RAR archive holding a PDF schematic for the MSI MS-7A40 motherboard at version 1.1, with the document reference 00017967 included in the name. MS-7xxx numbers are MSI's own desktop board codes, so the drawings come straight from the board maker. Technicians use such a schematic to trace VRM phases, standby rails, the SPI BIOS circuit and the power-on sequence when a board fails to start. Extract with WinRAR or 7-Zip, then check the revision silkscreened on the PCB matches 1.1 before following component values.
