How to install the new pre-built kernel?

Ok, so this *should* be a newbie question, but I don't know the answer! How do I install the pre-built 2.4.2 kernel? Should I simply rpm -i k_deflt_24-2.4.2-4.i386.rpm? (this didn't work for me.) I normaly run Yast to select a different pre-buillt, but that only seems to work for the original distribution, and does not allow me to access the updated kernels. I'll be more than happy to read the documentation, if someone could point me to the documentation. TIA, Steve
