Another BIOS package for the LCFC board NM-E591 revision 1.0, carrying the JS47B and JS47C project codes and a 32 MB image size, but this archive is 8.95 MB, so its contents may differ from other uploads of the same board. LCFC is the Lenovo ODM behind NM- numbering. Extract and inspect the file, confirm it is exactly 32 MB to match a 256 Mbit chip, check the board marking, and back up the original SPI contents with your programmer before writing anything.
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.
