8 MB raw backup of the BIOS from Lenovo board NM-D151, an LCFC design used in the GV451 and GV551 laptops. Its size matches an 8MB SPI chip, so it can be written as-is with a CH341A or a similar programmer. Being a dump from a working unit, it contains another machine's serial and system data. Dump your own chip before writing over it. Compare the board number on the PCB, and consider the cleaned variant of this file if you need a fresh ME.
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 @schematiclaptopramkushwaha. Enginerys does not host this file.
