BIOS .zip 7.75 MB Shared

BIOS archive for the Lenovo ThinkPad L470, built on the DL470 board with code NM-B021, 7.75 MB packed as ZIP. NM-xxxx codes follow the LCFC numbering used by Lenovo's own ODM, and the code appears on the PCB silkscreen, so confirm it and any revision mark before flashing. The dump is meant to be written to the SPI flash with a programmer when the laptop will not boot. Read and save the existing chip first, keeping its serial and system data, and confirm the image matches the chip size.
