Installing the Motherboard
Safety Precautions
• 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
Choosing a Computer Case
There are many types of computer cases on the market. The motherboard complies
with the specifications for the ATX system case. Firstly, 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, this motherboard supports two enhanced IDE drives.
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 an ATX form factor of 305 X 210 mm. Choose a case that
accommodates this form factor.
7
Installing the Motherboard in a Case
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.
Ensure that your case has an I/O template that supports the I/O ports and expansion
slots on your motherboard.
Installing the Motherboard

Do not over-tighten the screws as this can stress the motherboard.
Checking Jumper Settings
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 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.

The following illustration shows the location of the motherboard jumpers. Pin 1 is
labeled.

(Optional)
1. To avoid the system unstability after clearing CMOS, we recommend
users to enter the main BIOS setting page to “Load Optimal Defaults”
and then “Save Changes and Exit”.
2. Make sure the power supply provides enough 5VSB voltage before
selecting the 5VSB function.
3. It is required that users place the USBPWR_F & USBPWR_R cap onto
2-3 pin rather than 1-2 pin as default if you want to wake up the computer by USB/PS2 KB/Mouse.

Connecting Case Components
After you have installed the motherboard into a case, you can begin connecting the
motherboard components. Refer to the following:
1 Connect the CPU cooling fan cable to CPU_FAN1.
2 Connect the standard power supply connector to ATX_POWER1.
3 Connect the case speaker cable to SPK.
4 Connect the case switches and indicator LEDs to the F_PANEL.
5 Connect the system cooling fan connector to SYS_FAN1.
6 Connect the auxiliary case power supply connector to ATX12V1.
Connecting 24-pin power cable
Users please note that the 24-pin power cable can be connected to the
ATX_POWER1 connector.
With ATX v2.x power supply, users please
note that when installing 24-pin power
cable, the latches of power cable and the
ATX_POWER1 match perfectly.
