Sony VAIO VPCEE3WFX / PCG-61611L BIOS Unlock Request!!

[HerbRem]

I Am Currently Using a Sony VAIO VPCEE3WFX / PCG-61611L And I would like to Unlock Hidden Features and Advanced Options such as AHCI Settings etc,... Any help would be appreciated From what I understand it uses R0200Z5.ROM BIOS By default as that is what shows under Sony VAIO Care System Information as the Currently loaded BIOS however I have no Idea where to get the original bios .rom file as when I go to the support page it gives me an ISBSYS******* something or other .exe file to update the bios with I have tried extracting the contents of said file and does not seem to contain any normal BIOS files ie,.. .bin .rom etc,...  I really need to Unlock my BIOS Please Help me!! Someone....
