1.) The Knoppix V4.0 DVD did not boot and hung. In debug mode i found that there were ACPI warnings "executable code found at module level". The solution to this was to remove the USB card reader I had plugged in. After that the boot sequence finished ok. I do not know if this error is worth being tracked. I cannot really make a connection between ACPI and a USB device. If anyone is interested in the issue I will send additional data.
2.) Knoppix needs a povray raytracing engine if it is to have KPovModeller. Here is the error:
i) Load up Graphics--> KPovModeller. ii) (It comes up with a basic scene). iii) Hit View--> Render iv) It gives the error message: "Couldn't call povray. Please check your installation or set another povray command."
A discussion of possible workarounds (including my wishlist) can be found at: http://www.knoppix.net/forum/viewtopic.php?p=88147#88147 . I would note that I entered it into a feature request at that forum and was directed to report this as a bug. Paipix 3.6 FWIW does not give this error because it has a povray engine.

Knoppix 4.0 booted from DVD:
- No sound. When I go to "Kontrollsystem - Soundsystem aktivieren" I get the message: Error while initializing the sound driver, device /dev/dsp can't be opened (No such device). The sound driver doesn't seem to be installed. It's a Soundblaster AWE 64 Gold, with Knoppix 3.4 it works.
- Can't edit Grub bootloader with the system tool "Systemstart". The Bootloader can't be found.
Knoppix 4.0 installed on hard drive:
- No sound. Same problem as above.
- Now the Grub bootloader is found, but the entry of Windows XP starting isn't displayed. Changes doesn't affect anything, either.
- Open Office 2.0 doesn't start (Only approximatly 6 GB is knoppix big on my hard drive, I thought it should be around 10 GB. Perhaps some files are missing.).
- No USB hard drives are getting detected.
Perhaps you can fix some of these problems by hand, but it would be nice, if it would work out of the box. I know, that knoppix isn't made for installing on hard drive, but many people do so and perhaps it is not so much work to fix the problems.
