it won't let me post url's until I have 5 posts \o/ .. google "dell laptop+linux" and check out the first site on the search or hit feeling lucky.. scroll down to inspiron 9300 on FC4, shows how to setup almost everything on a 9300. Hope that helps.
I got a 9100 and started off with FC1 took me a while to figure out how to make everything run together .. eventually it all did and I'm using debian sarge now. just hang in there and u'll have fun and learn alot. good luck
