Safety information

Electrical safety

• To prevent electrical shock hazard, disconnect the power cable from the electrical outlet

before relocating the system.

• When adding or removing devices to or from the system, ensure that the power cables

for the devices are unplugged before the signal cables are connected. If possible,

disconnect all power cables from the existing system before you add a device.

• Before connecting or removing signal cables from the motherboard, ensure that all

power cables are unplugged.

• Seek professional assistance before using an adapter or extension cord. These devices

could interrupt the grounding circuit.

• Ensure that your power supply is set to the correct voltage in your area. If you are not

sure about the voltage of the electrical outlet you are using, contact your local power

company.

• If the power supply is broken, do not try to x it by yourself. Contact a qualied service

technician or your retailer.

Operation safety

• Before installing the motherboard and adding components, carefully read all the manuals

that came with the package.

• Before using the product, ensure all cables are correctly connected and the power

cables are not damaged. If you detect any damage, contact your dealer immediately.

• To avoid short circuits, keep paper clips, screws, and staples away from connectors,

slots, sockets and circuitry.

• Avoid dust, humidity, and temperature extremes. Do not place the product in any area

where it may be exposed to moisture.

• Place the product on a stable surface.

• If you encounter technical problems with the product, contact a qualied service

technician or your retailer.

Product introduction

1.1 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.

• 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.

Unplugthepowercordbeforeinstallingorremovingthemotherboard.Failuretodoso

can cause you physical injury and damage motherboard components.

• ASUS EZ Flash 3 supports USB devices, such as a USB ash disk, with FAT 32/16

format and single partition only.

• DO NOT shut down or reset the system while updating the BIOS to prevent system

boot failure!

2.1.3 ASUS CrashFree BIOS 3 utility

The ASUS CrashFree BIOS 3 is an auto recovery tool that allows you to restore the BIOS le

when it fails or gets corrupted during the updating process. You can restore a corrupted BIOS

le using the motherboard support DVD or a USB ash drive that contains the updated BIOS

le.

• Before using this utility, rename the BIOS le in the removable device into

PZ 270M P.CA P.

• The BIOS le in the support DVD may not be the latest version. Download the latest

BIOS le from the ASUS website at www.asus.com.

Recovering the BIOS

To recover the BIOS:

1. Turn on the system.

2. Insert the support DVD to the optical drive or the USB ash drive that contains the

BIOS le to the USB port.

3. The utility automatically checks the devices for the BIOS le. When found, the utility

reads the BIOS le and enters ASUS EZ Flash 3 utility automatically.

4. The system requires you to enter BIOS Setup to recover BIOS settings. To ensure

system compatibility and stability, we recommend that you press <F5> to load default

BIOS values.

DO NOT shut down or reset the system while updating the BIOS! Doing so can cause

system boot failure!

2.1.4 ASUS BIOS Updater
