IOS 2.02 for WiiMC

I read about upgrading to WiiMC. Found it on HomeBrew Browser. But also read where I need IOS 2.02. I tried to download to USB drive, but couldn't see how to load it on Wii. Is it available via HBB or only via computer?
Is the only way to load it via SD (if USB drive doesn't work).
My old desktop doesn't have an SD slot so it takes a few gyrations to get it on there.
Thanks

You must download the cIOS 202 installer with a computer, put it on your SD card just like any other application, and run it from the HBC. You probably could use a USB drive instead of the SD card if you prefer.

Thanks. Had to load DopMii as well to get this to load. but otherwise ok.
