BIOS dump for the Lenovo G555 on Compal board LA-5972P, compressed into a 1.08 MB RAR. The LA number follows Compal's motherboard naming, so check the silkscreen on your PCB for the same code. The image is typically programmed onto the SPI flash with an external programmer to revive a unit that powers on but shows nothing. Read and keep the original chip contents before writing, and make sure the image size equals the chip capacity, otherwise the programmer will refuse it or the board will not boot.
