Raw 32MB BIOS image for the LCFC board NM-C661, used in Lenovo laptops. The name gives only the board number, with no model, revision or CPU variant; another dump of the same board is tagged for 10th-gen CPUs and revision 1.0. LCFC is Lenovo's ODM and uses NM-xxxx codes. Before flashing with an SPI programmer, back up the original chip, which holds serial and system data, confirm the board code on the PCB, and make sure the chip is 32MB.
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.
