There is a way of running Setup without going through the normal restore CD gubbins that they put on. But you can only do it if you have the i386 folder - if you do have it here's what to do:

Boot up with a Win98 Startup floppy with CDROM support, then navigate to the i386 folder on the CD (at the A:> prompt type the letter of the cdrom drive, then "CD i386" without the quotes) Then at the X:\i386> prompt (where X: is the letter of the cdrom drive) type "Winnt.exe". That will run the normal Windows Setup.

You can get a startup floppy here:
