Microsoft made the assumption that everyone who would install XP had a PC that could boot off of the CD-ROM drive.
So, no floppy option was included in the release.
Microsoft does have a utility to create the startup floppy disk set.

Remove any spaces from the pasted link.
The link is for XP Pro. You need a different file for XP Home.

Further, if your version of the XP CD includes SP1, you need a different set of files.
Note: if all you need is a bootable floppy, you can create one as a floppy format option.
