First of all, I apologize if this is in the wrong section. I've been trying to install Windows XP Pro SP3 to my external hard drive, using this tutorial: ehow.com/how_4853554_install-xp-external-hard-drive. html (It won't let me post hyperlinks, so you have to remove the spaces, sorry!) When I got to the part using the "CAB SDK", I tried to download it, but when I looked it up in the MS download center, it said the cab sdk is no longer available, but is now part of the windows SDK (or something). Anyway, rather than download that, I downloaded the set of necessary files from this thread (first post on the 7th page). techspot.com/vb/topic105734-7. html I copied the cd onto an iso using Infra Recorder, put it on my machine running ubuntu, then using "ISO Master" I replaced the necessary files, and then burnt the iso to a CD. I unplugged my internal hard drive, and plugged the external one in. Here's where the problems began. I booted off the CD with the modified xp installation, and it began to load the files. I got the error "atiide.sys not found". I first tried searching the iso I had burnt for "atiide.sys" or "ATIIDE.sys", hoping to just change the caps and re-burn it (thinking that maybe it was case-sensitive). It wasn't there. I then tried searching my original XP disc for the file, I also could not find it. Now I'm stuck. Has anyone here run into the same problem while following this tutorial, or know a fix? Thanks for your time.
