ASUS CrashFree BIOS 3 utility

The ASUS CrashFree BIOS 3 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 USB flash drive that contains the updated BIOS

file.

•

Before using this utility, rename the BIOS file in the removable device into

F1A75MLE.ROM

.

•

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.

Recovering the BIOS

To recover the BIOS:

1.

Turn on the system.

2.

Insert the support DVD to the optical drive or the USB flash drive that contains the

BIOS file to the USB port.

3.

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

reads the BIOS file and enters ASUS EZ Flash 2 utility automatically.

4.

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

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

BIOS values.

and then press <Enter>.
