Hi Guys,
I'm new to this community so hello to all of you. Just got my first eGPU - the BizonBox 3. On MacOS everything works perfect. But my Bootcamp Win 10 setup won't let me us it.
I get the Code 12 Error everytime i try to install it. I tried to disable and re-enable the PCI Bridges, but this does not seem to work.
No I want to try the DSDS override Method. But the terminal (executed as prompted admin) won't let me us "cd c:/ials" or whatever i need do that (the first command in the Guide in this forum). It tells me access denied.
Any suggestions? Thanks
Kind regards Julian

Welcome aboard.
The instructions at https://egpu.io/forums/pc-setup/fix-dsdt-override-to-correct-error-12/#post-716 require use of Command Prompt (run as administrator) to work.

@roqpir how's installation process of your BizonBox 3? I was not aware it's already in customers' hands. We'd love to see photos of your BizonBox 3 eGPU.

@nando4 Thank you so much! Everything is working now thanks to this guide. Is there any way to disable my testmode without losing the function of the eGPU? I can't install Optimus and I don't have any idea on how to get it working. Advise? Sorry for aksing repeatedly
@itsage Installation on MacOS went fast and without problems so far. I can clearly see improvements in gaming and 3D modeling Software. But installation with Windows 10 (Bootcamp) is quite a mess. It takes time to understand what you have to do, especially if you haven't done something like this before.
I have a MacbookPro 13" late 2016 W/TB i7 and I'm running a GT 980 Ti for those who are asking
@roqpir, did you see my copyright notice during the macOS installation? Is there Automate-eGPU folder in /Library/Application\ Support/ or automate-eGPU.sh in /usr/local/bin?

Nice one there.
To avoid using test signing mode you'd need a pre-boot DSDT injection mechanism to overwrite the in-memory version. That's possible with eGPU Setup 1.31 software if using MBR partitions. Your system uses GPT so would need to be done via say Clover bootloader. This looks like the easiest guide on how to do that: https://www.tonymacx86.com/threads/dsdt-with-clover.188393/

@roqpir Can you post more photos of your BizonBox 3? How many Thunderbolt 3 ports are in the back of this enclosure?
I'm not aware of any eGPU setup with AMD card works in macOS through Thunderbolt 3. If you have a Radeon GPU, we'd like to know whether it works on this BizonBox 3. Thank you!

@goalque, Sorry i did not see your copyright notice or anything else. Probably because i wasn't especially looking for that. I'm gonna check that out and tell you later where the automate-eGPU folder is located. I'm not at home right now.
Sorry guys, I was a little bit busy through the holidays. Happy New Year to everyone!
Here are some more photos of my BizonBox 3.

I'm going to open the Box to show you how it is looking from the inside. I will upload this pictures at the evening.
The case is very nice indeed!
