Archive of roughly 4.19 MB for the MSI MS-7024 motherboard, compressed with RAR. The name states no revision or file type. A separate MS-7024 rev 1.4 boardview exists in this index, which may help alongside these files. Open the package to see whether it holds schematics, firmware or both. Technicians use such files to follow power rails, check for shorts and locate parts. MS-7xxx is MSI's own numbering. Check the PCB revision before relying on the files, and back up the BIOS before reflashing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @IT_SERVICE_WORLD. Enginerys does not host this file.
