BIOS archive simply named after the Lenovo G560 laptop, with no board number, revision or GPU variant indicated, so the contents should be checked after extraction. The 1.71 MB zip likely holds a raw SPI flash image meant for programming with an external programmer. G560 units were produced on different motherboards, so read the code on your PCB and compare it before writing. Always dump and keep the original firmware first and confirm the image size equals the capacity of the installed flash chip.
