    I've a complaint from my bios boot about the checksum of the bios

    Prior to flashing it seems to say the checksum is E500 H
    Ohter bios tools(supplier) claim the bios is 63C1H ==> and marks it as a checksum error

    Did a simple mod I think fully successfull except for the Checksum and the
    boot complains

    I do not know if somehow I can alter the checksum ????
