Core not autoloading

[eluser]CrazyMerlin[/eluser]
Well the autoload worked fine until of course I got to the loading of CI_DB which does not exist.
On top of that it became a little messy because CI does not follow classname/filename standards with classes being in files named not like the class and different case filenames.

What I need to do is simply initialize the system in my loader so that I can pass the data from forms using AJAX onto the controllers.

How would you best approach this?

Pascal said "The easiest way to do ajax calls is to handle them directly in a regular controller" but I don't see how.

Thanks.
