There are many types of computer cases on the market. The mainboard com-
plies with the specifications for the Full-ATX system case. Some features on
the mainboard are implemented by cabling connectors on the mainboard to
indicators and switches on the system case. Ensure that your case supports
all the features required. The mainboard can support one or two floppy disk-
ette drives and four enhanced IDE drives. Ensure that your case has sufficient
power and space for all the drives that you intend to install.
Most cases have a choice of I/O templates in the rear panel. Make sure that
the I/O template in the case matches the I/O ports installed on the rear edge
of the mainboard.
This mainboard has a Full-ATX form factor of304.8 mm x 244 mm. Choose a
case that accommodates this form factor.

Follow these safety precautions when installing the mainboard:
•Wear a grounding strap attached to a grounded device to avoid
damage from static electricity.
•Discharge static electricity by touching the metal case of a safely
grounded object before working on the mainboard.
•Leave components in the static-proof bags they came in.
•Hold all circuit boards by the edges. Do not bend circuit boards.

ample of a mainboard being
installed in a tower-type case:
Note: Do not overtighten
the screws as this
can stress the main-
board.
Most system cases have
mounting brackets installed in
the case, which correspond to
the holes in the mainboard.
Place the mainboard over the
mounting brackets and secure
the mainboard onto the mount-
ing brackets with screws.
2. Secure the mainboard with

This section explains how to set jumpers for correct configuration of the main-
board.
Setting Jumpers
Use the mainboard jumpers to set system configuration options. Jumpers with
more than one pin are numbered. When setting the jumpers, ensure that the
jumper caps are placed on the correct pins.
The illustrations below show a 2-pin jumper.
When the jumper cap is placed on both pins,
the jumper is SHORT. If you remove the
jumper cap, or place the jumper cap on just
one pin, the jumper is OPEN.
This illustration shows a 3-pin
jumper. Pins 1 and 2 are SHORT.

3. Short pins 2 and 3 on JP1.
4. Return the jumper to the normal setting.
Plug in all ATX power connectors.
JP3 –Enables you to prevent the BIOS from being updated
(flashed). Open the jumper if you are going to update your
BIOS. After updating the BIOS, short the jumper to protect
the BIOS from being flashed.

Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the mainboard or any of thesurface-mount resistors
with the clip of the cooling fan. If the clip of the cooling fan scrapes
across the mainboard, you may cause serious damage to the mainboard
or its components.
On most mainboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-lit work area so that you can
clearly see the mainboard and processor socket.
Before installing the Processor
This mainboard automatically determines the CPU clock frequency and sys-
tem bus frequency for the processor. You may be able to change these
settings by making changes to jumpers on the mainboard, or changing the
settings in the system Setup Utility. We strongly recommend that you do not
overclock processors or other components to run faster than their rated speed.
Warning: Overclocking components can adversely affect the reliability of
the system and introduce errors into your system. Overclocking can per-
manently damage the mainboard by generating excess heat in
components that are run beyond the rated limits.
This mainboard has a mPGA478 socket. When choosing a processor, con-
sider the performance requirements of the system. Performance is based on
the processor design, the clock speed and system bus frequency of the proc-
essor, and the quantity of internal cache memory and external cache memory.

CPU Installation Procedure
The following illustration shows CPU installation components:
Note: The pin-1 corner is marked with an arrow
Follow these instructions to install the CPU:
1. Install and secure the Retention Module on the mainboard.
2. Pull the CPU socket-locking lever away fromthe socket to unhook it and raise
the locking lever to the upright position.
3. Match the corner on the
CPU marked with an arrow
with pin-1 on the CPU
socket (the corner with the
pinhole noticeably missing).
Insert the processor into the
socket. Do not use force.
4. Swing the locking lever down and hook it under the latch on the edge of the
socket.
5. Apply thermal grease to the top of the CPU.
6. Lower the heatsink over the CPU.

7. Lower the CPU cooling fan onto
the heatsink.
8. Snap the four retention legs of
the cooling fan into place.
Cooling Fan
Retention Module
Heatsink
9. Swing both lock levers on top of the cooling fan to their opposite sides to
secure the cooling fan on top of the heatsink.
10. Connect the CPU Cooling Fan
power cable to the CPUFAN1
connector.
Note:CPU fan and heatsink installation procedures may vary with the type of
CPU fan/heatsink supplied. The form and size of fan/heatsink may also
vary.
