Raw 8.00 MB BIOS binary for the Lenovo G50-80 on LCFC motherboard NM-A632. No revision or version is stated, so confirm the board number on the PCB before using it. The 8 MB size fits a 64 Mbit SPI flash and can be written straight away with a CH341A or a similar programmer. NM-A numbers follow the LCFC scheme used for Lenovo laptops. Read and save the original contents first, since they may hold the serial number and other machine-specific data.
