Circuit diagram for the Biostar N68SC-M3S desktop motherboard, revision 6.1, supplied as a PDF in a RAR archive of roughly 1.41 MB. The index lists the brand as ECS, but the name itself says Biostar. A desktop schematic like this helps you check VRM phases, standby rails, the memory supply and front-panel or power-on circuitry when a board does not start. Unpack it and open it in any PDF reader. Compare the revision silkscreened on the board, because component placement and values can change between revisions.
