Archive for Lenovo LCFC board NM-A831, revision 2.0, associated with platform code CE570, compressed as a 3.19 MB RAR. The name does not specify whether it holds a schematic, boardview or firmware, so check the contents before use. LCFC, Lenovo's own design arm, uses NM-xxxx codes printed on the PCB with the revision, and they should match your board. Schematics guide rail and signal tracing, boardviews help locate parts and test points, and any dump should be flashed only after backing up the original chip.
