Lenovo BIOS dump in a 9.79 MB RAR archive, labelled with the code HYG60HX4B0 and board number NM-D341, the second copy of a pair with the same name. NM-prefixed numbers follow the LCFC numbering used on Lenovo laptop boards. The name says nothing about ME state or version, so examine the contents before flashing. Match the board number on the PCB, back up the existing SPI chip with a programmer such as a CH341A, and compare the image size to the chip before writing.
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 @biosfilebins. Enginerys does not host this file.
