PDF schematic for the Gigabyte GA-Q77M-D2H motherboard, with R101 in the name, which most likely means revision 1.01, packed in a compact RAR archive. Circuit diagrams of a desktop board help a technician trace VRM phases, standby rails and power-on signals, and check component values around the chipset and memory slots. Any PDF reader opens it once extracted. Make sure the revision silkscreened on the PCB matches, since layouts and part values can change between board revisions.
