BIOS dump for the Lenovo ThinkPad E540 on motherboard NM-A161, packed in a 4.77 MB RAR. NM- numbers follow the LCFC naming pattern used for Lenovo boards, so the code printed on your PCB should read NM-A161 before you use this image. The usual job is reprogramming the SPI flash with an external programmer to recover a board that will not boot or show an image after a failed update. Back up the existing chip first to keep the serial number and system data, and verify the image size against the flash capacity.
