Lenovo BIOS image of 16 MB for board NM-D474, the numbering style used by LCFC, Lenovo's own design house. The name states only the capacity, so confirm the model by checking the board number printed on the PCB. The file matches a 128 Mbit SPI flash and is meant for reprogramming with an external programmer when the laptop does not start or the firmware is corrupted. Save the original chip contents first so the serial number and other unit data are not lost.
