The other thing to consider is if it's running XP it uwill not/u migrate to
a new mobo. You must reinstall. Any apps that have significant registry entries
also will need to be reinstalled.

If you're running 98 and change the mobo you need to start in safe mode and
remove all references to the old mobo resources. If you don't you might get
nagged by a BSOD once in a while. XP won't even get into safe mode with such a
drastic hardware change. While the hardware change bothers 98, if you can
manage not to reinstall it your apps will run right. The exception might be
certain games if you wind up with a different vidcard.

Actually anyone who's still running 98 is doing so for a very good reason.
