Before you proceed

Take note of the following precautions before you install motherboard components or change

any motherboard settings.

•

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, ensure that the ATX power supply is

switched off or the power cord is detached from the power supply. Failure to do so may

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

ASUS MyLogo2™

This feature allows you to convert your favorite photo into a 256-color

boot logo for a more colorful and vivid image on your screen.

ASUS CrashFree BIOS 3

ASUS CrashFree BIOS 3 is an auto-recovery tool that allows you to

restore a corrupted BIOS file using the bundled support DVD or USB

flash disk that contains the latest BIOS file.

ASUS EZ Flash 2

ASUS EZ Flash 2 is a utility that allows you to update the BIOS without

using an OS-based utility.

C.P.R. (CPU Parameter Recall)

The BIOS C.P.R. feature automatically restores the CPU default settings

when the system hangs due to overclocking failure. C.P.R. eliminates the

need to open the system chassis and clear the RTC data. Simply shut

down and reboot the system, and the BIOS automatically restores the

CPU parameters to their default settings.

ErP ready

The motherboard is European Union´s Energy-related Products (ErP)

ready, and ErP requires products to meet certain energy efficiency

requirements in regards to energy consumptions. This is in line with

ASUS vision of creating environment-friendly and energy-efficient

products through product design and innovation to reduce carbon

footprint of the product and thus mitigate environmental impacts.
