Pytanie czy zdołała uratować te kaczki... Bo jak nie to dwie osoby zginęły na marne...

Ciekawe.. Komputery z procesorami Intela są kontrolowane przez***8230; Intela

Czytałem to niedawno i nawet miałem wrzucić tutaj gdzieś

How does this even work?
Without diving into the details or reverse engineering much of this, this is roughly how PAVP via the Intel ME works on Mac OS X. Applications such as iTunes and Safari are able to communicate directly to an IOKit service in the Intel Graphics drivers via an IOUserClient. They can negotiate and send in encrypted DRM blobs with keys to the Intel Graphics drivers. In turn, the graphics drivers are able to arbitrate communication with the PAVP application in the Intel Management Engine over the PCI bus, and deliver those encrypted keys and DRM content blob addresses. The Intel Management Engine then has some magic sauce (re: secret keys) that allows it to decrypt DRM keys and then decrypt the DRM blobs. Next, the Intel Management Engine writes directly to protected video memory to allow the Intel Graphics hardware to display to a computer monitor.

Pytanie czy w sterownikach pod linuksem jest to dostępne.
