BIOS archive for the Lenovo ThinkPad E570 with LCFC motherboard NM-A831, revision 3.0. The name does not say whether it is a full SPI dump or contains EC firmware, so check the contents after extracting. LCFC is Lenovo's in-house ODM and uses the NM- prefix for its board numbers. Technicians flash such an image with an external programmer to fix boards that stay dead after a bad update. Match both board number and revision to the PCB, save a backup of the existing chip, and check the image against the flash size.
