I figured it out. (Someone told me)
Go into your Windows CD (I used xp). Find this file, and extract to a temp folder.
Run the setupmgr.exe file, and when you create the unattend.bat & unattend.txt file, you then put these on your new copy of windows xp (make sure your cd is bootable still).
After that I get a littl bit lost, but seeing how there is a method of doing this, I could probibly google the rest of what I need to know.
Now I also found another problem.
The bat file uses the current computer's cdrom drive letter.
On this computer it is "J:" but if I want to install this cd on a different computer of my drive letter changes, I have to manually change the bat file and re-burn the cd.
So I will search for my answer in google when I get home, or maybe someone will read this post and help out.
rem This is a SAMPLE batch script generated by the Setup Manager Wizard.
rem If this script is moved from the location where it was generated, it may have to be modified.
