Firmware image for a Lenovo ThinkPad Edge E531 built on the VILE2 platform, board NM-A044 revision 1.0, with U6 most likely marking the flash chip position on the PCB. The NM-xxxx numbering follows the LCFC (Lenovo) ODM pattern. The 4.00 MB raw binary suits a 32 Mbit SPI chip and is flashed with an external programmer to recover a dead or bricked board.
