ASUS CrashFree BIOS 3
The ASUS CrashFree BIOS 3 utility is an auto recovery tool that allows you to restore the
BIOS le when it fails or gets corrupted during the updating process. You can restore a
corrupted BIOS le using the motherboard support DVD or a USB ash drive that contains
the BIOS le.
The BIOS le in the motherboard support DVD may be older than the BIOS le published
on the ASUS ofcial website. If you want to use the newer BIOS le, download the le at
http://support.asus.com and save it to a USB ash drive.
Recovering the BIOS
To recover the BIOS:
1. Turn on the system.
2. Insert the motherboard support DVD to the optical drive, or the USB ash drive
containing the BIOS le to the USB port.
3. The utility automatically checks the devices for the BIOS le. When found, the utility
reads the BIOS le and enters ASUS EZ Flash 2 automatically.
4. The system requires you to enter BIOS Setup to recover the BIOS setting. 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!
ASUS BIOS Updater
The ASUS BIOS Updater allows you to update the BIOS in DOS environment. This utility also
allows you to copy the current BIOS le 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.
Before updating BIOS

single partition.
2. Download the latest BIOS le and BIOS Updater from the ASUS website at
http://support.asus.com and save them on the USB ash drive.
