Hey, I'm thinking about upgrading my BIOS and found "flashrom" in DEBIAN-repositories. Running a "read" on the builtin BIOS I saw the request for sending you some information - so here you are. Does "guesswork" mean, it might be unsafe to use this software on this board/bios?
Thanks for your work! Greetings, Volker

Hi,
well, Nvidia does not provide the required documentation so we had to reverse engineer the interface and you never know if everything works as expected. That said, I think it is pretty safe to try. There was also a successful write on a NF-M2S which is probably not too much different regarding the parts involved in flashing.
