Archive for board DAGC9EM8E0, revision E, in an 86.5 KB ZIP. The DA prefix and trailing revision letter resemble Quanta numbering, though here M8 replaces the usual MB, which may point to a sub-board or variant; the name does not explain it. The small size suggests a boardview or firmware file. Verify the code against the PCB silkscreen, and if the content is a dump, read and save the original chip before writing anything with a programmer.
