BIOS image for a Lenovo laptop motherboard designed by LCFC under board number NM-B441, packed in a 7z archive of about 4 MB. The name does not give the laptop model, revision or chip size, so confirm the board marking and the flash chip capacity before use. NM-prefixed numbers follow the LCFC (Lenovo Compal) scheme. An SPI programmer writes such a dump to recover boards with corrupted firmware; back up the original chip first, since it may hold serial and Windows key data.
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 @efibios. Enginerys does not host this file.
