I have an HP Elitebook 8740w with a built in Nvidia Quadro 3800FX and 32GB of ram. I am trying to use Radeon R270X eGPU or an Nvidia GTX 580 eGPU. I would rather use the Radeon as an eGPU but I get an error 12 when used. The nVidia card works but disables the Quadro code 43. Attached is my dsdt file for my laptop. I was told to start deleting the offending lines and recompile but for each one I delete a new error pops up. I'm sure that it all means something but I don't know assembler and I am stuck on the instructions at the following compiler error. Any assistance from the community would be awesome and appreciated. Thank you.
