Acer Aspire V5-571P BIOS Unlocked hidden options

Hi, i want to change my dedicated vram, but.. u know it's limited.

Can anyone unlock the Bios?
Acer uploaded two different bios versions.

First: "BIOS - UEFI for Windows 8 (Not for Upgrades)" (v2.17)
I don't think this is the real Bios. There is a 13MB cap File in it.
Anyway, for completion:
original File (exe): https://www.dropbox.com/s/jugmprr7qybto1...17_A_A.zip
extracted and repacked (zip): https://www.dropbox.com/s/h791pxmm9uxwimn/VA410217.zip

Second: "BIOS" (v1.20)
This seems to be the real Bios, it contains a rom file. Edit: No, it's just an old version.
again the original: https://www.dropbox.com/s/j83f1dn9kribuh...20_A_A.zip
and the rom only: https://www.dropbox.com/s/5kq6rlszz17rj8n/VA41120.ROM

The title in the Bios is "Phoenix SecureCore Tiano".

Phoenix Bios Editor does not work. The PhoenixTool can extract a lot of things.. but i really don't know what to do then.

You would make me really happy.


Edit: Managed to figure out a module that could be the chosen one... thanks to Module-Helper (http://www.bios-mods.com/software-releas...e-helper/)

It's this module: OilSetupMainDxe from the v2.17 (https://www.dropbox.com/s/2i5uandngbq15i..._1951.ROM)

Edit 2: There is also a String like "OilHiddenPageConfig" in this file. Lets see... Maybe someone could help me there.

Edit 3: Let me crosslink this thread (Acer Aspire V5-531) as there should be a similar bios.
