Raw 8.00 MB BIOS image in BIN format for Lenovo models listed as GS440 and GS540, motherboard NM-C511. The NM-xxxx numbering is used by LCFC, Lenovo's own design and manufacturing arm, on many IdeaPad and similar boards. An 8 MB image fits a 64 Mbit SPI flash chip and is normally programmed with a hardware programmer when the board will not POST. Read and save the existing contents before writing, because they may contain serial and system data. Check the NM-C511 marking on the PCB matches.
