I'm new to the forum, but have been reading through the extensive guides, FAQs, etc. over the last few days. I have a Bplus Pe4c v.2.1 Expresscard and hooking it up to an HP ProBook 6460B (detailed specs below). My purpose for going the eGPU route is that this is a work-issued computer, but the basic onboard Intel HD graphics driver won't display optimal resolution (1440p) on my monitor (no gaming; just need more real estate on screen for multi-tasking). Anyways, laptop recognizes graphics card (simple Zotac Geforce GT 640 2gb), have loaded Nvidia drivers, but get the dreaded Code 12 issue. I started to follow the detailed guide provided here, but get stuck on Step 3 (Decompile dsdt.dat to get an output dsdt.dsl text file), as I'm getting a warning about unresolved control methods. I've included part of the actual DSL file with the beginning of the warnings below. I'm hopeful someone can assist me in getting through this step or suggest another option.
