    Lenovo ThinkCentre M75q Gen5 bios password

    Hello!

    I'm trying to remove the bios password of an Lenovo ThinkCentre M75q Gen5
    Unfortunately i cant find many resources about the Gen5 or the bios chip.

    Bios chip is XMC 25RU256CXIQ.
    SN is GM0QDZ77

    Let me know if there is an issue with the attached bios dump, as this is my first attempt and i dont have a wson8 clip
    Would be great if someone could decrypt the password from the dump, but if thats not possible i can attempt to flash the chip (hoping my crappy solder job works)
