Could you specify your question a bit? It’s a bit vague in general?
(What’s the meaning of life?)
- What motherboard model?
- What Thunderbolt controller generation/revision?
- Thunderbolt controller NVM firmware version?
Paging @Wendell for a clean-up at isle 3, I don’t know anything about the technical BIOS/UEFI initialization stuff except the security-settings sub menu, but that’s probably too high-level.
