BIOS archive for the Dell Latitude 7440 on Compal board LA-M591P, a RAR of about 10.8 MB. The LA-xxxxP pattern is Compal numbering, so Compal is the ODM behind this Latitude. The name does not state chip size, ME status or version, so inspect the extracted image before use. It is meant for reprogramming the SPI flash with a hardware programmer when a board will not post or is locked by a failed update. Back up the original chip contents first, keep the service tag data, and confirm the image size matches the flash chip.
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 @sbiosworldchannel. Enginerys does not host this file.
