HP doesn't ship disks for XP? I have never owned an HP, but that would be criminal to me.
This is why I build my own with full applications, not image disks. I support Dells at work.
I just learned something. Found this on HP's site:

I knew you could do a Restore because XP is on a protected partition, and nowadays some users can make Recovery discs.
(HP's site sucks. Things are spread everywhere, and if you bookmark things for your model it'll likely disappear, as mine did when they did a site redesign a few years back. If you find something noteworthy, better save the page).
HP has the XP recovery installed on the computer...in files located in an unaccessible area. You are suppose to create your own recovery disk when you start your computer...but who actually does that besides the true computer geniuses?
