Thunderbolt ssdt have arg1,2,3 errors when boot to os. If I boot it with eGPU it goes to kernel Panic. Can’t find kernel Panic log in console..I didn't know OPMFalcon was a valid FB, it doesn't show in AMD9500 Controller, same for ATY,Salado. Why those are working is a big mystery.
Whatevergreen may not be working to detect the eGPU if you plug it in after boot, but maybe it will work if it's plugged at startup.
Also use this Thunderbolt3 SSDT to fix your TB device tree and maybe that will also help.
(you may need to add DTGP at the bottom, as it currently references an external one)
The original and patched bios is here: https://www.techpowerup.com/forums/...mobile-moded-vbios-for-hp-zbook-15-g3.279373/My 4170 came with a blank ROM, so I spent a while trying to source a "vanilla" ROM and this is the best I could get.
Can you share your original VBIOS?
