    You need to use LVar32.exe/LVar64.exe

    EEPROM.EXE is for Compal ODM systems. LVar32/64 is for LCFC ODM.

    ODM = Original Design Manufacturer

    When you buy a Dell/HP/Lenovo system you're actually buying a device that was manufactured by an ODM

    Quanta
    Compal
    Foxconn
    Pegatron
    LCFC
    Inventec
    Bitland

    The big PC vendors use a variety of them for their systems so one system in the same family might be made by Compal and another might be made by LCFC.

    You have to use a /r to read or a /w to write. Thats what they mean in the usage.
