This is the most up-to-date BIOS available for the Shuttle (Spacewalker) AI61 motherboard. However, please note that this BIOS update MAY be considered BETA. Currently this BIOS update is NOT available from the manufacturers website. This IS the BIOS that is shipped with ALL current AI61 motherboards. Use at your own risk. I obtained this BIOS update DIRECTLY from Shuttle Techinical Support through direct correspondence.
