July 4, 20188 yr Hi, I have a Gigabyte GA-H81M-S2PV with a G3420 CPU which I would like to use as a pfsense vm, the CPU is vt-d capable and according to the system information IOMMU is disabled (which according to documentation means that it has the capability it is just not enabled? I have tried enabling ACS but nothing changes. I have been through every menu I can find on the bios (latest) but cannot find IOMMU anywhere but I need to pass through a 4Port nic, can anyone offer any advice? Many Thanks tower-diagnostics-20180704-0312.zip
July 4, 20188 yr In the manual it says you can enable Intel virtualization technology under bios features. If you enable it, vt-d might become available as an option also.
July 4, 20188 yr Author Hi @saarg Thanks for the info, Intel virtualization is enabled but vt-d is also enabled but greyed out so I cannot access it? so when looking at the bios everything is enabled.
July 4, 20188 yr Looking at Intels specifications site for you cpu, it says it does not support vt-d, only vt-x. So you can only use VMs without hardware pass through.

I saw the docs said disabled means capable and the bios said enabled (but greyed out) but also though vt-x would be enough to pass through... Have found some I7's that will sort the issue so maybe that's what I will do... many thanks @saarg I really appreciate your time!!
