[Cooker] What is the difference between kernels?

[Jure Repinc]

There are a lot of kernels available to install. I have 11 uf I do 
"urpmi kernel":

1- kernel-2.4.22.5mdk-1-1mdk.i586
2- kernel-enterprise-2.4.22.5mdk-1-1mdk.i586
3- kernel-i686-up-4GB-2.4.22.5mdk-1-1mdk.i586
4- kernel-p3-smp-64GB-2.4.22.5mdk-1-1mdk.i586
5- kernel-secure-2.4.22.5mdk-1-1mdk.i586
6- kernel-smp-2.4.22.5mdk-1-1mdk.i586
7- kernel2.4-marcelo-2.4.22-1mdk.i586
8- kernel-multimedia-2.4.21.1mm.6mdk-1-1mdk.i586
9- kernel-multimedia-smp-2.4.21.1mm.6mdk-1-1mdk.i586
10- kernel-tmb-2.4.22.3.tmb.2mdk-1-1mdk.i586
11- kernel-tmb-enterprise-2.4.22.3.tmb.2mdk-1-1mdk.i586
I wonder what are the differences between these kernels? Maybe somone 
could add some HowTo to Mandrake Wiki about this.
