MSI MS-V388 material for revision 1.1, held in a 2.08 MB RAR archive. The MS-Vxxx numbering belongs to MSI and usually identifies its graphics card PCBs. What the archive contains is not stated, so extract it with WinRAR or 7-Zip to check for a schematic, boardview or firmware dump. Since later revisions of the same board also exist, confirm that the PCB is marked revision 1.1 before tracing circuits, and back up any chip before writing an image to it.
