Unlock CPU-Support Futro S450 / S500

Hello bios-mods.com-Team,

I have a Problem.
I changed the CPU in a Fujitsu Siemens Futro S450 to a Turion X2 TL-58 and in a S500 (nearly same Board) to a TL-60 for much more Power.

But both CPU only running with 800 MHz (like the normal CPU TF-20).
Is it possible to unlock the correct CPU-Speed by modifying the BIOS?

I uploaded the BIOS for you.
I'm really new at bios-modifying so please help me :-)

Thank you

EDIT: oops ... maybe its the wrong part in this Forum for my request? Please move if its wrong. Thx
