You can try one of the following but if you have at least 256MB of RAM and a decent sized hard disk, I would recommend an upgrade to XP as you'll get a lot more stability and compatibility with most of today's accessories. If not, here are the alternatives:

Anapod -> Anapod Explorer™ iPod Software, iPod Backup, iTunes Alternative, iPod Transfer, iPod Manager, iPod Management, iPod Explorer, iPod Utility, iTunes Replacement, iPod Copy, iPod Freeware, iPod Managing, PC Software, Windows Software, Windows Vista Soft
Win98 driver for iPod -> http://saviomd.googlepages.com/ (not sure if this will work, try at your own risk)
Another one -> iPod USB driver for Win98, 98SE
