My buddy bought an HP ZBook second hand and it had a bios pwd. He extracted the bios chips in an effort to bypass the bios pwd however it didn’t work and I’m convinced he simply didn’t have a valid set of files for the chips(my assumption) what I really need is 2 good files for It.. also will a cheap Ch341 do the trick if I’m careful and verify the chip prior to reinstallation? Thought I heard somewhere that the 2nd bios needed a different programmer?
