ROG Crosshair IV Formula 3-5
3.1.3 ASUS CrashFree BIOS 3 utility
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 ofcial website. If you want to use the newer BIOS le,
download the le at 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 starts ashing the corrupted BIOS le.
4. Turn off the system after the utility completes the updating process and
power on again.
5. The system requires you to enter BIOS Setup to recover BIOS setting. To
ensure system compatibility and stability, we recommend that you press
<F2> to load default BIOS values.
DO NOT shut down or reset the system while recovering the BIOS! Doing so
can cause system boot failure!
