If you boot with a 98 CD/bootdisk and try to run setup off the XP CD you get "cannot be run in MS-Dos mode" or something, but if you boot with a 98 CD, and then browse to the I386 folder on the XP CD, and then type NetSetup it will install like it should.
And then it should ask for your Win98 CD to verify that you are in fact upgrading, even though the harddrive was formatted.
With the 98 Upgrade you could fool windows into thinking that it was upgrading by taking a formatted harddrive, making a Windows Folder, and then making a 0 Byte file called win.com and it would think that it was upgrading.
You could also use a full version as an upgrade by renaming win.com to something else like win.co_
