PDF schematic for the MSI MS-7A98 motherboard, with revision written as 22 in the name, most likely meaning revision 2.2. It is supplied in a RAR archive and opens in any PDF reader once extracted. The circuit diagrams help you follow power rails, the CPU VRM, the chipset supplies and the reset and power-good logic during diagnosis. Confirm the board revision on the PCB before relying on it, and use the MS-7A98 revision 2.2 boardview to find parts physically.
