Firmware set for the Dell Latitude E5510, packed in a 2.18 MB RAR archive. According to the name it contains BIOS and EC images sized for a 4 MB and a 2 MB flash chip, plus a separate BIOS file. Read the markings on both SPI chips on the board to decide which image goes where. A file whose size differs from the chip capacity will not fit. Save a full backup of each original chip with your programmer before writing, because it holds board-specific data such as the service tag.
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.
