Circuit schematic for the Biostar A78GA-M2T desktop board, revision 6.4, delivered in a 664 KB RAR file. It is the reference for checking the CPU VRM, memory supply, chipset rails and front-panel power button path when a board will not start. The PDF can be read with any document viewer, and searching by net name speeds up tracing. Revision 6.4 must match the marking on the PCB; earlier or later revisions may use different parts or routing.
