Lenovo BIOS archive for motherboard NM-B242, supplied as a 5.11 MB ZIP, with no laptop model stated in the name. The NM- prefix is the board-numbering pattern of LCFC, Lenovo's own design and manufacturing arm. Technicians reflash this image to the SPI chip with an external programmer to restore a board after firmware corruption. Confirm NM-B242 on the PCB, as neighbouring numbers such as NM-B241 are different boards, back up the original chip, and check that the image length equals the flash size.
