IOS5 is a rare stub IOS present in some Wiis. No known functional version has ever been found, although it seems to be the first IOS with WiiConnect24 support, since the SDK refuses to initialize WiiConnect24 if the current IOS is less than or equal to 4 (IOS3 or IOS4) or is equal to 9 (IOS9). It is not known why this check does not include IOS254, although it is possible that IOS254 did not exist at the time.

v514 is not real; it is instead a copy of IOS21v514 that was posted online for unknown reasons, and may be found on Wiis bought from previous modders.

PatchMii's example also previously installed to this slot, since bushing claimed PatchMii installs to this slot, despite it actually installing into IOS254. The version installed by PatchMii is a copy of IOS37 with fakesigning and DVD video enabled.

It is not known whether the IOS5 stub was to target these hacks, or to prevent a functional version from being pirated the same way IOS16 was.
