There are many types of computer cases on the market. The motherboard
complies with the specifications for the Micro-ATX system case. Some features on the motherboard are implemented by cabling connectors on the
motherboard to indicators and switches on the system case. Ensure that your
case supports all the features required. The motherboard can support one or
two floppy diskette 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 motherboard.
This motherboard has a Micro-ATX form factor of 244 mm x 200 mm. Choose
a case that accommodates this form factor.

Installing the Motherboard
SSaaffeettyy PPrreeccaauuttiioonnss
Follow these safety precautions when installing the motherboard:
• 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 motherboard.
• Leave components in the static-proof bags they came in.
• Hold all circuit boards by the edges. Do not bend circuit boards.

Refer to the following illustration and instructions for installing the motherboard in a case:
This illustration shows an example of a motherboard being
installed in a tower-type case:
Note: Do not overtighten
the screws as this
can stress the motherboard.
Most system cases have
mounting brackets installed in
the case, which correspond to
the holes in the motherboard.
Place the motherboard over
the mounting brackets and
secure the motherboard onto
the mounting brackets with
screws.
Ensure that your case has an I/O template that supports the I/O ports and
expansion slots on your motherboard.

This section explains how to set jumpers for correct configuration of the motherboard.
Setting Jumpers
Use the motherboard 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.
Short Open
This illustration shows a 3-pin
jumper. Pins 1 and 2 are SHORT.

Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indication that data is being read from or written to the hard drive. For the LED to
function properly, an IDE drive should be connected to the onboard IDE interface. The LED will also show activity for devices connected to the SCSI (hard
drive activity LED) connector.

Power / Sleep / Message Waiting LED
Connecting pins 2 and 4 to a single- or dual-color, front panel mounted LED
provides power on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pins 5 and 7 to a momentary-contact switch that is normally open. When the switch is closed, the board
resets and runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a
momentary-contact switch that is normally open. The switch should maintain
contact for at least 50 ms to signal the power supply to switch on or off. The
time requirement is due to internal debounce circuitry. After receiving a power
on/off signal, at least two seconds elapses before the power supply recognizes another on/off signal.

Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the motherboard or any of the surface-mount resistors with the clip of the cooling fan. If the clip of the cooling fan scrapes
across the motherboard, you may cause serious damage to the motherboard or its components.
On most motherboards, 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 motherboard and processor socket.
Before installing the Processor
This motherboard automatically determines the CPU clock frequency and
system bus frequency for the processor. You may be able to change these
settings by making changes to jumpers on the motherboard, 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 permanently damage the motherboard by generating excess heat in
components that are run beyond the rated limits.
This motherboard has an mPGA478 socket. When choosing a processor,
consider the performance requirements of the system. Performance is based
on the processor design, the clock speed and system bus frequency of the
processor, and the quantity of internal cache memory and external cache
memory.
