Small zip archive, 620 KB, for the MSI MS-6764 board. The file name contains only the brand and board code, leaving the document type, revision and version unspecified. Unpack it to see whether it holds a BIOS binary or a document. The MS code printed on the motherboard should match, as should the revision. Before flashing any image with a programmer, read and save the current chip contents and confirm the file size equals the flash chip capacity, since a mismatched image will not fit.
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.
