Lenovo BIOS dump for the NM-B241 board, 8 MB, with the Intel Management Engine region cleaned and marked as tested and working. The NM-xxxx numbering belongs to LCFC, the Lenovo owned board maker. A cleaned ME region is meant to avoid errors left from a used image, and the 8 MB size fits a 64 Mbit SPI flash chip. Write it with a hardware programmer after saving the original contents, since serial and system data may need to be transferred, and confirm the chip capacity first.
