Hi

I suggest 2 searches within the DELL database....

The first to see if your device is listed as suitable, and the second "Attestation Failure" / "IOMMU" will list previous posts and potential solutions.

Please can you confirm the Make Model and OS, along with any configuration details like touch screen, backlit keyboard, SFF or tower etc etc.

Kind Regards
