Alright, I was wondering if you can install Kernals whenever you would like. I mean I'm not sure if there is a compatibility issues between kernals. Right now I have a 1.1 Ghz kernal on and I was wanting to go to a low voltage kernal with higher speeds and maybe to save battery life. I know that those ideas might contradict each other but the battery life is the more important of the too. I might stay with the 1.1 Ghz because I have no problems with that speed but just change to low voltage. Anyways, that is not important. Is there compatibility issues with loading a different kernal. I was thinking about ChevyNo1-1.25Ghz-medV-7slot-update.zip . I just don't know if I would have to change the Rom to his.
