You basically use your connection details and set up a networking connection manually. If you search google, you'll find lots of info on it. Next time I go to my mates house, i'll take a note of his settings because it's been a while since I did anyones internet.
But do remember, AOL WILL tell you it's not possible. I had this from two support techs until I got one decent one who was able to explain. Just tell them you want to set it up without the AOL software.
