Yeah, it worked with Vista, when I first bought and booted it, before I |
34 |
nuked it off my system. It should be implemented in the hardware but to |
35 |
save a few gates it is not done. They leave it up to software engineers, |
36 |
which is alright when you publicly provide the documentation on how to |
37 |
do it. |
