Lenovo firmware package for board NM-A981, containing BIOS and EC firmware according to the name. NM-xxxx numbers belong to LCFC, the Lenovo-owned ODM. Including the EC image is useful because the embedded controller handles power-on, charging and keyboard, and a corrupt EC can leave the laptop dead. Flash each image to the correct chip with a suitable programmer. Verify the board number on the PCB and back up both original chips before writing.
