They come with Intel Boot Guard and you are won't be able to boot
anything which is unsigned and
not approved by OEM. This means the OEM are fusing SHA256 public key
hashes into the southbridge.
For more details take a look at Intel Boot Guard architecture. It could
be also confirmed by Secunet AG and Google.
That's scary to say the least. No more Thinkpads for us...
Is it used by Lenovo?
I think I can boot a USB-Linux on a new Thinkpad within a friendly Lenovo Store.
How can it tested? What registers must be read?
