I'm trying to install Knoppix 6 on a Sony Vaio PCG-3216 with a PCGA-CD51 external CD drive.

I've tried all above and many other things I've found, but somehow after it boots (you can see the linux logo) it can't find the CD anymore. So it boots, and accepts arguments, but after that it doesn't do anything. (I've tried ubuntu too, same problem)

Anybody any idea? I'd love this notebook to run linux!
