BIOS together with EC firmware for the Dell Latitude E6540, packed in a 10.7 MB RAR archive for the Compal LA-9411P motherboard, with VALA0 being the board code name shown in the file name. Having both the main system BIOS and the embedded controller image in one set is useful when a board stays dead or shows no power-on activity. Compal uses the LA-xxxxP numbering, so confirm it on the PCB silkscreen first. Read and save the original SPI chip contents with a programmer before writing anything, and check that each image size matches its flash chip.
