PDF circuit diagram for the MS-BA01 board at revision 3.1; the file name states no brand or model beyond this code. A newer 4.1 revision exists, so read the revision marking on the PCB and use whichever document matches, because parts and nets may change between versions. Typical uses include checking which regulator creates a missing rail, tracing enable and power-good signals, and locating components around a short to ground.
