I have an AsRock B550M-HDV mobo, and unfortunately, all the tools I’ve tried to use have failed. There is still one hope left for me though: AsRock offers BIOS downloads through their website, but in the form of an instant flash file. Does anybody know how to extract the contents of this file?
Edit by Fernando: Thread title customized and shortened
Well, I immediately found my answer in the form of cpu-z. Now I just need to convert the .txt file to a binary file…
Update part 2: While CPU-Z did dump a BIOS, it seems to have dumped the CSM. So I’m back to square one

Welcome to the Win-Raid Forum!
I do not really understand your problem. After having unzipped the latest downloaded BIOS you get a file named B55HDV_3.xx. That is the “pure” BIOS file, which can easily been opened by any modern AMI UEFI Tool like the UEFITool 0.28.0.
Look here:
What do you want to get extracted? The UEFITool will do it
I feel so dumb right now. How did I not think of trying that. Thanks for the help though!
Hmm, the part I’m interested in for reverse engineering purposes, the reset vector, is blocked out with all 0xff. I guess it’s back to the drawing board
It was not my intention to mislead, as that was my original goal. I have updated it to more accurately reflect what I am trying to achieve
