Hi everyone,
I updated ProxMox to version 9.1.2 today.
I was wondering if there was still a solution for my HD530 iGPU in my Intel Core i7 6700T CPU, which worked great up to ProxMox 8.x.x.
I've seen some solutions for N100 and N150 processors, but there's nothing for my case yet.
I don't know where to find a ROM for the HD530 iGPU.
Should I just give up?
Thanks in advance to anyone who replies!

Hi,
I tried the procedure you suggested and... IT WORKS!
I'll explain in detail what I did and the hardware I have so I can perhaps help someone else:

1 - ProxMox 9.1.2
2 - Hardware: HP EliteDesk 800 G2 Mini
3 - CPU SkyLake Intel core i7 6700 and 6700T ( i've 3 nodes mix )

I initially tried the file: SKL_CML_GOPv9_igd.rom ( for Skylake to Comet Lake (6/7/8/9/10th gen) ) but unfortunately it didn't work, the VM with Windows 11 started but I had 100% memory and 25% CPU but it never finished loading the VM completely until the end.
I then tried Universal_noGOP_igd.rom and IT WORKS!!!!!
The only doubt I had was about point 2 of the guide, that is, the choice between LEGACY MODE and UPT MODE, I chose the first and I did this:
qm set [VMID] --machine pc \
--vga none \
--bios ovmf \
--hostpci0 0000:00:02.0,legacy-igd=1,romfile=igd.rom

But is this a choice I have to make? In other words, how do I want to set up the VM?

By the way, in my Win11 VM I had already set BIOS OVMF (UEFI) but as a machine I still have i440fx and not Q35
The fact is, everything is working fine now, and finally the infamous error 43 is GONE in the Win11 VM!
FANTASTIC!

YOU CHANGED MY DAY!

Do you think it's okay now, or should I try modifying something to use the first ROM that didn't work, because that might be the best one to use... or should I just leave it as is?

Thanks again, and if you have any questions, I'm here to help!
