Zipped firmware image with a generic name, linked in the index to the MSI board MS-15831. MSI uses its own MS-xxxxx numbering, with the sub-digit indicating the board revision, so check the PCB label matches. The archive is 7.46 MB and likely holds a BIOS dump for the SPI flash chip. Because the name tells nothing else, open it and check the image size against the chip capacity first. Read and save the original chip contents before writing any replacement image.
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 @skclappybios. Enginerys does not host this file.
