[VT-d] Intel i7-2600(sandybridge) and Intel DP67BG board

[VT-d] Intel i7-2600(sandybridge) and Intel DP67BG board

[조희승/Heeseung Jo]

I am working with Intel i7-2600 CPU on Intel DP67BG board and Xen 4.0.1
stable

Is there anybody to succeed in vt-d enabling? Or Any hints?
My xen log is below.

Hi,

you need the new BIOS after the 1900. The Beta BIOS is called 1950 but not 
aviable to the public. The releaseversion should come out in the next days 
acording to Intel.
