Hi Gerald,
I found out via the discussion here: Fake Intel CPUs? - Super User
As far as I know Medion makes - let's call them - "budget" PCs. In Germany they are sold by Aldi (a discount grocery store chain) at a huge discount. I've seen a couple of them and they've pretty much always been feature-stripped down to the bare average-joe-minimum-requirements. If you own one of these PCs, I would be extremely surprised if they went through the trouble of adding vPro support to the BIOS. But, of course, I could be wrong.
Given how hard it is to find non-Intel motherboards that do actually support vPro, I would also not be surprised if there is actually a licensing fee by Intel associated with supporting it. But this is merely a guess. If this is the case, Medion would most definitely not support it on one of their budget-PCs and I doubt that there would be a BIOS update that changes that. Especially considering that there are other components involved in fully supporting it, like the LAN chipset, ...
So, you may have to upgrade your motherboard entirely. If you decide to do that, make sure that the ATX-connector of the power supply in the Medion case uses the standard pin-out. I've seen them deviate from that so that you have to buy their upgrades and that might fry your new board...
Good luck,
Markus
