PDF schematic for board MS-N0141, revision 0A, with a PASS ERC note in the name, which typically indicates the design passed an electrical rules check. The MS- prefix resembles MSI numbering, though the input gives no brand, so treat that as unconfirmed. The drawing is useful for tracing power rails, finding the controllers that create each voltage and locating parts near a suspected short.
