Claim 5:
6. The method of claim 5, wherein each of the plurality of controller hubs include a plurality of IO pins coupled to a set of handshake wires, further comprising:
sending a platform reset handshake signal from a first IO pin of the first controller hub to the platform control entity;
for each controller hub other than the first controller hub,
receiving a wake handshake signal from the platform control entity at a second IO pin;
booting or waking the controller hub; and
when the controller hub has successfully booted or has awaken, sending a wake acknowledgement (ACK) signal from a third IO pin on the controller hub to the platform control entity;

verifying, via the platform control entity, that a wake ACK signal has been received from each controller hub other than the first controller hub; and
triggering a reset for each of the plurality of CPUs.
