Firmware for the ASRock X99 Killer desktop motherboard, BIOS version 1.2. The 12.5 MB RAR archive likely contains a vendor update file rather than a raw programmer dump, so inspect its contents before flashing. A vendor file can normally be loaded through the board's built-in update tool. Writing it directly to the SPI chip with a programmer may need the file trimmed or converted first. Always back up the existing chip, and confirm the board model and that the file size matches the flash 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.
