Small backup archive for Lenovo-related LCFC board NM-A091 revision 1.0, named as an OK dump associated with an SMSC/Microchip MEC1633 embedded controller, so it is most likely EC firmware rather than a full BIOS. LCFC uses the NM- prefix for its boards. EC images like this help when a laptop shows no power, keyboard or battery charging faults; verify the controller and board revision and read the original chip first.
