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 update a corrupted BIOS

file using the motherboard support DVD, a floppy disk, or a USB flash disk that contains the

updated BIOS file.

•

Prepare the motherboard support DVD, the floppy disk, or the USB flash disk containing

the updated motherboard BIOS before using this utility.

•

Always connect the SATA cable to the SATA1 / SATA 2 connector. Otherwise, the utility

will not function.

Recovering the BIOS

To recover the BIOS:

1.

Turn on the system.

2.

Insert the floppy disk, support DVD, or USB flash disk containing the BIOS file to the

disk drive or port.

3.

The utility displays the following message and automatically checks the floppy disk,

support DVD, or USB flash disk for the BIOS file.

•

Only the USB flash disk with FAT 32/16 format and single partition supports ASUS

CrashFree BIOS 3. The device size should be smaller than 8GB.

•

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

system boot failure!

4.

Restart the system after the utility completes the updating process.

•

The utility automatically checks the floppy disk first. If no floppy disk is found, the utility

then checks the optical drive and the USB flash disk.

•

The recovered BIOS may not be the latest BIOS version for this motherboard. Download

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