ZIP archive of 256 KB labelled as an OROM firmware repository, meaning a set of option ROM images. Option ROMs are firmware modules for devices such as storage controllers, network adapters or graphics that a BIOS loads at boot, and they are often swapped or updated inside a BIOS image with editing tools. The name does not specify which devices or versions are included, so inspect the files first. Before inserting any module, confirm it matches the controller on the board and save a full copy of the original BIOS 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 @bioshub. Enginerys does not host this file.
