Working BIOS dump for the Lenovo L340-15API on LCFC board NM-C101 revision 1.0, compressed as a 4.21 MB RAR file. The working label indicates the image was confirmed functional on a real board, which is useful when other dumps fail. NM-prefixed codes identify boards made by LCFC for Lenovo. Flash it to the SPI chip with a programmer to recover from corruption or failed updates. Match the board number printed on the PCB, confirm the image size fits the chip, and save the original contents first.
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 @afsbiosfree. Enginerys does not host this file.
