It may depend on the broadband provider, and whether or not they "require" a proprietary software installation. For the most part, if you have your broadband connection properly connected to your Win98 machine, you "should" be able to just remove the dialup connection and be done with it. You may have to re-run the Internet Connection Wizard again if just removing it doesn't work. AT&T once said I "had to have their software" installed to connect to their DSL service, and it "wouldn't work on anything earlier than Win2K". Turns out I didn't need any software at all and I got it working with everything back to Win3.11.
