Toshiba Satellite A660 BIOS unlocking

[Markospoko]

Hi

I would like to ask you kindly to unlock the above (my laptop's) bios if you can - i would like to be able to choose dedicated graphics card in optimus switchable (integrated + dedicated) configuration so the switching is off and the dedicated card is only used (if this is still going to send image to the screen). It would be useful if there were performance improving options available too.

Thank ya
