A couple of suggestions for slipstreaming:
1. Download and install nLite, which is a freeware utility that will create a bootable XP installation disc, with service pack integration. It also allows for permanent Windows component removal by your choice, integrations of drivers, tweaks, and hotfixes. This is an awesome utility with an easy GUI.
2. Call MS and ask for a replacement CD for Windows XP with SP2. I had my original retail WinXP installation disc from 2001 (I think) and it had some scratches on it. The first time I called MS they wanted to charge me $25 plus shipping. I called back a few hours later, got a different agent, who never mentioned a fee. I just had to provide the part number from the cd, pay a nominal shipping charge, and I had a new installation disc with SP2 within the week. I used this one to create my nLite install disc.
A few additional thoughts: I'm a software junkie, and some of my installations of alphas and betas have resulted in the need to reformat and clean install windows. I've learned the hard way to create a restore point and / or a ghost backup before each new installation and to test my other apps before moving on. The last time this happened to me, my system was complete, when I linstalled the Stardox applications (Windows Blinds, Icon Packager, etc) and Quciken and MC 11 were among the programs that were not at all happy.
