Hi there
You need ndiswrapper and your windows drivers. You should visit the ndiswrapper page at sourceforge.net (
Here) and read carefully all of the info.
I was a total newbie not so long ago, but have now configured the wireless card on several machines with ndiswrapper. Read all of the guides carefully, and you'll get there. If you have specific problems when following the instructions, then post back here what problems you have had.
