Lenovo BIOS for the LCFC-designed motherboard NM-E341, revision 1.0, provided as a 13.6 MB RAR archive and described as working. LCFC is Lenovo's in-house ODM, which uses NM-series board numbers, and the laptop model is not stated. Extract the image and check that it matches the SPI flash size before programming. It suits recovery of no-boot or black-screen units with corrupted firmware. Confirm the NM-E341 marking on the board, and dump the original chip first in case serial data must be restored.
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.
