It works the same way as if you are Updating your bios. Just put the bios version you want on a USB stick, and use your flashback button. Your manual should also explain the different methods too.

You need to be IN your bios to flash it from the USB stick. This info is from your manual. Hope this helps you.

If you are not sure how to downgrade your bios, you should leave it alone maybe, as you could make your board unable to boot up. Or maybe take it to someone that can do it for you. Just a suggestion thork. Hope everything turns out well. Mike.

If you read the 2nd msg I posted to you, I explained it to you. Downgrading your bios works exactly same way as Upgrading.

There is a way to update the BIOS using a BIOS flashing utility and a bootable USB disk with that utility and the BIOS file copied to the root folder. I suggest to go the the following win-raid forum and ask there, explaining your motherboard model:

Actually if you look around there should be a thread that has the flashing tool and guide on how to flash your BIOS
