890fx Deluxe5 BIOS update issues

I've seen where people have been able to update their BIOS to version L2.01F in order to get newer video cards to work.  I recently purchased an MSI R9 390x w/8Gigs of memory and when I plug it into the PCI slot I get nothing on the screen.  The motherboard shows the typical error that there's something going on with the video.

I was able to update the motherboard BIOS from version 1.2 to 2.0, but I had to use the windows version because the Instant Flash would never find the files on the USB stick.  After the update, I still received the same errors and that's when I found that I needed to move on to the beta BIOS update in order to get things to work.  But here's the problem, no matter what I do, I cannot get the Instant Flash updater in the BIOS to see the file on my USB stick.  I constantly get "no image file detected" when I select Instant Flash.

Hey, I fully understand 

Yes, I extracted the update file from the .zip file and placed just the extraxted BIOS update file on the USB stick(s).

The link you have provided for the Deluxe5 board is the same location that I used for downloading the Beta BIOS file.  I did double check and the file I downloaded is a match to yours: 890FXD52.01F.  The file size is the same as well.

I'm just scratching my head on this one.  Should I try using plain old FAT formatting or maybe seeing if I put the BIOS on a CD to see if it'll recognize?
