I see a lot of people saying they are running so and so's ROM with so and so's kernel. Is there something one has to do to install a separate kernel or am I right in the idea that most devs who make ROMS also make special update.zips that already have a certain kernel installed into it, so for instance, PETE has BB with chevy's kernel in it but it's still installed by naming it update.zip and installing the whole deal. Correct? Or is there something you do after installing a ROM to put a special kernel in it?
