Since publishing my rant a few days ago, I’ve discovered a few more motherboards which CLAIM to support VT-d (Intel Virtualization Technology for Directed-IO). Of course you need a non-K flavour of Sandy Bridge CPU as well (ie i5-2400, i5-2500, i7-2600).

So here’s the list so far, which I’ll update as I find more:

• Intel DP67BG (Confirmed, see comment by Michael)
• ASRock P67 (All of them, last time I checked – i.e. Pro, Fatal1ty) (Seems to be bogus according to Brian)
• ASRock H67M (And all variants)
• Foxconn H67S and variants
• Foxconn P67A
• ASUS P8H67-V and P8P67? (See below)
• BIOSTAR TP67XE and variants
• BIOSTAR TH67XE and variants

There’s a good chance that if one of the H67/P67 boards from the same manufacturer (i.e. ASRock and Foxconn) have VT-d, all variants have it too. You can check by searching VT-d in the product manual.

Update 6/02/2011 – Latest Asus P8P67 manual (E6307) shows the VT-d option under “System Agent Configuration”. Is this a new addition or something I missed before I’m not sure. Quick check of other Asus boards ie P8P67 EVO or P8H67-M indicates they don’t have it. Exception is P8H67-V which seemed to have it from the beginning. It seems there’s hope for those with Asus boards.

Update 24/03/2011 – None of the boards except for the Intel one seems to support VT-d even if they claim to. There are continuing claims that P67/H67 doesn’t support VT-d.
