Windows XP MCE 2005

I'm trying to install Windows XP. The only disc I have for it is a Home SP2 disc and the key I have is for MCE 2005.

During the installation, it doesn't check the key on the internet, right? So, does anyone have a key I can use, even if I can't activate it? I just need a key that will work for the installation.

oh, and to install ie7, download it from microsoft (not via windows update) or softwarepatch.com, and disable your network adapter during the install.  it will wait for a minute or two on the "Validating..." screen and then successfully install.
