cIOS (Backup Loading)

To understand what a cIOS is you must understand what an IOS is first. After reading that, you will basically know that there are many IOS's on every Wii. They're similar to drivers installed a PC which allow the software communicate with the hardware and vice versa. Every so often, these IOS's on your Wii will get updated via Nintendo or game discs to support more hardware for better compatibility like the USB keyboard. A cIOS is a custom IOS which allows the Wii to communicate with its hardware in ways it wasn't originally intended to. They are released in the form of installers, which use a base IOS, such as IOS 36 or 38, and add modifications to it then install into an IOS slot thats empty, which typically be an IOS above 200.
