Now that you have a verified and properly burned disc, the next step is to try to find the right cheat code or cheat codes that will allow you to boot. One popular code that often helps with video devices and blank screens is xmodule=vesa . I know of no universal answers to the problem of finding the correct codes though, sometimes it's just trial and error, particularly when your hardware needs multiple codes (I needed acpi=off and noscsi with one notebook for several releases of Knoppix and that was very hard to find). Beyond reading the cheat code documentation, a couple more things that you can try are:
  • 1 Try booting in failsafe mode. this almost always boots, but usually doesn't provide a very useful system, as things like the network and even the mouse may not be detected and therefore not work. But it's a good chance to at least see Knoppix running on your system.

    2 Read about the cheat codes and then boot in expert mode. Take good notes about how you answer each of the questions. If Knoppix hangs again, reboot, go back to the last question and try changing your answer.
