Today I wanted to do an "update" to my wii, since some custom homebrew/firmware was kind of outdated. I went to filetrip and downloaded cios 38 rev 19, and also cmios rev5 ( I had rev 18, and cmios rev 3 ). I installed ( via network ) cios38 successfully, and I just used the default settings ( I think I used ios 249, but im not sure ). Then when I wanted to install cmios, it told me what ios base I wanted to use, and the default one was ios 249, so I was wondering what this could do to my system. Do I just install it with the defauult settings or do I use another ios? I really dont remember which base I did use when I installed my first cios38 ( it was rev14 ), and the first cmios (rev3).
