* 2 seconds - ARM9 bootrom attempts to initialize the NAND.

* 2 seconds - ARM9 bootrom attempts to initialize the NAND.

**If the NAND is successfully initialized, the ARM9 bootrom loads the [[FIRM|firmware]] stored in the NAND [[FIRM]] partition which handles booting the rest of the system (if verification for NAND firm0 fails, the ARM9 bootrom will attempt to use firm1 instead). The ARM11 kernel loaded from FIRM then launches the [[NCCH#CXI|CXI]] ARM11 system modules loaded from FIRM (i.e. sm, fs, pm, loader, and pxi). (Note that the ARM11 kernel does not handle any encryption/RSA verification, this is handled by the [[FIRM|ARM9]].)

**If the NAND cannot be initialized (i.e. the NAND chip is not connected/damaged/etc), a blue error screen similar to the one above appears.

* 3 seconds - all essential hardware is active. The [[Process_Manager_Services|PM]] module launches [[NS]], [[NS]] then launches [[ErrDisp]] and the [[Configuration Memory#ACTIVEMENUTID|current active menu]] via PM module. For retail units, this menu is usually the [[Home Menu]]. NS will [[NS#Auto-boot|auto-boot]] titles instead of launching ErrDisp/Home Menu, if auto-booting is needed. Note that the PM module first launches the module dependencies when launching a process, prior to actually launching the process. Further details on the Home Menu startup process can be found [[Home_Menu#Home_Menu_startup|here]].
