A check sum is a file that contains an information string.
On where the data block Start and End are of the file.
And what the overall file size it should be in Kb,Mb, of the file expected should be.

1.If the checksum is not found to verify its either the file is likely corrupted.
2.Not the correct file expected in correlation to what the Checksum states it should be in file size.

If you are doing a bios recovery and have downloaded the bios firmware file for the motherboard bios.
It means you are trying to flash the wrong type of bios file and the size differs from the bios flash bank chip used to store the new bios firmware. To the bios software file you are using to try update your bios.

It means you are trying to flash the wrong type of bios file and the size differs from the bios flash bank chip used to store the new bios firmware. To the bios software file you are using to try update your bios.

Go back and, check the exact brand name of the motherboard and it`s model number.
Company's who make motherboards often have the same model board with an extra suffix.

Example LE and Non LE model.
The bios files have to be different for each board.

So you must when searching for a new bios firmware ensure the exact model number of the motherboard is used to obtain the right bios firmware file for it including any extra suffix.

Get it wrong and you get the checksum error.

It is there to prevent you from flashing the wrong bios firmware to the wrong motherboard model number.
Meaning you are trying to flash the motherboard bios with the wrong file for the exact motherboard model you have.
