Lenovo BIOS image for the motherboard NM-A273, with the Intel Management Engine region cleared so the ME starts in a fresh state. It is a raw 8 MB binary, matching an 8 MB SPI flash chip. The NM-xxxx numbering follows the LCFC pattern, the Lenovo-owned ODM. A cleaned ME image is commonly used to fix boot loops, long power-on delays or ME errors after a board swap. Dump and keep the original chip first, since it holds serial and UUID data, and confirm the board number on the PCB matches before programming.
