Motherboard information

2.1 Before you proceed

Take note of the following precautions before you install motherboard components

or change any motherboard settings.

CAUTION!

• Unplug the power cord from the wall socket before touching any

component.

• Before handling components, use a grounded wrist strap or touch a safely

grounded object or a metal object, such as the power supply case, to avoid

damaging them due to static electricity.

• Hold components by the edges to avoid touching the ICs on them.

• Whenever you uninstall any component, place it on a grounded antistatic

pad or in the bag that came with the component.

• Before you install or remove any component, always remove the AC power

by unplugging the power cord from the power outlet. Failure to do so may

cause severe damage to the motherboard, peripherals, or components.

Place this side

towards the rear

of the chassis

NOTE: Place four screws into the holes indicated by circles to secure the

motherboard to the chassis.

CAUTION! Do not overtighten the screws! Doing so can damage the

motherboard.

NOTE: The audio codec may vary between motherboards, please consult

your sales window for the motherboards’ exact codec type.

2.5 Jumpers

1. Clear RTC RAM (2-pin CLRTC)

This header allows you to clear the CMOS RTC RAM data of the system

setup information such as date, time, and system passwords.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. Use a metal object such as a screwdriver to short the two pins.

3. Plug the power cord and turn ON the computer.

4. Hold down the <Del> key during the boot process and enter BIOS setup

to re-enter data.

NOTE: If the steps above do not help, remove the onboard battery and move

the jumper again to clear the CMOS RTC RAM data. After clearing the CMOS,

reinstall the battery.

2. Chassis intrusion header (4-1 pin_CHASSIS)

This header is for a chassis-mounted intrusion detection sensor or switch. Connect

one end of the chassis intrusion sensor or switch cable to this connector. The

chassis intrusion sensor or switch sends a low-level signal to this connector

when a chassis component is installed. The signal is then generated as a chassis

intrusion event.
