Archive for revision 10A of the MSI MS-6504 desktop motherboard, compressed as RAR at roughly 599 KB. The name only states the board and revision, so the exact contents are unconfirmed; a PDF schematic is the likely payload. Any RAR tool will extract it. A diagram like this lets you follow supply rails from the ATX connector, check the CPU regulator stages and locate parts tied to a dead short. Match the revision on the PCB to 10A first, since earlier or later boards may be wired differently.
