Got it working!!! Only disabling the 635m did it Running at x1 2.0

I am trying to get my eGPU setup wroking before sharing my whole experience with the laptop I have: Asus N56vj I7 3630qm iGPU HD4000 dGPU nVidia 635m PE4L-PM060A v2.1b Windows 8.1 Pro TOLUD 3.25GB I am testing the setup with eGPU ATI 4890, planning to upgrade once I confirm that the setup will work I tested first with an external PCIe x1 wireless card. I tried to hotplug while the OS running, didn't work. Then rebooted with the card inserted and it worked perfectly. After that I can hotplug the card at anytime Then I moved to the HD4890 gpu. Hotplugged, nothing detected. Started the laptop with card inserted, the laptop restarted before showing Asus logo. Started again, took me to the BIOS by itself! Restarted again, system booted to windows fine! Device shown in the device manager as 'basic display driver' with error code 31. Installed ATI drivers, now the device name is correct ATI Radeon HD 4800, but with error code 37: "Windows cannot initialize the device driver for this hardware. (Code 37) Indicates two revision levels are incompatible." Any ideas? Would setup 1.3 fix this? Thank you
