BIOS dump for the Acer Aspire One D150 netbook on the Compal board LA-4781P, delivered as a 722 KB RAR. Technicians use it to reflash the SPI chip with a programmer when the netbook powers on with no display or will not boot after corruption. LA-numbered boards are Compal designs, and the number is printed on the PCB. Confirm it matches, save the existing firmware before writing, and make sure the image size equals the flash chip capacity.
