I'd like some further info on VT-d as well. Most of the information on Intel's website is high level marketing speak. The only place I could find device specific information was this thread and the VT-d wiki on Xen's site. I looked at the Asus P5E-VM DO motherboard manual, and VT-d is specifically mentioned as a bios option. I would like to know if the upcoming P45 chipset will support VT-d as opposed to the Q45. Why doesn't Intel have a product matrix so that we can easily find chipsets that support VT-d? The authoritative source of this information shouldn't be coming from forum threads and wikis.
