A wrong or corrupted file will trigger the error message we discussed earlier. When you download a BIOS, check its size. It should be 2,097,152 bytes (exactly 2 MB) . You can also use a hash checking tool to compare it against the known good SHA1 checksum: 8951d1bb219ab2ff8583033d2119c899cc81f18c . If the checksum matches, the file is 100% correct. This guide provides the safe, professional roadmap to
