Lenovo BIOS image for board NM-A273 with the Intel ME region cleaned, a raw .bin file of 8.00 MB. NM- numbering is used by LCFC, Lenovo's own laptop ODM, and is printed on the motherboard itself. The 8 MB size fits a 64 Mbit SPI flash chip, and the cleaned ME region helps recover boards that hang or fail to start because of corrupted Management Engine data. Flash it with an external programmer after dumping and saving the original chip, and confirm the NM number on the PCB matches.
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.
