BIOS dump for the Lenovo ThinkPad Edge E440, board code AILE1 with number NM-A151 revision 1.0. NM- numbering belongs to LCFC, the Lenovo-owned manufacturing arm that produces these boards. Technicians write such an image to the SPI flash with a programmer to revive a laptop stuck on a black screen or failing after a bad update. Read and keep the original chip contents to preserve serial and system data, make sure the board revision matches, and check the image size against the flash capacity.
