I think you are wrong. Keep in mind that the biossums utility already
calculated the correct checksums for the DMI structure for the whole
SMBIOS structure and for the whole BIOS when the code was compiled.

Now we change some elements in the DMI structure and adapt the checksum
of this structure. Because the DMI checksum is part of the whole SMBIOS
structure, the overall SMBIOS checksum does not change (the new DMI
checksum neutralizes the change in the DMI table and neither the checksum
for the whole BIOS changes.

Kind regards,

Frank
