BIOS firmware for an MSI X17 notebook built on mainboard MS-17731, revision 1.2, packed as a 3.35 MB ZIP archive. MS-numbers like this follow MSI's own board numbering, with the last digit usually marking a board variant. The dump is meant for reprogramming the SPI BIOS chip with an external programmer such as a CH341A when the machine is bricked or fails to post. Read and save the original chip contents first. Confirm that the MS-17731 label and version on the PCB match, and that the image size equals the flash chip capacity.
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 @biosarchive. Enginerys does not host this file.
