PDF schematics for the Gigabyte GA-EG31M-S2 motherboard, an Intel G31 based micro-ATX board with integrated graphics for LGA775 CPUs. No revision is stated in the name, so check which release the drawings cover before matching them to your PCB. Use the document to follow the CPU VRM phases, DDR2 and chipset power rails, video output and the power-on control path. It is useful for finding shorted components, missing standby voltages or the reason a board refuses to start.
