Firmware package for the Lenovo ThinkPad E575, the AMD-based model, on board NM-A871, holding the BIOS and EC (embedded controller) images in a 3.73 MB RAR archive. NM-xxxx board numbers follow the LCFC pattern, Lenovo's own ODM, and are silkscreened on the motherboard, so match the number before flashing. Technicians use these images to revive boards with corrupted firmware or a dead EC. Always dump and keep the original chip contents with your programmer, and confirm the file size fits the target flash chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
