BIOS image for Lenovo board NM-C421 revision 1, numbered in the LCFC scheme used by Lenovo's in-house manufacturer. The 16 MB file is described as tested OK, indicating a working dump. Technicians write it to the SPI flash with a programmer such as RT809H or CH341A to revive boards that are dead after an update or show firmware corruption. Make sure the PCB carries NM-C421 revision 1, save the original contents of the chip before erasing, and check that the flash capacity is 16 MB.
