Schematic for MSI board MS-7817 at version 1.0, delivered as a PDF of about 936 KB. MSI prints such MS-7 codes and the revision on the PCB, so a quick look confirms whether this set fits the board on the bench. The drawing is handy for tracing the power-on sequence, checking CPU and DIMM voltage regulators, locating a shorted part on a rail and identifying the SPI BIOS chip for reprogramming. A second MS-7817 file with a -12 suffix is also catalogued. Opens in any PDF viewer.
