First off if your Linux distro is working with vPro, chances are you have a Kernal version 3.5 and up.
However in regards to FreeBSD, I have not heard of the drivers being included within the distro. You might be able to add the linux drivers, but for that you will need to ask a FreeBSD expert.
Here is some info from the Intel website:
Kamil, as for your second problem:
Intel had added new parameter (t) to those remote control form with hash related to time of session.
If you do not providing it, AMT will respond about session expiration.
I resolved it in two steps, first you should obtain page located at http://server:16992/remote.htm,
take value of variable t from this page and right after that submit your POST with curl but
adding this t value to POST parameters.
BTW in my case curl post was successful only if I use --data-urlencode instead of -d parameters.
Ok, I can leave curl... How on Linux (suported Redhat/SUSE) on/off/reset AMT from *COMMAND LINE* not web interface I want to do it massively on ~50 computers onetime. Is thre some sheel/perl/anything comman-tool in SDK or enywhere else ? Public domain amttool is not working stable. How I can reflash BIOS on ~50 computers? Do you have any tool?
