| Despite the major version being 0.7.6 as seen in the SDK, the title ID is IOS3. IOS in beta used the IOS0 title ID, then as it neared release they changed to IOS3. Later on it changed to IOS4 which is the first one that got shipped at retail. IOS3 is used in the factory and comes preinstalled as a stub on [[RVL-CPU-30]] Wiis because of it; later version is a stub. The older version is lost but we know it exists because of the SDK.  

| IOS3 is found as a stub on [[RVL-CPU-30]] consoles, and appears to be used by newer versions of the 122E disc. The version number used by 122E is unknown.

| We only know it exists because it's listed in the SDK. The IOS5 going around the internet is a modded version of [[IOS21]] and is not real, the legit IOS5 will probably never be found. An IOS with the same title ID exists as a stub on some Wiis, probably same situation as IOS3 above where it's used for factory titles or possibly due to the aforementioned hack distributed under the IOS5 title ID.
