Resolved Slipstreaming Service Packs

I have an original XP Pro CD and I want to integrate SP3. However, Service Pack 1a is a prerequisite to installing Service Pack 2 or Service Pack 3. Is it possible to slipstream SP1a and then slipstream SP3?

 

According to this:

 

Yes. Just slipstream SP1a, then follow up with SP3.

My notes are here: Slipstreaming Windows XP Service Pack 3 and Create Bootable CD

 

Prior to any replies I made an iso with just SP3 slipstreamed...testing the install in progress. We'll see if I needed to use sp1a or not. So far, so good, disk is formatting. I figure if no joy it will error out on first boot.

 

Well, I found (as I wrote in my article):

 

Well, so far all is well. The install went smooth and all functionaly is intact. There's no activation with this one because it's a volume license. Now I can use this cd for reinstalls in the client's business if needed. It will save a lot of time and reboots as I won't have to install service pack 1a followed by sp 2 & sp3. In the past, when installing service packs for them I'd always get the warning "you must install service pack(previous) prior to installing this one ". Even MS Security Essentials installed fine.
