Others may disagree but i find 2.4 more stable anyhow.What is it that that you need to know about running 2.4?The kernel is on the cd's.Just go to rpmdrake in KDE and search for kernel.The kernel source however,will have to be downloaded and installed before you can install and drivers.Here's a link to the kernel source im using...default version of 2.4.25-2mdk in mandrake 10.

Im not exactly a linux expert but will be happy to help if you need anything else..
**i belive there 2 or 3 different versions of the 2.4 kernel you can choose from,whichever one you decide on you can visit the link above and search for the matching kernel source.You WILL have to have it.
