Circuit schematic for the Gigabyte GA-78LMT-S2P desktop motherboard, with R40 in the name most likely indicating PCB revision 4.0. The PDF of around 800 KB lets a technician follow the CPU and memory VRM circuits, standby power, Super I/O and BIOS chip connections, and the front panel header wiring. Gigabyte often reuses a model name across several revisions with differing layouts, so read the revision on the board, usually near the PCI slots, before matching parts. Opens in any standard PDF viewer.
