RAR archive of roughly 346 MB holding schematic documents filed under the heading Nvidia 2000, presumably related to graphics hardware of that generation. No specific model, board number or revision is given in the name, so the contents must be inspected to see which designs are included. Technicians use GPU schematics to follow core, memory and auxiliary voltage rails, identify power-stage components and find measurement points during short or no-power diagnosis. Match the PCB number and revision on the actual card or board before trusting any single diagram from the set.
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 @videocard_notebook_resistance. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
