edges, position the SODIMM above the socket with the “notch” in the module aligned with the “key” on the socket. The key ensures the module can be plugged into the socket in only one way.

6. Seat the module vertically, pressing it down firmly until it is com­pletely seated in the socket. The ejector tabs at each end of the socket will automatically snap into the locked position to hold the SODIMM in place.
7. To install another SODIMM, locate the SODIMM 1 socket on the system board.

8. Insert the module into the socket at an approximately 30 de­grees angle. Note that the socket and module are both keyed, which means the module can be plugged into the socket in only one way.
9. To seat the module into the socket, apply firm even pressure to each end of the module until it slips down into the socket. The contact fingers on the edge of the module will almost completely disappear inside the socket.

Overview
The system board is equipped with a surface mount mPGA478 CPU socket.
Installing the CPU
1. Make sure the PC and all other peripheral devices connected to it has been powered down.
2. Disconnect all power cords and cables.
3. Locate the mPGA478 socket on the system board.

5. Position the CPU above the socket. The gold triangular mark on the CPU must align with pin 1 of the CPU socket.
Important:
1. Only Use Intel® CoreTM Duo/Solo processor or Intel® Celeron® M processor manufactured on 65nm technology. Intel Pentium M and Intel Celeron
M processors manufactured on 0.13 micron and 90nm technology are not supported. Installing an incompatible processor will cause severe damage to both the proces­sor and system board.
2. Handle the CPU by its edges and avoid touching the pins.

6. 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. Use a screwdriver to turn the screw to its lock position.
Important:
Do not force the CPU into the socket. Forcing the CPU into the socket may bend the pins and damage the CPU.
22
Installing the Fan and Heat Sink
The CPU must be kept cool by using a CPU fan with heat sink. Without sufficient air circulation across the CPU and heat sink, the CPU will overheat damaging both the CPU and system board.
Note:
Use only certified fan and heat sink.
Your fan and heat sink package usually contains the fan
and heat sink assembly, and an installation guide. If the in­stallation procedure in the installation guide differs from the one in this section, please follow the installation guide in the package.
1. Match and insert the screw holes of the retention module base to the mounting holes around the CPU socket from the bottom through the top of the system board.

2. Place the heat sink on top of the CPU. The 4 screws around the heat sink must match the screw holes of the retention module base. Refer to the figure below for the correct position of the heat sink. This is important so that the fan / heat sink will pro­vide adequate cooling to the components of the system board.
Turn each Phillips head screw half way down first to initially stabi­lize the heat sink onto the system board, then finally tighten each screw.
Important:
Do not turn the first screw all the way down followed by the next and so on. This is to avoid imbalance which might cause cracks or fractures to the CPU and/or heat sink as­sembly.
24
Hardware Installation
Important:
When you install the CPU fan and heat sink assembly, make sure the assembly is positioned in such a way that the direc­tion of the airflow blows towards the Northbridge. This is to ensure optimum thermal condition and system performance.
