Tested firmware archive for Lenovo board NM-E111, revision 1.0, project code JK4A0, designed by LCFC. The fairly large archive may hold several images or a full dump set, so review its contents before programming. LCFC names Lenovo mainboards with NM-xxxx codes, and the board marking must match. Use an SPI programmer to reflash a corrupted BIOS, keep a backup of the original chip, and verify that each image size matches its flash device.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
