ASUS CrashFree BIOS

The ASUS CrashFree BIOS is an auto recovery tool that allows you to restore the BIOS file

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

file using the motherboard support DVD or a removable device that contains the updated

BIOS file.

•

The BIOS file in the support DVD may not be the latest version. Download the latest

BIOS file from the ASUS website at www.asus.com.

•

The removable devices that ASUS CrashFree BIOS support vary with motherboard

models. For motherboards without the floppy connector, prepare a USB flash disk before

using this utility.

Recovering the BIOS

To recover the BIOS:

1.

Turn on the system.

2.

Insert the support DVD to the optical drive or the removable device that contains the

BIOS file to the USB port or to the floppy disk drive, if supported.

3.

The utility automatically checks the devices for the BIOS file. When found, the utility

reads the BIOS file and starts flashing the corrupted BIOS file.

4.

Turn off the system after the utility completes the updating process and turn on again.

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

system boot failure!

Ensure to load the BIOS default settings to ensure system compatibility and stability. Select

the

Load Setup Defaults

item under the Exit menu. Refer to section

2.8 Exit menu
