Introduction

Static Electricity Precautions

It is quite easy to inadvertently damage your PC, system board, components or devices even before installing them in your system unit. Static electrical discharge can damage computer components without causing any signs of physical damage. You must take extra care in handling them to ensure against electrostatic build-up.

1. To prevent electrostatic build-up, leave the system board in its anti-static bag until you are ready to install it.

2. Wear an antistatic wrist strap.

3. Do all preparation work on a static-free surface.

4. Hold the device only by its edges. Be careful not to touch any of the components, contacts or connections.

5. Avoid touching the pins or contacts on all modules and connectors. Hold modules or connectors by their ends.

Important:

Electrostatic discharge (ESD) can damage your processor, disk drive and other components. Perform the upgrade instruction procedures described at an ESD workstation only. If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal part of the system chassis. If a wrist strap is unavailable, establish and maintain contact with the system chassis throughout any procedures requiring ESD protection.

Safety Measures

To avoid damage to the system:

•Use the correct AC input voltage range

To reduce the risk of electric shock:

• Unplug the power cord before removing the system chassis cover for installation or servicing. After installation or servicing, cover the system chassis before plugging the power cord.

Battery:

• Danger of explosion if battery incorrectly replaced.

• Replace only with the same or equivalent type recommend

the manufacturer.

• Dispose of used batteries according to local ordinance.

Jumper Settings

If you encounter the following,

a) CMOS data becomes corrupted. b) You forgot the supervisor or user password. c) The overclocked settings in the BIOS resulted to the system’s in-

stability or caused system boot up problems.

you can reconfigure the system with the default values stored in the ROM BIOS.

To load the default values stored in the ROM BIOS, please follow the steps below.

1. Power-off the system and unplug the power cord.

2. Set JP2 pins 2 and 3 to On. Wait for a few seconds and set JP2 back to its default setting, pins 1 and 2 On.

3. Now plug the power cord and power-on the system.

Important:

EZ Clear® is supported only if standby power is present in the system.

To use EZ Clear®:

1. Make sure the standby power is present.

2. Using the EZ touch switches on the system board, first press the Reset button then the Power button simultaneously for approximately 4 seconds.

If the system board is already enclosed in a chassis, apply the same method using the Reset button and Power button located at the front panel of the chassis.

3. After 4 seconds, release the power button first then the Reset button.

4. The CMOS will restore the clock settings back to their default values.

Floppy Disk Drive Connector

The 90o floppy disk drive connector is used to connect a floppy drive. It has a keying mechanism to prevent improper floppy cable installation. Inser t one end of the floppy cable into this connector and the other end-most connector to the floppy drive. The colored edge of the cable should be aligned with pin 1 of this connector.

IDE Disk Drive Connector

The IDE disk drive connector is used to connect 2 IDE disk drives. It has a keying mechanism to prevent improper IDE cable installation. An IDE cable have 3 connectors on them, one that plugs into this connector and the other 2 connects to IDE devices. The connector at the end of the cable is for the Master drive and the connector in the middle of the cable is for the Slave drive. The colored edge of the cable should be aligned with pin 1 of this connector.

Note:

When using two IDE drives, one must be set as the master and the other as the slave. Follow the instructions provided by the drive manufacturer for setting the jumpers and/or switches on the drives.

IrDA and CIR Connectors

These connectors are used to connect an IrDA module and/or CIR module.

Note:

The sequence of the pin functions on some IrDA/CIR cable may be reversed from the pin function defined on the system board. Make sure to connect the cable connector to the IrDA/ CIR connector according to their pin functions.

You may need to install the proper drivers in your operating system to use the IrDA/CIR function. Refer to your operating system’s manual or documentation for more information.

Serial (COM) Connector

The serial (COM) connector is used to connect modems, serial printers, remote display terminals, or other serial devices. Your COM port may come mounted on a card-edge bracket.

DRAM Power LED

This LED will light when the system’s power is on.

Standby Power LED

This LED will light when the system is in the standby mode.

Diagnostic LED

The Diagnostic LED displays POST codes. POST (Power-On Self Tests) which is controlled by the BIOS is performed whenever you power-on the system. POST will detect the status of the system and its components. Each code displayed on the LED corresponds to a certain system status.

Warning:

When the DRAM Power LED and/or Standby Power LED lit red, it indicates that power is present on the DIMM sockets and/or PCI slots. Power-off the PC then unplug the power cord prior to installing any memory modules or add-in cards. Failure to do so will cause severe damage to the motherboard and components.

Power Connectors

Use a power supply that complies with the ATX12V Power Supply Design Guide Version 1.1. An ATX12V power supply unit has a standard 24-pin ATX main power connector that must be inserted into this connector.

Your power supply unit may come with an 8-pin or 4-pin +12V power connector. The +12V power enables the delivery of more +12VDC current to the processor’s Voltage Regulator Module (VRM). If available, it is preferable to use the 8-pin power; otherwise connect a 4-pin power to this connector.

The FDD-type power connectors are additional power connector.s If you are using more than one graphics cards, we recommend that you plug power cables from your power supply unit onto the 5V/ 12V power connectors. This will provide more stability to the entire system. The system board will still work even if the additional power connector is not connected.

The system board requires a minimum of 300 Watt power supply to operate. Your system configuration (CPU power, amount of memory, add-in cards, peripherals, etc.) may exceed the minimum power requirement. To ensure that adequate power is provided, we

strongly recommend that you use a minimum of 400 Watt (or greater) power supply.

Important:

Insufficient power supplied to the system may result in instability or the add-in boards and peripherals not functioning properly. Calculating the system’s approximate power usage is important to ensure that the power supply meets the system’s consumption requirements.

The power connectors from the power supply unit are designed to fit the 24-pin and 8-pin connectors in only one orientation. Make sure to find the proper orientation before plugging the connectors.

Restarting the PC

Normally, you can power-off the PC by:

1. Pressing the power button at the front panel of the chassis.

2. Pressing the power switch that is on the system board (note: not all system boards come with this switch).

If for some reasons you need to totally cut off the power supplied to the PC, switch off the power supply or unplug the power cord. Take note though that if you intend to restart it at once, please strictly follow the steps below.

1. The time where power is totally discharged varies among power supplies. It's discharge time is highly dependent on the system's configuration such as the wattage of the power supply, the sequence of the supplied power as well as the number of peripheral devices connected to the system. Due to this reason, we strongly recommend that you wait for the Standby Power LED (refer to the “LEDs” section in this chapter for the location of the Standby Power LED) to lit off.

2. After the Standby Power LED has lit off, wait for 6 seconds before powering on the PC.

If the system board is already enclosed in a chassis which apparently will not make the Standby Power LED visible, wait for 15 seconds before you restore power connections. 15 seconds is approximately the time that will take the LED to lit off and the time needed before restoring power.

The above will ensure protection and prevent damage to the motherboard and components.
