How to check AGP bus speeds?

Looking to see if this board has locks, just got it today from NewEgg. I'm at 204 FSB, so I'd like to see if all is well. Oh yeah where can I get the beta bios that enables locks?

ASUS A8V Deluxe

use this program to control/read bus speeds. Goheels had a link to the 1005.021 bios that enables locks on boards with higher serial numbers
