Are you saying the eGPU works without the primary video card working in Windows 8.x? Interesting. Worthwhile for you to 3dmark06 benchmark your video card which I presume is a NVidia one. If you get a score of < 10k then the x1 pci-e compression isn't engaging due to the iGPU not being functional. In which case you may wish to continue trying to get the DSDT override working to get the iGPU and eGPU allocated and working to gain faster eGPU performance, particularly with DX9 apps.

Indeed! It works!

I found a way that the eGPU works!

Boot into Setup 1.3, Menu Based

64bit address room for the iGPU

Force 32bit room to the eGPU

chainload windows and VOILA! The eGPU works. Now my iGPU has error 12 but who cares?

I'm gonna test it some further

Thx everyone, especially Tech Inferno Fan!

"pt MEM writefromfile 1 0xDAFE9000 dsdt.aml" 'works', but Windows won't start - only a BSoD...

Maybe the mistake is in my dsdt_....dsl File. Like described here: http://forum.techinferno.com/diy-e-gpu-projects/2109-diy-egpu-experiences-%5Bversion-2-0%5D-264.html#post82012

If I use your iasl.exe from that howto-package, my dsl compiles. If i use a newer iasl.exe Version from 2013 oder 2014 I get the error messages like in my post above. Is there a chance to fix this error? Or is there another opportunity to create an error-free dsl file that I can compile to this needed .aml file?

Edit: Even a non-edited dsl File won't compile... Same error.

OMG. I can't be so damn stupid Must be a hard week.. ;D I'll give it try...

Edit: @Tech Inferno Fan

The first five steps cant be executed in DOS mode. The 'pt MEM writefromfile ...' command was executed in the Setup DOS prompt.

@Tech Inferno Fan

It did it like 10 times now here are some Screenshots.

edit: sorry, i dont know how to make thumbnail views for the screenshots

edit2: now i used a newer version of iasl from this site: https://acpica.org/downloads/binary-tools

Now, it won't compile.

edit3: The line where the error shows up is (7160):

Boot Setup 1.30 -> DOS prompt, type 'pt MEM writefromfile 1 0xDAFE9000 dsdt.aml' to do the DSDT substitution, then type 'chainload mbr'. Confirm that you have a Large Memory area in your device manager. If this works

then that eliminates the DSDT substitution being the cause of the BSOD. Proceed then to add that line to your startup.bat, run 'setup', set PCI compaction->endpoint=56.25GB and then PCI compaction->Run compact, setting the scope to eGPU only, select Startup.bat->Test run then Chainloader->Test run.

Ok, then I'll pass on that. Maybe even help more information about the systems.

One is a Lenovo T530:

i7-3520M

HD4000, no dGPU

8GB RAM

Windows 8.1 64bit

I know that Lenovo shloud have no problems with TOLUD.

Hey guys, i'm the one with the T530 and TOLUD problems.

My latest try:

I used this howto (http://forum.techinferno.com/diy-e-gpu-projects/2109-diy-egpu-experiences-%5Bversion-2-0%5D-28.html#post31421). My TOLUD value is 0xFED40000 ~ 4GB.

My DSDT table starts at 0xDAFE9000. I installed Setup 1.3a. With 'iasl -g' I created the dsl file and edited it with the QWordMemory entry. 'iasl file.dsl' complied without errors and i got the dsdt.aml file. I rebooted into Setup 1.3 selected 'Start Setup 1.x with command prompt' and executed "pt MEM writefromfile 1 0xDAFE9000 dsdt.aml" - no errors. After that, with F10 I started the menu-based Setup and selected the "PCI 36-bit PCI compaction" on the eGPU and the "Force 32bit" on the iGPU. Till here it worked flawlessly. With a chainboot into Win8.1, I get a BSoD or my notebook just restarts.

Any further ideas? :/
