Archive for the Dell Latitude E5450 on the Compal LA-A901P board, revision r03, project code ZAM70, marked as tested and working. Compal board numbers follow the LA-xxxxP pattern, and here the Dell product is built on a Compal design. The contents are probably a BIOS dump for reflashing the SPI chip with a programmer. Check the LA-A901P marking and revision on the PCB first. Back up the original firmware before writing, since Dell images carry service tag and system data.
