Lenovo BIOS binary for board NM-C121, 16 MB in size and therefore aimed at a 128 Mbit SPI flash chip. According to the name the image has OBRAM disabled, typically done to bypass failed soldered memory so the machine runs on its SO-DIMM slot. The NM- prefix is the LCFC numbering used on Lenovo boards. No test status is stated, so dump and keep the original firmware first, check that the flash chip size is 16 MB, and confirm the board marking before writing it.
