    Maximus X Hero: Bios update error: Selected file is not a proper BIOS!

    Hello everyone!

    I went into ASUS EZ Flash 3 Utility and attempted to update my BIOS to 1401. But I receive the following message: Selected file is not a proper BIOS!

    I downloaded the file onto a 2GB USB flash drive and connected to a USB port on back of motherboard. The file listed is: ROG-MASIMUS-X-HERO-ASUS-1401.CAP

    Was I supposed to modify this file or do something else in order to properly update my BIOS? All help appreciated!

    Thank you!

    I wanted to give an update: I already formatted the USB flash drive in FAT32, also downloaded another file from website in case first was corrupt. I tried different USB ports.

    Any other ideas??

    I made the stupid mistake of downloading the wrong BIOS file, there are two different BIOS files for the Maximus X Hero and Maximus X Hero (WI-FI AC). I have the latter of the two.
