BIOS image of 16 MB with an uninformative name, linked in this index to the LCFC board NM-D474 used in Lenovo laptops. NM- numbers belong to LCFC, Lenovo's own ODM. The raw binary is meant for writing to the SPI flash chip with a programmer such as the CH341A or similar. Since the name gives no model or version, confirm the board number on the PCB, read and keep the original chip contents first, and check that the chip is 16 MB, because a mismatched image size will not fit.
