Hi everyone, I have a MBP with Vista Boot Camp partition. Now, Parallels 3.0 will let you virtualize your boot camp partition, so I did just that. I opened my Vista partition in Parallels, and everything was smooth, until I saw that only 1 CPU was being used. I did some research and found out that Parallels does in fact limit the guest OS to one CPU while OSX uses the other CPU. No problem there, but now I've shutdown Vista and rebooted my mac and loaded up Vista via Boot Camp. You guessed it, only 1 CPU is being shown, and there is no option to display two CPU's. My guess is Parallels turned off some dual core functaionality switch and I have no control over. I sent an email to Parallels but not reply yet and that was almost 4 days ago, can anyone help?
