BIOS firmware for LCFC motherboard NM-B911 revision 2.0, listed for the FE490, FE590 and FE480 projects and marked as tested OK, in a 6.45 MB RAR. LCFC is Lenovo's in-house ODM, and NM-xxxx codes appear on many IdeaPad and V-series boards. The image is meant for programming the SPI flash chip with a hardware programmer to revive a bricked or non-booting board. Save the original chip contents before writing, and check that the image size matches the installed flash chip.
