Chapter 3
3.4 ASUS CrashFree BIOS 3
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 a USB flash drive that contains the BIOS file.
Recovering the BIOS
1. Download the latest BIOS version for this motherboard from
whttps://www.asus.com/support/.
2. Rename the BIOS file as ASUS.CAP or MZ790H.CAP and copy the renamed BIOS
file to a USB flash drive.
3. Turn on the system.
4. Insert the USB flash drive containing the BIOS file to a USB port.
5. The utility automatically checks the devices for the BIOS file. When found, the utility
reads the BIOS file and enters ASUS EZ Flash 3 automatically.
6. 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!
