Just a reminder to anyone else tripping thru here that some manufacturers do reset such a setting on updating BIOS & otherwise @connor.blane forget about this portion. However, if you look thru the forum - search or someone else comes forward - I could have sworn that some others had had to turn IOMMU off to get their Qubes installation at first. Not like I have every forum post memorized so you should search while others consider it…for example one post that I just pulled up just to add an edit: Qubes 4.1 Not booting after bios update please help although this one might have a better take on it: I can only install Qubes OS without IOMMU but then it doesn't work correctly
