Clevo 6-71-NL4xx boards

4 boards in the Clevo 6-71-NL4xx group with 6 BIOS files, 3 schematics and 1 EC firmware image. Brands: Clevo and Acer. Boards in one group share the ODM's numbering block; neighbouring numbers are often related designs, so their schematics are useful for comparison, but they are not interchangeable.
