Tested BIOS image for the HP DV4 laptop built on Compal motherboard LA-4117P, sized for a 2 MB flash chip according to the file name. LA-numbered boards are Compal designs, and the number is printed on the PCB near the edge or under the memory area. The 960 KB RAR unpacks to the dump used to reflash the SPI chip with a programmer when the notebook powers on without display. Read and store the original contents first and verify that the chip is indeed 2 MB so the image fits exactly.
