Ben, thanks for that. Since reading your explanation, I have explored on Google and, though I`m not clear why, Intel has included this by default with little fanfare, for me at least.
I have had a look at the BIOS to disable it (just to stop the messages – I presume that would happen?), but cant see anything looking like it might be it that has an option to expand/modify its settings. Can you point me to where I might do this?
Perhaps of more importance, the Googling suggested that it offers remote access to the machine – hackers? Ive never seen any scare stories about such an activity, but because I dont know enough about it I am suspicious. Have you left it operational on your machine?
