I see the latest bios is 0403 on Asus.com. I downloaded it and used the tools in the bios to attempt to flash it and it says it is not a valid file type. I had the .ROM saved in the root of my C drive (which is a RAID1 miror). I'm not sure if that makes a difference or not. The Bios update tool was able to browse my C drive without any issues.
I can't find an Asus Update utility for Windows.
Do I have to install the whole Asus suite of applications? I would prefer to avoid that.
