BIOS for the Lenovo E470C and ThinkPad E470, UC8 platform, LCFC board NM-A821 revision 1.0, distributed as a 4.72 MB RAR archive. The EBR token is not explained in the name. NM-prefixed numbers follow the LCFC scheme, Lenovo's own ODM. Use the image to recover a board with corrupted firmware by programming the SPI chip directly. Read and keep the original contents first, since ThinkPad dumps carry serial and system data, and check the board revision before flashing.
