    Got myself a HP640 and want use the DMI (NBDmitFit tool) in order to fidle with the laptop name etc

    When I boot using my FreeDOS USB, the tool complains that this MPM (Manufacturers Programming Mode) is not unlocked. After some research, I found this needs a SMC.bin file with is prepped based on unique laptop basis (e.g. UUID or serial). Do I really need to take the hassle and go through HP in order to prepare this for me (if they do, since this is way out warranty...) or is there another way around this?

    p.s. version of the NBDmitFit tool I tried was one of the latest ones (2.12)

    So you basically got external hardware (reader) for the BIOS and then re-flash modded BIOS - I see.

    There is no other way (via software only) that I could attempt?
    As I said at the begining this is something I d like to learn to do for fun - it's not like I need a password unlock or any other specific mod.
    But with that MPM in place, I can't attempt any :(
    There's also tons of tools in another BIOS thread, but not sure which is applicable (if any!). Don't feel like bricking my laptop!
