Firmware archive for a Lenovo board numbered NM-E901, delivered as a 6.45 MB 7z file. The name carries nothing beyond the board number, so the model, BIOS version and chip size must be checked after extraction. NM-prefixed numbers belong to LCFC, Lenovo's own design and manufacturing arm. Such dumps are flashed to the SPI BIOS chip with an external programmer to revive a board after a bad update or corruption; confirm the image size equals the flash capacity and save the original chip contents first.
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.
