BIOS dump for the Lenovo ThinkPad E460 built on the NM-A551 motherboard, with a date of 2015-07-28 included in the name, packed as a 4.82 MB RAR archive. The NM- prefix is the LCFC numbering pattern, the Lenovo-owned ODM that designs many ThinkPad and IdeaPad boards. Technicians use such a dump to reflash the SPI BIOS chip with a programmer after corruption or a failed update. Confirm the board number on the PCB, read and save the original chip contents first, and check the image size against the flash capacity.
