Combined BIOS and embedded controller firmware for the AMD-based Lenovo ThinkPad E575, motherboard NM-A871, delivered in a 3.72 MB RAR archive. Including the EC image helps when keyboard, charging, fan or power-button behaviour points to EC corruption rather than the main BIOS alone. NM-A boards are LCFC designs, Lenovo's in-house ODM. Check the board number on the PCB, read and save both original chips with a programmer, and make sure each image matches its target chip size before writing.
