Main BIOS image for the Dell Latitude E7440 built on Compal board LA-9591P, 8 MB in size. The name marks it as the main chip, separate from the EC/secondary image used on the same board, so each file must go to its own flash device. Compal laptop boards carry the LA-xxxxP code on the PCB, which should be checked first. Use an SPI programmer to back up the existing chip, then write and verify this dump to recover a board that will not boot or show a display.
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 @biosfilebins. Enginerys does not host this file.
