Lenovo G580 BIOS archive of 2.74 MB, the name adding the number 20157, which is Lenovo's machine type for this model rather than a board number. Several motherboard designs exist for the G580, so locate the board code on the PCB and confirm it matches the image inside. The dump is intended for direct programming of the SPI flash when the laptop shows no image or loops on power. Read and store the original chip contents before erasing, and check that the image size equals the chip size.
