But today Microsoft has not provided such. And the install steps vary widely depending on your machine.

For instance with under 127GB drives on the older Parallel ATA (PATA) drives this method might be used. http://www.google.com/search?hl=en&q=install+xp&btnG=Google+Search (pick one.)

But with over 127GB drives you best have that XP SP1 or better yet XP SP2 CD.

-> What happens if you have a SATA drive? It gets harder. See links like http://www.google.com/search?hl=en&lr=&q=install+xp+on+SATA+drive

--> Even more fun if you have a SATA RAID drive. I won't go there.
