Within the original OS CD there is no file named DRIVER.CAD, but a file named DRIVER.CAB where all driver are packed.So I suspect, that you don't have an original XP CD. Nevertheless you may try to rename the file from DRIVER.CAD to DRIVER.CAB and see what happens. Hi, Fernando 1: thanks for your time and effort here, it is appreciated. Sry about the mistype. You are correct, the file is .CAB. So... any thoughts as to why nLite can't open it on my computer? Bryan OK, the first time I tried to follow this guide was on a computer with an XP Pro OS, and I encountered several problems, the most frequent of which was that nLite couldn't open the DRIVER.CAB file when it started to burn the ISO image to disk. I never figured out what I was doing wrong in that case. Instead, I followed the process using Vista Home Premium, the same installation it was my intention to replace with a clean installation of XP Pro. It worked, without a hitch. Now, of course, I'm reconsidering whether I really want to go back to XP, as everything about this process went much more smoothly when I did from Vista. Bryan
