Hi guys ! And welcome to another question...
I've read all this topic and all I could find elsewhere. I watched multiple time many of Spaceinvaderone's video and in a last resort I'm turning to the community for help.
So. I have : Ryzen7, X570, GT710 slot1, GTX780 slot2. My W10 vm runs fine with either of the two GPU passed through (for the GT710 I load the ROM I found (and trimmed) on TechPowerUp). For both card, I use the HDMI output.
After installing CATALINA thanks to @SpaceInvaderOne I have a running OSX. I could even passthrough my GTX 780 without any tweaks (well I thing I changed Product Model Number to 14.2).
But, passing through the GT 710 (with rom) which is my primary card gives me and endless bootloop.
So, is the problem coming from :
- the fact that the GT 710 is primary GPU (eventhough I load the bios and the same confi works fine in W10 vm) ?
- it can boot on the GT 710 but is CATALINA missing something that causes the boot to fail ?
- i have no idea what I'm doing and I even couldn't post my problem in the right thread...
I do not get it that it works with the 780 and not with the 710... I'm really thinking this is a slot1/slot2 problem... Please do not tell me to swap the GPU's...
