Lenovo BIOS image in BIN form for LCFC motherboard NM-C821, marked as tested, 8.00 MB. The name gives no model name or revision, so match the board number on the PCB before use. LCFC, the Lenovo-owned manufacturer, uses NM- numbers for its laptop boards. The file size corresponds to a 64 Mbit SPI chip, and it is flashed with an external programmer to restore boards stuck without display or in boot loops. Save a full read of the existing chip first so original identity data can be restored.
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 @CLRINDORE. Enginerys does not host this file.
