BIOS for a Gigabyte 450M DS3H V2 desktop motherboard, revision 1.x, per the name. The 19.7 MB archive is larger than a typical single image, so it may contain an original vendor file plus a programmer-ready dump; extract and check sizes against the flash chip on the board. Technicians use these files to revive a board after a failed update via a hardware programmer. Back up the existing chip first and confirm the PCB revision is in the 1.x range.
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.
