Main BIOS dump for the Dell Latitude E7440 on Compal board LA-9591P, marked in the name as working. Only the main BIOS is referred to, so any separate EC firmware is not included. A dump like this is written to the SPI flash with a programmer when the laptop is dead, loops at startup or lost its firmware. LA-xxxxP numbers follow the Compal pattern; confirm the board number on the PCB, read and save the original chip first since service tag data is stored there, and check that the size fits the chip.
