ASUS P7P55D Deluxe 3-1

3.1 Knowing BIOS

BIOS (Basic Input and Output System) stores system hardware settings such as storage

device conguration, overclocking settings, advanced power management, and boot device

conguration that are needed for system startup in the motherboard CMOS. In normal

circumstances, the default BIOS settings apply to most conditions to ensure optimum

performance. We recommend that you not change the default BIOS settings except in

the following circumstances:

• An error message appears on the screen during the system bootup and requests you to

run the BIOS Setup.

• You have installed a new system component that requires further BIOS settings or

update.

3.2 Updating BIOS

The ASUS website publishes the latest BIOS versions to provide enhancements on system

stability, compatibility, or performance. However, BIOS updating is potentially risky. If there

is no problem using the current version of BIOS, DO NOT manually update the BIOS.

Inappropriate BIOS updating may result in the system’s failure to boot. Carefully follow the

instructions of this chapter to update your BIOS if necessary.

Visit the ASUS website at www.asus.com to download the latest BIOS le for this

motherboard.

The following utilities allow you to manage and update the motherboard BIOS setup program.

1. ASUS Update: Updates the BIOS in Windows

environment.

2. ASUS EZ Flash 2: Updates the BIOS using a USB ash disk.

3. ASUS CrashFree BIOS 3 utility: Restores the BIOS using the motherboard support

DVD or a USB ash drive when the BIOS le fails or gets corrupted.

Refer to the corresponding sections for details on these utilities.

Save a copy of the original motherboard BIOS le to a USB ash drive in case you need

to restore the BIOS in the future. Copy the original motherboard BIOS using the ASUS

Update utility.

Inappropriate settings of the BIOS may result to instability or failure to boot. We strongly

recommend that you change the BIOS settings only with the help of a trained service

personnel.
