While dell has not gone into detail on this offering, from what has been
described it is highly likely that they were setting the HAP bit.
Unfortunately Dell has been billing this as a "inactive" ME when the
truth is something else: apparently the ME is still vulnerable even with
the HAP bit set , for instance.
In general there is a lot of confusion as to the ME and what me_cleaner
/ the HAP bit can do. To clear it up:
* Intel does not offer ME-free hardware to _anyone_, ever. The closest
they ever came was the HAP bit.
* A ME with me_cleaner applied and the HAP bit set is _not_ disabled.
It is limited compared to a stock ME but most definitely active and
involved with system boot and possibly runtime, and it remains a serious

Or in other words (I hope that I will avoid getting sued for this.. ;-)) : do you think that "buying" this advertised "option" is as reliable as say .. using open source tools like me_cleaner (DIY approach)?..
