I tried all delay settings. TOLUD is C0000000 so looks good there? Reduced ram to 4GB. Still only iGPU is detected. I'm guessing I have faulty equipment at this point. Maybe a bad HDMI / Expresscard? My original post:

I have a HP Elitebook 8440p, core i7, 8GB Ram that I'm trying to set up with an eGPU. 430W Power Supply > Old GeForce 8800 GS (for testing)> PEH4 to Expresscard. I have three green lights on my PEH4, fan is spinning on the video card. It's not showing up on my system at all. I hear talk about an "error 12" but I haven't seen it. Is my video card too old? Is my equipment possibly faulty? Do I need to do a DSDT override? Thank you!
