Firmware archive for the Gigabyte GA-990FXA-UD5 motherboard in its rev. 1.x hardware version, 1.07 MB in RAR form. Earlier revisions of this board use different firmware from later ones, so do not mix it with rev. 3.0 images. Check the revision marking printed on the PCB before flashing. A technician would extract the binary and write it to the BIOS chip with a programmer when the board shows no display or loops on boot. Save the original dump first, since it holds board-specific data such as the MAC address.
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.
