Eh? On 9380 in front of me:
System Configuration -> Thunderbolt (TM) Adapter Configuration
There is a checkbox for "Enable Thunderbolt (and PCIe behind TBT) Pre-boot
modules". It's not checked by default, but that should turn on pre-boot ACL
stuff. That's the thing that Paul probably needs checked too.
But I mean this is generally an unsafe (but convenient) option, it means that you
throw out security pre-boot, and all someone needs to do is turn off your machine,
plug in a malicious device, turn it on and then they have malicious device all the way
into OS.
