Question concerning WinXP Pro Upgrade

I'm getting a new comp, and just purchased WinXP Professional Upgrade. I also am getting a SATA hd, and have been told you cannot install Win98 onto a sata hd, and I intended on upgrading to WinXP Pro from Win98. In order to use the XP Upgrade, do I have to have Win 98 installed on my system, or is putting the cd in the drive during WinXP Pro Upg sufficient? In short, will I be able to install WinXP Pro on my new comp w/out installing Win98, since I cannot. Thx for the help.
