BIOS and EC firmware for the Lenovo ThinkPad Edge E540 on board NM-A161, revision 1.0, with the Intel Management Engine region repaired. A fixed ME region helps avoid symptoms such as slow boot, fan running constantly or shutdowns caused by a corrupted ME. The 8.05 MB RAR holds the images for SPI programming. NM-xxxx numbers belong to LCFC, the Lenovo-owned ODM. Check the board number and revision on the PCB and back up the original chips before writing anything.
