He there.
So how limited is limited? Do you have internet connection? Do you have graphics?
Well the thing is, I know how to install an kernel, I have done it many times before. But I recoment you get an official kernel from suse, rather then the way I do it, i.e. go and fetch an kernel source tarball from kernel.org and compile it my self.
I don't know what you can run and what not, booting from the cd, but if you can run yast, see if there is an option for installing an kernel. I'm not to familiar with yast, so I can't tell you how to do that.
If you have internet connection, go to the suse site (
www.suse.com) and see if you can get an kernel from there. I went there my self and I THINK
this is what you need. It's an source kernel rpm of the 2.4.20 kernel. It will install the kernel source. After that, you will have to build the kernel your self. You do know how to install an rpm, do you? It's "rpm -i <package>"
It's hard for me to guide you through the build proces because I don't know what you need/want. But
here is an document describing how to do that. If you do that, do not forget to compile reiserfs support in to the kernel!
Alternatifly, you could re-install your system, but I would recomment you try to safe it. What do you have to lose? And plus you will gain experiance.
Well, good luck and tell me how it goes.
