Thank you all.
The box has already the last vendor's BIOS version.
I've checked the bios of another DELL machine (a laptop) having vt-d
on the micro, and the BIOS on that machine has an option to enable or
disable VT-d, while the bios of the DEL 3020 misses that option. So as
Konstantin said, the bios is not advertising the VT-d capability bundled
in the chip, so I guess I can't move until the vendor decides to
implement that in its bios firmware.
Best all and thank you,
G.
