Lenovo BIOS image for board NM-D031 revision 1, a number from the LCFC scheme used by Lenovo's own board maker. The 16 MB file is labelled ok and builded, meaning it was assembled or rebuilt from parts and then reported as working. It is meant for writing directly to the SPI flash chip with a programmer to recover a board with corrupted firmware. Before relying on it, check the board number and revision on the PCB, back up the original chip, and note that the serial and system data may need restoring.
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 @generalbios. Enginerys does not host this file.
