Perhaps add "Docs must be more than screenshots or follow-the-monkey instructions". If it's not appropriate to explain what the system is doing, it is then appropriate to link to something that does explain it.

Docs that say/show anything like "Select Enable VTd to enable the VTd function" are useless docs. I won't bother providing a list of docs that do exactly that, but start by looking at your BIOS help!! I think we can assume that I understand "click" and "enable", but we should also assume that only the project engineers understand the acronyms and special functions. How about "The VTd function (Intel's Virtual Technology - Direct IO) permits virtual machines to do IO with fewer buffer transfers. Virtual machines may run faster, but could corrupt disk."
