BIOS dump for the Dell Inspiron 15 3531 on Compal motherboard LA-B481P, as stated in the name. Compal produces this board for Dell and uses its usual LA-xxxxP numbering. The 5.40 MB ZIP is intended for reprogramming the SPI flash with a hardware programmer to fix no-boot, no-display or bricked firmware faults. Before writing, check that the number on the PCB matches, read and save the existing chip to keep the service tag and system data, and make sure the image size equals the flash capacity.
