Hardware Setup 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. 2.1 Choosing a Computer Chassis This motherboard carries an mA

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

Hardware Setup 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 o

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. Re

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. Pin Definition Pin

Hardware Setup 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

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 wi
