Reposting in correct sub forum:
who is using the Thinkpad X1 Extreme Gen2 with an eGPU ?
I have it perfectly working fine with my Razor Core X but once I reboot the laptop or cold boot into the OS, it just hangs before BIOS POST (black screen, no beep). I tired
Disabled Kernel DMA protection
Disabled Thunderbolt security
Changed to Legacy boot mode
Update firmware of the X1 to 1.27
Using Nvidia 2080S or AMD Vega 64 Cards
Testing both TB3 ports
Does have someone similar experience ?
I can only POST with egpu unattached and then connect it during OS boot which is quite annoying.

Same Problem here. Looks like it is a whitelist in bios that prevent egpu from booting with POST... I hope lenovo could solve this problem. Sarcasticly, my old xps works fine with egpu. That's really not what I expect from a 2019 $2500+ laptop

eGPU is really a big topic.
I now always boot without having the eGPU plug in. After the thunderbolt software started running, perhaps 5 to 10 seconds after the logging in, then only I plugin.
