UNLOCKING Samsung R540 02KP BIOS

I need help,
I want to overclock my CPU of my Samsung R540 notebook.
I have also a good cooling for the notebook.. with 100% load of the cpu the temperature is at just 46°C.
So i want to overclock it ...
I' ve screwed the notebook up and i also couldn't find the PLL chip there near the crystal and anywhere. I also can't find the PLL ID of the IC because SiSandra can't find it.

The only way to overclock I can see is through the BIOS but the BIOS is locked so I need Your help to unlock it.

I hope you can help me to get this thing flashed.
