Lenovo BIOS for the LCFC NM-C781 mainboard, a 16 MB raw binary marked OK, meaning it was reported to work. The name says onboard RAM is disabled, so the image forces the system to run on the socketed module only, a common workaround when soldered memory has failed. NM-prefixed numbers follow the LCFC scheme used by Lenovo. Flash it with an SPI programmer after reading and keeping the original. Make sure a working module is installed and that the chip capacity matches the 16 MB image.
