    upon reading, and checking the bios rom, it checks the checksum byte(s) to see if it was read ok. yours has an error.
    reason : - flat cmos battery - it should read 3 V - so replace it
                 - enter the bios, save the changes and the error must be gone; or you have a bad chip

    It means your battery is dead.
    Change your CMOS battery. Its in your motherboard, you wont miss it. Its like a coin shaped battery.
