BIOS image packed in a RAR archive for the Gigabyte B450M K desktop motherboard, revision 2.0, marked by its source as tested and working. Use it to recover a board with a corrupted or failed SPI flash by writing the extracted image with a programmer such as a CH341A. Before flashing, confirm the PCB silkscreen shows rev 2.0, read and save the original chip contents as a backup, and check that the image size matches the capacity of the installed flash chip, since a mismatched file will not fit.
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 @biosdumpcomputer. Enginerys does not host this file.
