"u won't be able to find the right driver when upgrade to win xp"
XP should have no problem getting the chipset/audio/video drivers right for an old 500. It recognized everything in my P2-333 machine.
If the OP's machine has at least 256MB of RAM, upgrading to XP would be a much better choice than sticking with 98.
