Thanks for replying!

I've tried everything you mention here with no success:

The BIOS is pretty basic, just allows to select boot order, set the 
date, and not much more than that. No sysctls also. I guess that my only 
option to check if the hardware has the feature will be to get windows 
on it and see what happens. If it works, then I will keep investigating 
further, if not, then maybe it is impossible to stop it (without using 
brute force, of course :-) )

Thanks for your help!
