just a question, I set Primary Display Selection to PEG and save and reboot. but after checking it again it reverts back to Auto. does this have to do with Nvidia Optimus feature on my laptop?

there is no undervolting and dGPU selection as the main one.

The manufacturer left some of the settings hidden, because a significant part of them does not work. He would have been obliged by regulators to continue the costly support if he hadn't hidden them and received complaints from users on many different platforms that they had broken their devices.

No, it doesn't. I'm sorry.

do you remember if there was a tabs unlock for Phoenix SCT somewhere made by your patch method in this thread?
I searched the net to see if this was a breakthrough, and if you please, I'm going to dig into modding of such bioses starting with the Acer 5560.

Yes on bios-mods.com i made using swap GUID method and there is also a modify made on Insyde with this metod ...

There are Samsung , Lenovo and Acer Phoenix SCT modified with swap :

Offset 0x0290h : Table Menu ID

778B1D826D24964E8E103467D56AB1BB Information
50D372ABB0822A4084C8164BB7DEB828 Configuration --> to 778B1D826D24964E8E103467D56AB1BA >> (Advanced)
EE1966EF7DF78C4A8693D60D6AA56702 Security ---------> to 778B1D826D24964E8E103467D56AB1BA >> (Advanced)

0D837A68FB555A419520182789353284 Exit

Here in example we can swap the GUIDs and without change nothing only the GUID we will get shown the FormSetID Advanced
so we swapped the Configuration or Security with Advanced.
Normaly into Lenovo there is the Date / Time GUID tab to use ...

But it's possible to intercept the routine where the choice is made and then we can force the endup ...

i'm heppy you agreed with me and i am sure you are friend of me not like others ;)
Let me know
Regards

( it's my sign >> let me know regards = BDMaster)

P.S. into Insyde we follow the Donowan6k scheme, but now from 5 version more is different and we can use it on Insyde too !
