Look, I'm not trying to rock the boat here. I like Asus products. I almost exclusively use Asus boards only, but this Thunderbolt issue for Z170 boards has to be addressed. We paid good money for these parts, and it's in official Asus documentation that they work together, with proof that they work in older bios versions, so please, fix the later bios releases to include a FUNCTIONAL Thunderbolt bios module. It's broken right now.
