I have a Knoppix Light 4.0.2 LiveCD that came with a book I bought called "Hacking Knoppix". When I try to boot from the CD I get to a screen with two penguins at the top that says:

Welcome to the KNOPPIX live Linux-on-DVD

Scanning for USB/Firewire devices... Done
Can't find KNOPPIX filesystem, sorry.
Dropping you to a (very limited) shell.
Press reset button to quit.

Additional builtin commands available:
cat mount umount
insmod rmmod lsmod
knoppix#

If I boot with the command:
knoppix debug -b 3

I get to a # prompt, and everything seems fine. If I 'exit' from this stage, I get the above message about the KNOPPIX filesystem. What am I doing wrong and do you have any suggestions as to how I can fix the problem?

This is not a DVD, but a CD and I am attempting to run it on a Dell Latitude E6500. I am wondering if the hardware in this machine is too new and unkinown to KNOPPIX, yet.

I also just tried to boot it up on my old laptop (Dell Latitude D610) and it got further, it seemed to be finding hardware and the CD, but it finally came up with a blank screen.

Thanks for any and all help.
