| The title ID used by the System Menu is what IOS2 would be, so the System Menu is in the IOS2 slot. Note that this is the only time a non-ARM binary is placed in an IOS slot. Switching to this slot loads the System Menu IOS.

| Despite the version being 0.7.6 as seen in the SDK, the titleid 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 some wiis because of it; later version is a stub. The older version is lost but we know it exists because SDK.

| Previous versions only had minimal drivers (lacking KD, WL, WD, SSL), and were used during manufacturing. v3's timestamp is Aug 10, 2006; it was used by the [[Prelaunch System Menu]] present on pre-launch kiosk Wiis that shipped without a full System Menu. v259 was used on Korean Wiis at some point, although it is unknown what, if any, purpose it served. v1's existence is known through remnants in the Startup Disc NAND. v65280 is a stub; at one point, v3 was on CDN, likely by accident, but it was replaced with the stub version.

| 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. IOS with the same titleid exists as 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.
