[Request] Unlock "Advanced" and "Chipset" tabs on Samsung All-In-One DM500A2J

Hi I wish to unlock the first and second "Advanced" tabs and "Chipset" tab on Samsung All-In-One DM500A2J-K26L computer to see if I can get EXP GDC to work on mPCIe. I've extracted the rom with Afuwin, and I've tried to change Default to User/Supervisor, but that did not work. I've Googled this kind of Samsung BIOSes and there are not many results, but all first tries have failed but second succeeded.
