Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I'd like to compile a kernel 2.2.19 for some programs of a PC-embedded I have. Now my question is
if I compile it normally will it overwrite or affect the kernel 2.4.27 I'm actually using?
Is there a way to compile another kernel and other programs for a kernel that is not the one u are using?
I think I saw in the GRUB (or LILO) screen something about using another kernel, but don't know how to do that.
If you just want to compile the kernel, google for 'Linux Kernel HOWTO'. It will help a lot.
After compiling, you will have to install the kernel and modules, also make sure to use proper version of gcc when compiling. You can find that info in the readme's or release notes. Finally, you will have to add your kernel in /boot/menu.lst (for grub) so that you can choose it at boot time.
You can have multiple kernels for use, the default behavior when installing a new kernel is to add it to the list, not add it and remove the others.
A major area of concern is why you would want or need 2.2.19. Also, how you have knoppix running 2.4.27. That must be like the first generation of knoppix?
The current 2.2 kernel branch is 2.2.26, and 2.4 is 2.4.32. If you are going to do a new kernel, you may as well at least make it the 2.6, which is now 2.6.17.
If you have something that has to run on 2.2, it probably was abandoned in favor of better things years ago. It may well be worth your while to check if newer versions of the software you are looking to run exist.
The App is about data acquisition using the comedi drivers and should work in a PC-Embedded (tiny kernel and tiny space )
And since the app "used to work" under 2.2.19 it's one of my main options although I'll try some others
