I recently build one homeserver with Proxmox 9.0.3 and having issue working UHD 770 for 13600k in Windows 10/11. It works perfectly on Ubuntu 22.04 desktop but driver shows 43 error in Windows.

I have other amd and nvidia GPUs that works perfectly with windows. The only issue is with igpu in windows.

I don't have plan to use any external rom if it is not from reliable source. can we do anything about it and work for native support or team release a rom to use?

[SOLVED] Thread 'IGD passtrhough working - Intel UHD 770'

I can even stop/start the VM several times and nothing explodes (So far).

What I wanted: I wanted one of my proxmox VMs to be a Windows 11 vm, with full...

Build your own ROM, the source code is already available, written by Intel and Red Hat engineers: https://github.com/LongQT-sea/intel-igpu-passthru?#credits--acknowledgments

The IntelGopDriver.efi file can be extracted from your motherboard’s BIOS using UBU
