BIOS firmware archive for the Dell Latitude E5540, revision A00, covering both UMA (integrated graphics) and DIS (discrete graphics) board variants. The Management Engine region has been cleared, so the image can be written to a board without carrying over another machine's ME data. Pick the image that matches your graphics configuration and flash chip size. Before writing it with a programmer such as a CH341A, read and save the original SPI chip contents, because the service tag and other system data live in the stock dump.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
