I've seen that there are two types of Recovery disk sets for Dell computers I've come across that had XP installed on them originally.
The type of Recovery disk set I've seen more often is ....
- the first disk is an XP Re-installation CD
- the second disk or more than one disk has the Drivers needed for the model and the Applications (programs) that were originally installed.
In that case the contents of the XP Re-installation CD are almost identical to that on a regular Microsoft OEM XP CD, except that certain OEM.* files have been modified internally so that the CD can only be used with the same model / mboard / a small group of models / mboards that were made at the same time
You have to supply info that you would need to supply if you used a regular XP CD - you need a Product Key for XP's Setup, you use the one on the Microsoft label that's on the outside of the computer case, and you have to Activate Windows yourself, you are probably NOT prompted to insert another disk when Setup is finished, and you use the other disk(s) to install drivers needed for the model ( there are no additional drivers that do not come with Windows for your model on the XP Re-installation CD ), and, optionally, Applications.
The other type of Recovery disk set I've seen is the traditional type - the disk set is a multi-disk archive that was made for your specific model / a small group of models that were made at the same time. Not much input is needed from the installer.You are prompted to insert the second disk after the first one has finished loading, etc. The installation has a Product Key built into it, all needed drivers are installed, Applications are installed, and Windows is automatically Activated,when the set of disks has finished loading.
