    totally wrong.. computer BIOS.bin is for a programmer to write on chip..
    keep dreaming of the magical SMC.bin

    Hi. I have hp zbook studio g5 with no password lock but persistence module permanently enabled.
    I dumped the content of mx25l256 in wson package and replaced “VSS2” Store” with a blank one from downloaded on product support page bios.
    Now computrace is permanently disabled but laptop asks to restore MUD data, however “restore” button is not active.

    Hi,
    may i ask if its possible to remove bios pw without soldering ?

    HP8570p

    got finally a working MB for my 8570 from ebay but locked

    should i give it a try with the mazzif tool i bought some years ago ? but it is stated as not supported **70 models.

    br max

    Edit, no success with HPBR as expected, if i need to remove the chip, is there a tutorial i can follow for reprogramming and info for the needed files ?

    Update: no more need, got password from seller.....

    Hi,

    i am actually waiting for the clip beeing delivered, as i already have a raspberry Pi3 i would give it a try to read out the chip from 8570p.
    As i cannot post a picture actually, can anyone send a picture or schematic with the correct chip marked ?
