BIOS image for the Lenovo G40-30 notebook on board NM-A311, an LCFC board number, since Lenovo's ODM LCFC uses the NM-xxxx pattern. The 8 MB raw binary suits a 64 Mbit SPI chip and is meant to be written with an external programmer when the laptop does not boot or has corrupted firmware. Check that the board number printed on the PCB is NM-A311, read and keep the original chip contents first, and verify the chip capacity matches the image.
