Parallels Build 5582 Vista Ultimate Edition on Macbook Pro Leopard Parallels all of a sudden started giving me the error message "You are booting your guest operating system into PAE (Physical Address Extension) mode. Parallels Desktop does not support guest OS running in PAE mode. Please boot your guest OS in non-PAE mode to avoid this error." How do I boot Vista in non-PAE mode? It worked fine before and I didn't change anything.
