Modules Override

Wednesday 05 October 2005 7:49:03 am

hello,
i need to create a new setup module as an extension.
When i tried to do this, the only way to make my modules start was:
-rename the exinting setup folder (in kernel folder) or delete it
-put my folder (with my custom setup) in the extension folder and activate it

How i can do this without manipulate the original setup folder?
It's possible to override only some step?

Thx you
