MSI schematics for mainboard MS-14B2 version 10, which also covers sub-board MS-14B21, as a 1.62 MB PDF. Version 10 is a later revision than 0A releases, so component values and nets may differ. Match the version silkscreened on your board. A technician uses these pages to trace power rails, find enable and power-good signals, read connector pinouts and locate parts near a short. Open it in any PDF reader and search net names to move between sheets.
