1.2 Motherboard Layout

2. Hardware Setup
In this chapter we will elaborate all the information you need upon installing this motherboard to your computer system. 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.

Hardware Setup

2.1 Choosing a Computer Chassis
This motherboard carries an mATX form factor of 244 x 244 mm. 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 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.

2.2 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. use studs, or 2. use spacers In principle, the best way to attach the board is to use 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.
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 motherboards I/O ports toward the chassiss rear panel. 4. Line up all the motherboards 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-holes on the motherboard to align with.
2.3 Checking Jumper Settings
For a 2-pin jumper, 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.
Face the chassiss rear panel. OPEN
For 3-pin jumper, pin 1~2 or pin 2~3 can be shorted by plugging the jumper cap in.

Pin 1~2 SHORT

Pin 2~3 SHORT
2.3.1 CMOS 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-up the system because the CPU ratio/clock was incorrectly set in the BIOS menu. This header uses a jumper cap to clear the CMOS memory and have it reconfigured to the default values stored in BIOS.
Pins 2 and 3 shorted (default): Normal operation. Pins 1 and 2 shorted: Clear CMOS memory.
To clear the CMOS memory and load in the default values: 1. Power off the system. 2. Set pin 1 and pin 2 shorted by the jumper cap. Wait for a few seconds. Set the jumper cap back to its default settings --- pin 2 and pin 3 shorted. 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.
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 manufacturers instructions.
2.4 Connecting Chassis Components
2.4.1 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.
2.4.2 FAN Power Connectors
These connectors each provide power to the cooling fans installed in your system. CPU_FAN: Power connector for CPU cooling fan SYS_FAN: System Fan Power Connector PWR_FAN: Auxiliary Fan Power Connector
These fan connectors are not jumpers. DO NOT place jumper caps on these connectors.
2.4.3 Front Panel Switches & 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 to connect these headers. A wrong orientation will only cause the LED not lighting, but a wrong connection of the switches could cause system malfunction.

2.5 Installing Hardware

DO NOT scratch the motherboard when installing hardware. An accidentally scratch of a tiny surface-mount component 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.

2.5.1 CPU Socket 775

1. Place the board so as to let the lever-hook of 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 thumb on the bottom-right side of the load plate and 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-1 indicator toward the bottom-left side. 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.
5. Use your left hand to hold the load plate, and use your right thumb to peel the cap off.
The cap plays an important role in protecting contact pins. In order to prevent bent pin, PUT ON the cap after operation or testing.
6. Lower the plate onto the CPU package. Engage the load lever while gently pressing down the load plate.
7. Secure the lever with the hook under retention tab.
8. Place the heatsink and fan assembly onto the socket. Align the four fasteners toward the four mounting holes on the motherboard.
9. Press each of the four fasteners down into the mounting holes. Rotate the fastener clock-wise to lock the heatsink and fan assembly into position.
10. Attach the four-pin power plug from the heatsink and fan assembly to the CPU FAN connector.
The installation procedures vary with different types of CPU fan-and-heatsink assembly. 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. A higher fan speed will be helpful for better airflow and heat-dissipation. Nevertheless, stay alert to touch any heatsink since the high temperature generated by the working system is still possible.

2.5.2 DDR Memory Slots

This motherboard provides two 184-pin DDR DIMM slots for un-buffered and non-ECC modules, memory size expansible up to 2GB (DDR400). DIMM DIMM Module 256MB, 512MB, 1GB 256MB, 512MB, 1GB Total System Memory Total Memory 256MB ~ 1GB 256MB ~ 1GB 256MB ~ 2GB
Power off the computer and unplug the AC power cord before installing or removing memory modules. 1. Locate the DIMM slot on the board. 2. Hold two edges of the DIMM module carefully, keep away of touching its connectors. 3. Align the notch key on the module with the rib on the slot. 4. Firmly press the module into the slots until the ejector tabs at both sides of the slot automatically snaps into the mounting notch. Do not force the DIMM module in with extra force as the DIMM module only fit in one direction. 5. To remove the DIMM modules, push the two ejector tabs on the slot outward simultaneously, and then pull out the DIMM module. Static electricity can damage the electronic components of the computer or optional boards. Before starting these procedures, ensure that you are discharged of static electricity by touching a grounded metal object briefly.

5.1 Troubleshooting (How to Get Technical Support?)

5.1.1 Q & A

Q: Do I need to clear the CMOS before I use a new motherboard to assemble my new computer system? A: Yes, we highly recommend that you clear the CMOS before installing a new motherboard. Please move the CMOS jumper from its default 2-3 position to 1-2 for a few seconds, and then back. When you boot up your system for the first time, follow the instructions in the user's manual to load the optimized defaults. Q: If my system hangs when I update the BIOS or set the wrong CPU parameters, what should I do? A: Whenever you update the BIOS or if the system hangs due to wrong CPU parameters setting, always clear CMOS jumper before booting up again. Q: Why does the system fail to boot up again right after a mechanical power-off? A: Please keep a 30-second interval between each mechanical power On/Off. Q: Why does the system fail to boot up and nothing displays on the screen after I did some over-clocking or non-standard settings inside the BIOS? A: It should not cause hardware or permanent damage to motherboard when BIOS settings were changed from default to over-clocking or non-standard status. We suggest the following three troubleshooting methods to discharge CMOS data, recover the hardware default status, and then making the motherboard work again. There is no need to bother returning the motherboard to where you bought it from or go through an RMA process. Step 1. Switch off the power supply unit and then switch it on again after one minute. If there is no power-switch on the power supply unit, disconnect its power cord for one minute and then reconnect. Press and hold the <Insert> key on the keyboard, and press the power-on button to boot up system. If it works, release the <Insert> key and hit <Del> key to enter the BIOS setup page to apply the correct settings. If the situation remains the same, repeat the procedures in Step 1 for three times, or try Step 2. Step 2. Switch off the power supply unit or disconnect the power cord. Open the chassis cover. Locate the CCMOS jumper near the button battery. Change the jumper position from default 2-3 to 1-2 for one minute to discharge the CMOS data, and then put it back to default 2-3 position. Close the chassis and switch on the power supply unit or plug in the power cord. Press the power-on button to boot up system. If it works, hit <Del> key to enter the BIOS setup page to do the correct settings. If the situation remains the same, try Step 3. Step 3. The same procedure as Step 2, but while discharging the CMOS data, pull out the ATX power connectors from motherboard and remove the button battery during CMOS discharge. Q: How to get a quick response for my request on technical support? A: Please carry out a simple troubleshooting before sending Technical Support Form: System boot-up fails after the system had been assembled: Check the motherboards supporting specifications first to see if all the key components attached in your system can meet. To do so, you may: Remove all the unnecessary add-on devices (except the CPU, VGA card, DRAM, and Power Supply), and then reboot. If the trouble still exists, try another VGA card of different brand/model to see if the system will start. If the trouble still exists, try another memory module of different brand/model. If the trouble still exists, try another CPU and Power Supply. If the system runs successfully, shut it down and start re-installing the interface cards and devices that were previously installed in the system. Re-install and start the system one at a time until the system wont start. Malfunction in the OS: If the system hangs after resuming from S3 or some testing program, if the CPU cannot be recognized properly, if the display resolution mixed, or if a certain program cannot be executed, etc, you may:

Upgrade the motherboards latest BIOS version. Upgrade the add-on devices latest driver version. Check if there is any conflict in the Control Panel/System Properties.
