Yes I have a real XP CD. In fact I have several. I have a Full Retail one, a Upgrade Retail one and several Microsoft "real" OEM versions of XP. What I found out, to digress a little is that you can take any OEM CD (not a restore CD but a real Microsoft OEM full version XP CD) and use it as long as you enter a Product Key appropriate for the machine you are installing it on. In other words although the Product Key is tied to a specific machine and will make you activate Windows again if you make too many hardware changes, the actual installation CD's themselves are all the same. Before I found the slipstream instructions, I had already paid Microsoft $ 28 a pop to replace all my Microsoft XP OEM CD's with ones including SP3. If I would have realized earlier that they were all the same I would have bought fewer of the SP3 replacement CD's!
However Microsoft says they never made and that they won't ever make Full Retail or Upgrade Retail CD's for XP Professional that include SP3.
So I had made a Slipstreamed CD for the Retail Upgrade version when the computer that it is tied to had a failed hard drive last month using this procedure: http://www.howtohaven.com/system/slipstream-xp-service-pack-3.shtml
In the IBB file/script they have you create using those directions, it looks like they were using ISO9660 + Joliet since they have these lines in there:
VolumeLabel_ISO9660=HTHSP3
VolumeLabel_Joliet=HTHSP3
plus some Restrictions_Joliet lines
At the time I never though about the Joliet issue... I just followed their directions and it worked. The resulting CD successfully installed XP SP3 on the new hard drive.
Then this month another machine's hard drive failed, and I forgot where I had found the instructions last time and found a new set of instructions I found here: http://www.pcmag.com/article2/0,2704,2325399,00.asp
This person who wrote those instructions explicitly says in his directions:
So that statement in his directions is what caused my concern about Joliet, since your dialog box ...when I was trying to burn the file created by using his directions, said that it appears I was trying to make an OS installation disk etc. and some of my setting were incompatible.
Strange that he should say about making sure you are using Joliet since now I learn from you that Microsoft doesn't use Joliet! Thanks for pointing out your excellent (actually the best of all of them I have found) tutorial on how to do this! I hadn't seen that before. I did get the dialog box asking to let your program change my settings to make an OS Operating System CD and after reading your tutorial it appears I did everything correctly and the resulting CD does boot and look OK as least as far as the opening screen... I haven't actually tried to go through the entire installation process yet, but it sounds like it is going to be OK since I got no error messages and it boots from the CD OK.
Now I am wondering, and perhaps you know, if the Retail and Upgrade edition physical CD's are actually the same and just behave differently depending on whether you enter a Full Retail of Upgrade Retail Product Key during the installation process (ie look or don't look for a "qualifying product" depending on what Product Key you enter) or is ir really necessary to create different versions of the slipstreamed CD as I have done... one using the Full Retail CD and one using the Upgrade Retail CD?
As for the Padus issue, I'll check back later then as you suggest. Thank you very much!
