BIOS dump for a Lenovo laptop built on the NM-B241 motherboard, an LCFC numbering pattern used for Lenovo designs. The name says the Management Engine region has been cleaned and the image was tested working. At 8 MB it matches a 64 Mbit SPI flash chip. Technicians write it with a programmer such as a CH341A when a board will not POST or the firmware is corrupted. Confirm the NM-B241 marking on the PCB, read and save the original chip contents first, then verify after writing.
