Fun Fact! I mentioned IOSs and cIOSs before, "the Wii console uses the 'IOS' system to communicate with the hardware, it's like a driver (compared to Windows). It contains information and communication tools (like how to access the Disc drive, how to access USB, read the savegames data stored on internal memory, etc.)" ~Cyan. If you're curious to learn more about IOSs or cIOSs, a thorough explanation can be found in Cyan's IOS Explanation post.
