Hi David,

There are some issues with the DMAR table which describes the VT-d
configuration to the host in the initial BIOS release for these systems.
I've been working with our BIOS developers to correct this and I'm
hopeful that next BIOS maintenance release will be more usable for
device passthrough.  Thanks,

Alex
