BIOS image for a Lenovo laptop built on the LCFC board NM-E541, zipped to about 9.5 MB. LCFC, Lenovo's own ODM, uses the NM- prefix followed by a four-character code on its main boards, so the number on the PCB should be checked against NM-E541 before flashing. The name gives no detail on the BIOS version, chip size or ME state. Technicians usually program such a file onto the SPI flash with an external programmer when the board is dead or stuck after a failed update. Back up the existing chip first, since it holds serial and licensing data.
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 @vinafix_bios. Enginerys does not host this file.
