Subdomain multisite installations!

Okay, so I have been researching this.

I am trying to find out how to have a subdomain formatted multisite installation in a directory folder on my hosting.

I have already set up the Wildcard A Host, but it keeps taking all created sites to a different WPMU multisite I have installed on my hosting servers root directory.

How can I make a wildcard supported, subdomain formatted multisite residing in a directory other than root, on my servers hosting?

Please help me on this....
