IOMMU Issues

[ArcticFox69]

I believe this would fall under a motherboard/cpu issue (cause of iommu), but I'm not really sure

I bought a HP Elite 6300sff tower with an i5-3470 in it, both of which (tower, and cpu) support Intel Vt-D, I have it enabled in the bios, yet Unraid refuses to say that it is enabled, i have tried so many things, including adding "iommu=1 iommu=pt" in syslinux.cfg to no avail

Can anyone help? If not, ill try and contact unraid support.

what does the boot log say? I think dmesg | grep IOMMU will tell you

Which, I know for a fact is not true, as I even have it enabled in the bios, and im using a supported vt-d cpu

Try using intel_iommu=on

I had to boot up a windows install, and use HP's BCU utility to set Vt-D, it works great now! thanks though
