Schematic set for Foxconn M960 and M970 boards, H model, with the extra tag RSA, packed as a 953 KB RAR archive under the ECS brand entry. No revision is given in the name, so check the revision block on the title page against the PCB. Because one set covers two model numbers, expect option pages or stuffing notes that separate the variants. Technicians use such drawings to follow power rails from the input jack through the regulators, find test points and isolate shorts. The archive likely holds a PDF readable in any viewer.
