Schematic for the MSI B85M-G43 desktop motherboard, board MS-7823, revision 1.2, supplied in a RAR archive of about 1.2 MB. A technician uses it to trace VRM and standby power rails, follow the power-on sequence, locate the circuitry behind a short and check signals to the CPU, memory and chipset. The extracted document is usually a PDF that opens in any viewer. MSI uses the MS-xxxx pattern for its own boards, so check the revision on the PCB matches 1.2.
