Thanks for your attempt to help me. I have just one more question at this time...
I had loaded the cx18 driver twice before and dmesg did show that the card was recognized. In fact, I actually did have video at one time. But after making a mess out of my system I reinstalled everything and have not been able to get the card recognized since. So now after the information you gave me about pci buses, I tend to believe that I have a hardware issue or something related to packages. It now seems obvious to me that I did something to change my system that is causing the problem. Does this sound reasonable to you? My problem is that I can not remember what changes I may have made to my system. Here is a list of possible changes that I wonder about. Please tell me if any of these may be related to my problem. I. Could the problem be related to using a differant kernel than I originally used? 2. Could it be that originally I used the live cd installation and now I am using the alternate cd installation? 3. Could it be related to installing a second hard drive on my system and at differant times I have it enabled or disabled? 4. Anything else you may be able to think of that I may have done differantly?
