  Use the checksum to correct the read, just like always. You don’t repair damaged ROM anyway.

    You can’t

    That’s not what a checksum is

      They probably mean EC code? That said, you can use checksums to “correct” errors if you have redundant copies of the data (by reading from the other copy if one copy has a bad checksum)
