Look here for installing hbc and running games from a hard drive.
Dont really need a mod chip If you want to run games from your hard drive. I followed these steps and then used pimpmywii hbc app and updated all my ios's. then installed wiiflow version 1.1 which will allow you to access your games from your hardrive. And You will need to download WBFS manager 3.0 for transfering your games to your hardrive. All these apps are easily found by googling.
