Hello Dudu, thanks for the reply.
I believe that you already knew, but a whitelist is fundamentally a list of hardware that are allowed by Bios.
Therefore, if the video card is not in the list, it will not be allowed.
I was able to detect it, with a lot of cost, using nando4 egpu setup, starting with the original wifi, and after booting the software, hotplug with EGPU.
If I try to start with egpu, black screen.
If I try hotplug without starting with wifi, it doesn't work.
Even, if I try to hotplug wifi, It can't be find.

If anyone can help me with this, I would be forever grateful.

you don't understand how it works...a whitelist in the BIOS exists for certain types of devices, namely wifi and wwan cards

Yes, and as far as I understand, if I understand correctly, by removing this list, I will be able to connect other devices, right?

That's what i want.

Hello, guys.
I need your help, I have LENOVO G400s with Intel Core i3. Currently, I changed the i3 to Intel Core i7 with Turbo Boost up to 3.2Ghz. It works well with base frequency 2.2Ghz, but I found that Turbo Boost frequency in my i7 is not active.
Can I activate Turbo Boost in my i7?

I uploaded my current bios, which was got by Universal BIOS Backup ToolKit 2.0

My Laptop Make: Lenovo
Model: G400s
BIOS Ver. : 7BCN21WW (v1.05)
EC Ver. : 7BEC21WW (v1.05)

Hi
Using the Universal BIOS Backup ToolKit 2.0 for your laptop model is not desirable...use BACKUP_Tools19 or fpt only
