ChoosingaComputerCase
There are many types of computer cases on the market. The motherboard complies with
the specifications for the Micro ATX system case. First, some features on the motherboard
are implemented by cabling connectors on the motherboard to indicators and switches on
the system case. Make sure that your case supports all the features required. Secondly, it
supports one floppy diskette drive and one enhanced IDE drive. Make sure that your case
has sufficient power and space for all 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 carries a Micro ATX form factor of 244 x 200 mm. Choose a case that
accommodates this form factor.
InstallingtheMotherboard in aCase
Refer to the following illustration and instructions for installing the motherboard in a case.
Most system cases have mounting brackets installed in the case, which correspond the holes
in the motherboard. Place the motherboard over the mounting brackets and secure the
motherboard onto the mounting brackets with screws.

CheckingJumperSettings
This section explains how to set jumpers for correct configuration of the motherboard.
SettingJumpers
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 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
SHORT OPEN
Do not over-tighten the screws as this can stress the motherboard.

Connecting 20/24-pin power cable
Users please note that the 20-pin and 24-pin power cables can both be connected
to the ATX1 connector. With the 20-pin power cable, just align the 20-pin power
cable with the pin 1 of the ATX1 connector. However, using 20-pin power cable
may cause the system to become unbootable or unstable because of insufficient
electricity. A minimum power of 300W is recommended for a fully-configured
system
20-pin power cable
24-pin power cable
Users please note that when installing 20-
pin power cable, the latche of power cable
falls on the left side of the PWR1 connector
latch, just as the picture shows.

Front Panel Header
The front panel header (PANEL1) provides a standard set of switch and LED headers
commonly found on ATX or Micro ATX cases. Refer to the table below for information:
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 pin 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 de-
bounce 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 over-clock processors or other components to run
faster than their rated speed.
Warning: Over-clocking components can adversely affect the reliability of
the system and introduce errors into your system. Over-clocking can
permanently damage the motherboard by generating excess heat in
components that are run beyond the rated limits.
This motherboard has a LGA775 socket. When choosing a processor, consider the perfor-
mance 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.
