* 0 Seconds - unit is powered on bootrom begins execution

* 2 Seconds - bootrom attempts to initialize the NAND. If the NAND is successfully initialized, the bootrom launches the firmware loaded from the NAND [[FIRM]] partition which handles booting the rest of the system. The ARM11 kernel loaded from FIRM then loads the [[NCCH#CXI|CXI]] ARM11 system modules embedded in the kernel. If the NAND cannot be initialized, (i.e. the NAND chip is not connected/damaged etc) a blue error screen similar to the screen above appears.

* 3 Seconds - all essential hardware is active. The [[Process_Manager_Ports|PM]] module launches [[NS]], [[NS]] then launches the [[Configuration Memory#ACTIVEMENUTID|current active menu]]. For retail units this menu is usually the [[Home Menu]].
