Firmware dump for the Lenovo ThinkPad T440 motherboard NM-A102, packed in a RAR archive of about 3.83 MB. NM-series numbers belong to LCFC, the Lenovo-owned ODM behind many ThinkPad boards. A dump like this is typically flashed onto the SPI BIOS chip with an external programmer to revive a board that no longer posts or has a damaged firmware region. Make sure the board number printed on the PCB matches, keep a backup of the original read, and verify the image length equals the chip capacity before programming.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
