whats left for me to try? thanks

Hello @cyberc883 and welcome to the NVIDIA developer forums.

I am sorry to hear that you have trouble getting your setup to work properly. Sadly I cannot immediately help with this topic and I am hard pressed to identify who might be able to. This could very well be a limitation of your motherboard BIOS with respect to PCIe virtualization.

Maybe if you can give a bit more details on your complete HW setup? What Host machine this is, what kind of GPUs, etc.
Also, since I think this was a double post, would you mind closing or deleting the other post you created:

It might be confusing otherwise.

Thanks!
