Hello, I am setting up gpu pass-through for the first time and think I need some help.

The problem:
When booting my vm with a bios dump (acquired following these methods from Spaceinvader One: bios modification, general dump usage)

I came to the conclusion the vm does not boot because:

• The attached videocard (GeForce GTX 1070 Mini ITX OC 8G) does not output anything
• The MAC address of the VM never appears on my network.
•  

What I have tried:

• The same vm configuration, with a vnc graphic card (QXL)
• The same vm configuration, without the bios, with a vnc graphic card (QXL)
• The same vm configuration, without the bios

 

The same vm configuration, without the bios

• The attached videocard (GeForce GTX 1070 Mini ITX OC 8G) does not output anything
• The MAC address of the VM never appears on my network.
• Code 43 appears

I am attempting to install my nvidia driver via Gerforce Experience, in all the cases above that boot, I am getting Code 43 after reboot (in some cases before)

 

Threads and Videos I looked at before making this post:

I have also attached my modified rom dump for review.

Please let me know if I can provide any other details that will help, and don't hesitate to confirm I followed steps in any of the tutorials above because pebkac is a thing.

 

Thanks for your time,
