Official Lenovo BIOS for motherboard NM-A981, supplied as a 5.04 MB ZIP. The NM- board pattern comes from LCFC, the Lenovo-owned manufacturer, though the laptop model is not named. A vendor BIOS may come as an update package rather than a raw dump, so check whether it can be programmed directly or must be extracted first. Verify the board marking on the PCB, save the original chip contents, and match the image size to the flash chip before using a programmer.
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.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
