PDF schematic for the MSI MS-7120 desktop mainboard, labelled 1B with the code 940117, which probably encodes the revision and a release date. MSI prints the MS-7xxx number and revision on the PCB, usually near the PCI slots, so confirm it before working from these pages. Technicians use such a diagram to follow standby and main power sequencing, check what sits on a shorted rail, and identify missing parts. It opens in any PDF reader and is searchable for net names where the text layer survived.
