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 

H81MC.CAP.

• 

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.

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 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!

The ASUS BIOS Updater allows you to update BIOS in a DOS environment. This utility also 

allows you to copy the current BIOS file that you can use as a backup when the BIOS fails or 

gets corrupted during the updating process.

The succeeding utility screens are for reference only. The actual utility screen displays may 

not be same as shown.

1. 

Prepare the motherboard support DVD and a USB flash drive formatted using 

FAT32/16 on a single partition.

2. 

Download the latest BIOS file and BIOS Updater from the ASUS website at

http://support.asus.com and save them on the USB flash drive.

NTFS is not supported under DOS environment. Do not save the BIOS file and BIOS 

Updater to a hard disk drive or USB flash drive in NTFS format.

3. 

Turn off the computer and disconnect all SATA hard disk drives (optional).
