    Please forgive my ignorance I am good at a lot of things but understanding bios mods is not one of them. My question is the following. I've read that when you want to know if your Bios is RSA Signed you run Phoenix Tools and if it says decrypted then you are screwed.

    Now, what about the bios under HPTOOLS Current Bios folder? There is a bios file 01793.bin and a 01793.sig, which to my understanding is used for recovery (I dont know). When I run Phoenix Tools on this it does not say decrypted. So is there a possibility to modify and re-flash this bios? Or is it still RSA Signed?

    Could you please point me in the right direction to understand this?

    Well the file next to bios is the name of the bios .bin file but a .sig extension. Like I said in the original post
    is 07193.bin and 07193.sig

    So it is still RSA signed ? Even though Phoenixtools does not say decrypted?

    Actually, the "signature" that makes everathing difficult is not the .SIG file... It the one (or two) in
    07193.bin!

    Actually, can you tell me, who exactly tells everyone that the "Decrypted" message from the
    phoenix tool automatically means: "signature -> you are screwed"?! I'm asking this because
    even without the ".SIG" file, you can still be screwed.
