BIOS dump for the Acer Aspire E1-531 laptop, board code Q5WV1 on the Compal LA-7912P motherboard with the Intel HM70 chipset. LA-xxxxP numbers mark Compal-made boards, which Acer uses widely. The RAR file, about 2.94 MB, is used for reflashing the SPI BIOS chip when the notebook powers on without picture or loops at startup. Check the LA number and revision printed on the PCB, back up the existing chip contents with a programmer, and make sure the image fits the flash capacity before writing.
