Firmware archive labelled for a Dell 2205, packed as a 1.21 MB rar file. The name also carries the codes MP-00008288-004, C39-9.20 and E315671, which look like internal part, version and certification references printed on the board or its label, though their exact meaning is not stated. Before using it, compare these numbers with the stickers and markings on the actual unit, since mismatched firmware can leave the device unusable. Keep a backup of the existing chip contents and verify the dump size matches the target flash memory.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
