Please ask for support in the main DSDT Override or DIY eGPU Experiences Thread.
I have been out of the eGPU realm for too long to provide adequate support.
Here is a guide to performing a DSDT override with hopefully less misery, and setting up your computer to have your iGPU, dGPU, and eGPU working at the same time! Oh boy this is going to be fun.
This is my system specs (Fujitsu T901):
i7-2620M
16GB RAM
NVS 4200M
GTX 660 Ti
Windows 7 Enterprise x64
Now it begins..
Disconnect your eGPU until I say so.
If you can, you should perform a DSDT override. The method shown in the official thread was really hard at
How to perform a DSDT override:
Now for the fun part........
Disconnect your eGPU
Uninstall ALL (ALL MEANS ALL) (dGPU included!!!) Nvidia drivers (keep the Intel graphics driver)
Use Driver Sweeper and check all the Nvidia options, run, reboot, turn off computer -- don't install the driver for the dGPU yet
Connect eGPU and go to Setup 1.x
Set your eGPU port to G2 (assuming your have an adapter that supports G2, and your computer as well - if not, then skip setting the port to G2)
dGPU off
32-bitA compaction for iGPU eGPU
chainload to your OS
Windows may yell at you to reboot due to hardware changes, don't quite yet
Check device manager, you might (I did) have error 43
Attempt to install the latest Nvidia drivers for you eGPU -- still don't install drivers for your dGPU
If your lucky, it will install, if not:
shutdown/reboot
Setup 1.x
do the same as before (dGPU off and such)
Attempt to install the Nvidia drivers again for your eGPU
After a few hours of fiddling around, you should get them installed
(keep your dGPU off this whole time)
ONLY AFTER YOU GET YOUR eGPU DRIVERS INSTALLED!!
(and as such, error 12 in device manager)
Go to Setup 1.x
Set port G2 on your eGPU port (again, if you support G2)
32-bitA compaction for iGPU dGPU eGPU (or choose 36-bit if you performed a DSDT override)
chainload
You will probably get the reboot due to new devices again, but before you do, check device manager
Might have a generic VGA device or something instead of the NVS 4200M
Attempt to install the drivers for you dGPU now
If no luck, reboot and do the same Setup 1.x as before (with dGPU on)
Attempt to install dGPU drivers again
Reboot after you get your dGPU drivers installed
Keep the same Setup 1.x method
If your lucky you should have your iGPU dGPU and eGPU show up fine in device manager.
You can go to the Nvidia control panel and dedicate your dGPU as your PhysX processor, it works really well. (If you play stuff that supports PhysX and have an at least somewhat useful dGPU)
------------------------------------
I hope this helps.
^ over 20 hrs of fiddling around well spent ;-;
------------------------------------
HOW TO: Update drivers (probably):
Note:
You can check your driver version for both your eGPU and dGPU in the System Information dialogue box under 'Help' in the NVIDIA Control Panel (you can even check your Bus here too (PCI Express x1 Gen2 as shown for my eGPU).
Results:::::
iGPU + dGPU + eGPU
dGPU PhysX dedicated:
WEI:
ALL THE MONITORS (and all different resolutions too ):
Weeee~~~~~~~~~~~~~~
