Nope if your bios dose not support it there is high chance that it will not work with the board. You can try it it won't damage anything. Toms tried with few that didn't clame that it supported Phenom but they still worked. But you handicaping your CPU
woah woah, thats not true. It is 100% likely that if your board doesn't have the proper power management to support a 125 watt cpu it will burn out your mobo, cpu, or both. I believe the guys here did an article on the amd 780 chipset and they burned through a few board before they realize the problem.
