MSI MS-7A94 revision 1.0 circuit diagram, packed as a PDF in a 3.2 MB RAR archive. It covers the first release of this MSI desktop mainboard and is the reference for tracing the power-on sequence, CPU and memory supply rails, SIO and BIOS chip connections. Open the extracted PDF in any reader and search by net name or reference designator. A separate r2.0 schematic exists for this board number, so check the revision printed on the PCB, because later revisions may move or change parts and the pages will not match one to one.
