Duplicate copy of a Latitude E7440 BIOS package for the Compal-built LA-9591P REV1.0 board, again marked for a single 8 MB flash chip. It matches the size of the similarly named file and is likely identical, so compare checksums before choosing one. The dump is written to a 64 Mbit SPI device with a CH341A or similar tool. Back up the chip first, because it holds the service tag and ME data, and confirm the board revision.
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 @SCHEMATICWORLD. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
