The ASUS CrashFree BIOS 3 utility 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 BIOS file.

The BIOS file in the motherboard support DVD may be older than the BIOS file published 

on the ASUS official website. If you want to use the newer BIOS file, download the file at 

http://support.asus.com and save it to a USB flash drive.

To recover the BIOS:
1. 

Turn on the system.

2. 

Insert the motherboard support DVD to the optical drive, or the USB flash drive 

containing 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 automatically.
