Knoppix 7.3 CeBIT Edition

Knoppix PXE Boot Server

You can set up Knoppix as a boot server for the local network, so that other computers, acting as clients, can boot from the server, access the Knoppix medium remotely, and run programs locally. For this task, Start KNOPPIX Terminal Server in the Knoppix menu. Setup is easy and straightforward; you basically just confirm the allowed network range and boot options for the clients. In this way, you can run an entire classroom with just one physical Knoppix medium. In version 7.3, I have changed the terminal server setup to generally provide 32-bit clients (64-bit computers still boot in 32-bit compatibility mode, of course), even if the host system was booted with the knoppix64 boot option. This setup is the most compatible for clients, and does not require clients to specify the kernel with which to boot.

Boot Problems?

Normally, Knoppix does not require any boot options to determine the correct settings for your hardware, graphics cards, and so on. However, with so many different chipsets and combinations thereof, it is sometimes necessary to disable a feature or hardware component temporarily to reach the productive desktop stage [1].

Some common boot options for hardware problems are listed in the boot help that you can reach by hitting F2 or F3 in the boot screen; others are listed in the text file knoppix-cheatcodes.txt inside the KNOPPIX directory. If the desktop gets stuck at the point that the 3D composite window manager Compiz should start, try booting with

knoppix nocomposite

knoppix no3d

to disable the graphics subsystem's "composite" extension, or just to avoid starting Compiz.
