Hi Paolo
I am not sure what do you mean - "You do not need a reset vector ...".
If so, where is the first instruction of the new CPU in the virtualization environment?
Please help me understand that at first. Then we can continue the discussion.
The BSP starts running from 0xFFFFFFF0. APs do not start running at all
and just sit waiting for an INIT-SIPI-SIPI sequence. Please see my
proposal in the reply to Laszlo.
