Alienware 17 R1 egpu

[Blauber70]

I have the following problem:

I want to use an egpu with my old alienware 17 r1. (using mPCIe)

I build everything together but when I try to boot up I just get a black screen, I can't even open the bios. so I tryed to hotplug it but that didn't help either.

Because a lot of other users used the Setup 1.35 I bought that. But I still can't use it. Some said in other forums that you have to change the: "Bios-Primary display-IGFX or PCI"

But I don´t find this option in my BIOS.

Does anyone know what to do?

These options only become available when you have an unlocked BIOS, which you don't seem to have.
