BIOS firmware package for the Lenovo ThinkPad T440s built on the VILT0 platform, board number NM-A051, supplied as a 6.86 MB zip archive. The NM-A prefix follows the LCFC numbering used for Lenovo-designed boards. Technicians use such a dump to recover a corrupted or password-locked BIOS by writing it to the SPI flash with a programmer such as a CH341A. Confirm the NM-A051 marking on your PCB, read and save the original chip contents first, and check the image size against the flash capacity before writing.
