BIOS firmware for the Gigabyte GA-990FXA-UD5 desktop motherboard, specifically the rev. 3.0 board, delivered as a 2.82 MB RAR archive. Gigabyte often changes firmware between PCB revisions, so the revision silkscreened near the expansion slots must read 3.0 before this image is used. The file can serve for recovery of a corrupted BIOS chip with an SPI programmer or the board's own update tools. Keep a copy of the original chip contents and check that the image size suits the flash fitted.
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.
