<!DOCTYPE html> <html> <head> <title></title> </head> <body><div>Hi Nicolas,<br></div> <div> </div> <div>Would you be able to send the full IOMMU groups tree for both NUCs? It's nice to see for the record. I was looking at using a Broadwell or Haswell one myself. <br></div> <div> </div> <div>Skylake was already out of real consideration for me as I was assuming there would be the same lack of isolation as your're noting. <br></div> <div> </div> <div>Slightly off topic ... I was leaning towards the Haswell NUC though since apparently only that IGD 4600 supports 3 external monitors via MST hub ... do you know anything about that vis-a-vis the Broadwell and Skylake NUCs?<br></div> <div> </div> <div>Seems like the NUCs are going backwards as the Intel packages go forward ... :(<br></div> <div> </div> <div>On Fri, Jan 22, 2016, at 07:26 AM, nicolas prochazka
