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. -- --------------------------------------------------------------------------- Prou top-posting : http://ca.wikipedia.org/wiki/Top-posting Stop top-posting : http://en.wikipedia.org/wiki/Posting_style O O O Gustau Pérez i Querol O O O Unitat de Gestió dels departaments O O O Matemàtica Aplicada IV i Enginyeria Telemàtica Universitat Politècnica de Catalunya Edifici C3 - Despatx S101-B UPC Campus Nord UPC C/ Jordi Girona, 1-3 08034 - Barcelona
