Small zip archive, 603 KB, for the MSI MS-6595 board. The name offers no revision, chipset or document type, though a package this compact often holds a single BIOS image plus a flashing tool. Such images are written either from DOS utilities or with an external programmer clipped to the flash chip. The MS- code is MSI's own board identifier found on the PCB silkscreen. Verify it matches, read and keep the original firmware first, and make sure the image size equals the chip capacity.
