Hi! how can I verify the non-execution of option roms? I recently 
noticed that I had somehow turned that on with one of my latest compiles 
(without yabel secure mode either)

The idea is that a hostile firmware update could flash a PCI-e card 
assigned to a VM and then mess with the host after the PC is rebooted 
(can be solved by using SR-IOV devices, but KGPE-D16/KCMA-D8 lacks 
SR-IOV support in coreboot despite the chipset supporting ARI)

I realize that I am a nobody and this is very unlikely to happen but OFC 
I still want max security >:3
