ASUS has this WEIRD as hell thing going where it's BIOS Flashback only works on FAT32 USB sticks formatted specifically with FAT32 via CMD Diskpart... If you just right-click on USB drive, select FAT32, and then Quick Format, then ASUS Flashback will not work. Is there a tool that would do exactly what Diskpart does? Having type stuff to format USB drive is just too old-school...
