MSI model code MS-6736 is all the name of this 851 KB ZIP reveals. It may contain circuit diagrams, a BIOS image or other repair reference, which you should confirm after extraction. MSI uses MS- numbers as its in-house board designations and prints them on the PCB, so check that marking and the revision against the files. A schematic supports tracing supply rails and signals and finding test points. A firmware image should only be programmed after backing up the original chip.
