In the guide to Unattended Installation of XP where you get windows on first boot to run a batch file, is it possible for a popup to come up asking for you to insert the correct CD and then when you put the CD in, press OK and ot starts using that CD for installation of programs rather than it on the acutual unattended windows CD? This could be useful if you want to change what programs you want to install for different computers and have the programs on different CD's
