I don't know about the IDE cables but I know that the Optical drive works just fine for the simple fact that the one I am using is pulled from a working machine, and the fact that I have tried around 7 drives of varying types (i.e. DVD, CD, CD-RW, DVD-CD-RW, so on and so forth). I just finished the bios wipe method that was suggested earlier. I am working on another comp that I just got up and running. When I am done checking that one out I will repost on the findings on the other comp that I am having problems with.
