BIOS dump for the Dell Latitude E5530, built on the Compal board LA-7902P, supplied as a 5.46 MB RAR. Compal uses the LA-xxxxP numbering and builds many Latitude motherboards. Repairers program such an image to the SPI flash with a CH341A or similar tool when the laptop shows no post, a failed update or a corrupted firmware. Read and save the original chip first, because the Dell service tag and system data live in it, and check that the image size suits the chip.
