Archive for the MSI MS-7459 motherboard version 1.0, 1.40 MB in rar format. MS-xxxx is MSI's own board numbering, and the version printed on the PCB should match 1.0 before using the contents. The name does not reveal what is inside, so it may hold a BIOS dump, a schematic or other service data and should be checked after extraction. If it is a firmware image, use a programmer to rewrite the SPI chip, saving the original first and confirming the size fits.
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 @schematicslaptop. Enginerys does not host this file.
