Repair archive in RAR format, 1.50 MB in size, associated with board code 4MPSV and the number 20, probably a revision. The name carries no other information, so the contents, whether a circuit diagram, boardview or BIOS image, must be confirmed after extraction with WinRAR or 7-Zip. A 4MPSV-11 package from the same code also exists, so read the revision on the board itself. Reference files like this help when following rails, checking signals and locating parts near a fault.
