If you're getting a new computer and want to use Windows, go for XPee. I mean, I seriously don't see any point in installing 98 (SE or not) on a new machine, except enjoying fighting to get drivers to work properly (USB, USB 2.0), lack of support in new programs, complete lack of security updates (MS stopped supporting 98 a while ago).

And to answer your question, you need the 98se disc to install it, it doesn't exist in thin air for you to install And since you won't find it in stores...
Same goes for Works. Get <a href="http://www.openoffice.org/">OpenOffice.org</a> instead, anyway.
