Configuring an AEBS in Windows 98
If you want to configure an Airport Extreme Base Station under Windows, according to Apple you need 2000 or XP, which is not much use if you are running Windows 98.
Jon Sevy makes a program that runs under Windows 98 and can be used to configure an AEBS.

You will probably need to install Java.
