Lenovo G50-70 firmware, machine type 20351, in a 3.19 MB RAR archive, with no board number or version given. G50-70 units shipped on more than one LCFC board, including NM-A271 and NM-A272, so identify yours from the PCB before relying on this dump. Use it to reflash a corrupted SPI BIOS chip with an external programmer. Check the image size against the chip capacity, and save the original contents before writing.
