You need to Flash that BIOS and then make a backup BIOS. Then download AMIBCP and open the BIOS and see if there are any Options that are Hidden. I seriously doubt that there are any Options to be Unlocked. If you want to OC that PC, you need SetFSB or a similar app.
Thank u,i need the bios with PEG/PCI option for disable PCI and boot only PEG,any idea?it is a notebook sony vaio VGN FW51ZF/H
