Schematic for MSI board MS-7800 revision 1.0 in PDF format, compressed into an 884 KB RAR file. MSI identifies its boards with MS-numbers printed on the PCB, which is how to confirm this document applies. The diagram supports tracing power rails, locating the circuits behind a short and checking signal paths between the chipset, CPU and peripherals. Open the extracted PDF with any viewer. Revision differences can change parts, so match the silkscreen revision against 1.0 first.
