I have a legitimate key for XP Pro, but I can’t find my install disk.
More difficult than finding the install disk is finding a floppy with the SATA drivers so that the installer (from the bootable XP Pro CD) can mount my hard drive and install the OS!
Blu, I’ll be happy to mail you an XP Pro cd. 
Alternately, you can download a cd iso from bittorrent.
