Tested BIOS image for the Gigabyte GA-B450M DS3H desktop board, reported as working. No revision or BIOS version appears in the name. The RAR archive is 20.2 MB, so check its contents to find the image that matches your flash chip before programming. Use it to recover a board that will not POST after a failed update, by writing the SPI chip with an external programmer. Dump and keep the original chip first, and confirm the image size matches the chip 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.
