BIOS image for the ASUS B450M-DRAGON desktop motherboard, an AM4 board on the AMD B450 chipset, supplied as an 8.18 MB RAR archive. The name gives no version number, so check the contents before use. A dump like this is used to recover a board that fails to post after an interrupted update, by writing the SPI chip with a programmer such as a CH341A. Save the original chip first so serial and MAC data can be restored, and ensure the image size matches the flash chip capacity before writing.
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.
