    Thanks for responding. I saw in another post that perhaps it would be possible to generate new RSA keys (public and private) and then re-signing the modded bios with those keys. I looked at the bios BIN file using a hex editor and see strings like these: -----BEGIN PUBLIC KEY-----..MIIB and -----END PUBLIC KEY--.

    Seems in between those statements are the public keys.

    Not sure where the private key is in the bios. I also saw " SECURE_HP_SIGNATURE M40 v01.12" and "SIG_END" strings, but in between those characters did not look like your typical RSA private key signature. How possible is it to replace those with a new set, if that's what the checker is checking during boot?

    I used the official bios.
    I also diffed both files (off. bios and my backup): didn't report anything. so they seem to be the same anyways.
