Boot2 is basically a process which happens before the system menu starts up. It is run by boot1, which is run by boot0. If you are installing bootmii, install it as boot2 rather than IOS, as it is a better version. If you want to know more about boot0, boot1, and boot2, look it up on wiibrew.org
Be sure to install the homebrew channel FIRST. I suggest you also install priiloader too. Make a NAND backup too and make sure you have at least 1gb free space on your sd card. Best if it is a Sandisk 2gb standard SD card.
