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, es-
tablish 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 by
the manufacturer.
• Dispose of used batteries according to local ordinance.

Chapter 2 - Hardware Installation
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 then 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 then power-on the system.

Clearing CMOS Data using the EZ Clear®Function
EZ Clear®bypasses the manual process of using a jumper to clear
the CMOS by simply using the reset and power buttons.
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 approxi-
mately 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.
