What is the green "Initializing" message at the top of the screen after loading the MD-11?

We have implemented a short initialization routine that ensures that all elements of the MD-11 panel's systems are up and running and communicating with each other. It sets the engines and aircraft systems to the correct state and in the case of a panel state load properly configures the FMS and so on. During this period you can look around the cockpit, open/close windows, and browse the MCDU pages, but to be on the safe side you shouldn't operate any systems switches, enter anything into the MCDU, open any FS menus, or try to load another panel state.
