Here is another good link, albeit a little dated:

http://www.intel.com/technology/itj/2006/v10i3/2-io/7-conclusion.htm

The article is called "Intel Virtualization Technology for Directed I/O (VT-d): Enhancing Intel platforms for efficient virtualization of I/O devices".

Last year, intel created a page about "Direct I/O for Cloud Computing". All the video fully explain about Direct I/O. Where is the page?

the "Download PDF" link of

http://www.intel.com/content/www/us/en/architecture-and-technology/64-ia-32-architectures-software-developer-vol-1-2a-2b-3a-3b-manual.html

is broken "and could not be repaired."

can you arrange to have it repaired?

Just checked the link and it seems to work okay for me. Sorry you are having trouble.

Just checked the link and everything is good!
