1.2 Choosing a Computer Chassis

Choose a chassis big enough to install this motherboard.

As some features for this motherboard are implemented by cabling connectors on the motherboard to indicators and switches or buttons on the chassis, make sure your chassis supports all the features required.

If there is a possibility of adopting some more hard drives, make sure your chassis has sufficient power and space for them.

Most chassis have alternatives for I/O shield located at the rear panel. Make sure the I/O shield of the chassis matches the I/O port configuration of this motherboard. You can find an I/O shield specifically designed for this motherboard in its package.

1.3 Installing Motherboard

Most computer chassis have a base with many mounting holes to allow the motherboard to be securely attached, and at the same time, prevent the system from short circuits. There are two ways to attach the motherboard to the chassis base: (1) with studs, or (2) with spacers.

Basically, the best way to attach the board is with studs. Only if you are unable to do this should you attach the board with spacers. Line up the holes on the board with the mounting holes on the chassis. If the holes line up and there are screw holes, you can attach the board with studs. If the holes line up and there are only slots, you can only attach with spacers. Take the tip of the spacers and insert them into the slots. After doing this to all the slots, you can slide the board into position aligned

with slots. After the board has been positioned, check to make sure everything is OK before putting the chassis back on.

Always power off the computer and unplug the AC power cord before adding or removing any peripheral or component. Failing to so may cause severe damage to your motherboard and/or peripherals. Plug in the AC power cord only after you have carefully checked everything.

To install this motherboard:

1.Locate all the screw holes on the motherboard and the chassis base.

2.Place all the studs or spacers needed on the chassis base and have them tightened.

3.Face the motherboard’s I/O ports toward the chassis’s rear panel.

4.Line up all the motherboard’s screw holes with those studs or spacers on the chassis.

5.Install the motherboard with screws and have them tightened.

To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if they are already fastened on the chassis base and are without mounting-holeson the motherboard to align with.

This side faces the chassis’s rear panel.

1.4 Checking Jumper Settings

For a 2-pinjumper, plug the jumper cap on both pins will make it CLOSE (SHORT). Remove the jumper cap, or plug it on either pin (reserved for future use) will leave it at OPEN position.

SHORT

OPEN

OPEN

For a 3-pinjumper, pin 1~2 or pin 2~3 can be shorted by plugging the jumper cap in.

Pin 1~2 SHORT

Pin 2~3 SHORT

1.4.1CMOS Memory Clearing Header and Backup Battery

The time to clear the CMOS memory occurs when (a) the CMOS data becomes corrupted, (b) you forgot the supervisor or user password preset in the BIOS menu, (c) you are unable to boot-upthe system because the CPU ratio/clock was incorrectly set in the BIOS menu, or (d) whenever there is modification on the CPU or memory modules.

This header uses a jumper cap to clear the CMOS memory and have it reconfigured to the default values stored in BIOS.

Pin-2andpin-3shorted (Default):Normal operation.

Pin-1andpin-2shorted:Clear CMOS memory.

To clear the CMOS memory and load in the default values:

1.Power off the system.

2.Set pin-1andpin-2shorted by the jumper cap. Wait for a few seconds. Set the jumper cap back to its default settings---pin-2andpin-3shorted.

3.Power on the system.

4.For incorrect CPU ratio/clock settings in the BIOS, press <Del> key to enter the BIOS setup menu right after powering on system.

5.Set the CPU operating speed back to its default or an appropriate value.

6.Save and exit the BIOS setup menu.

CMOS Backup Battery:

An onboard battery saves the CMOS memory to keep the BIOS information stays on even after disconnected your system with power source. Nevertheless, this backup battery exhausts after some five years. Once the error message like “CMOS BATTERY HAS FAILED” or “CMOS checksum error” displays on monitor, this backup battery is no longer functional and has to be renewed.

I-S71

To renew the backup battery:

1.Power off the system and disconnect with AC power source.

2.Remove the exhausted battery.

3.Insert a new CR2032 or equivalent battery. Pay attention to its polarity. The “+” side is its positive polarity.

4.Connect AC power source and power on the system.

5.Enter the BIOS setup menu. Reconfigure the setup parameters if necessary.

CAUTION:

Danger of explosion may arise if the battery is incorrectly renewed.

Renew only with the same or equivalent type recommended by the battery manufacturer.

Dispose of used batteries according to the battery manufacturer’s instructions.

1.5 Connecting Chassis Components

1.5.1 ATX Power Connectors

These connectors provide the connection from an ATX power supply. As the plugs from the power supply fit in only one orientation, find the correct one and push firmly down into these connectors.

ATX 24-PinPower Connector:

The power supply with 20-pinor24-pincables can both be connected to this24-pinconnector. Connect frompin-1for either type. However, a20-pinpower supply may cause the system unstable or even unbootable for the sake of insufficient electricity. A minimum power of 300W or higher is recommended.

ATX 12V 4-PinPower Connector:

This connector supplies power to CPU. The system will not start without connecting power to this one.

1.5.2 Front Panel Switches and Indicators Headers

This header is used for connecting switches and LED indicators on the chassis front panel.

Watch the power LED pin position and orientation. The mark “+” align to the pin in the figure below stands for positive polarity for the LED connection. Please pay attention when connecting these headers. A wrong orientation will only result in the LED not lighting, but a wrong connection of the switches could cause system malfunction.

1.5.3 FAN Power Connectors

These connectors each provide power to the cooling fans installed in your system.

CPU_FAN1: CPU Fan Power Connector

SYS_FAN1: System Fan Power Connector

These fan connectors are not jumpers. DO NOT place jumper caps on these connectors.

1.6 Installing Hardware

DO NOT scratch the motherboard when installing hardware. An accidental scratch of a tiny surface-mountcomponent may seriously damage the motherboard.

In order to protect the contact pins, please pay attention to these notices:

1.A maximum 20 cycles of CPU installation is recommended.

2.Never touch the contact pins with fingers or any object.

3.Always put on the cap when the CPU is not in use.

1.6.1 CPU Socket 775

The installation procedures vary with different types of CPU fan-and-heatsinkassembly. The one shown here is served for demo only. For detailed information on how to install the one you bought, refer to its installation guidelines.

1.Place the board so that the lever-hookof the socket is on your left side. Use your left thumb and forefinger to hold the lever hook, pull it away from the retention tab. Rotate the lever to fully open position.

2.Use your right-thumbto raise the load plate. Lift it up to fully open position.

3.Use your right thumb and forefinger to grasp the CPU package. Be sure to grasp on the edge of the substrate, and face the Pin-1indicator toward thebottom-leftside. Aim at the socket and place the CPU package vertical down into the socket.

4.Visually inspect if the CPU is seated well into the socket. The alignment key must be located in the notch of package.
