RPM.
The way I recommend is to install Redhat's kernel RPM (kernel*.rpm). Usually
there is no reason for you to ever compile your own kernel, because Redhat
includes almost every conceivable feature in their kernel as a module, which
is very convenient.
If you do want to compile a kernel (e.g., one of the missing features in
Redhat's kernel is NTFS support - say you reall need that...), install
Redhat's kernel-source.* rpm, which opens into /usr/src/linux-* - then
go there, and do your stuff (make mrproper; make xconfig, etc.)
Again, that's kernel-source.rpm. *do not* use kernel-*.srpm unless you
know what you're doing. Also, I'd strongly recommend against taking a
vanilla kernel from kernel.org and compiling it yourself, unless you know
what you're doing. Redhat adds a lot of patches into the kernels it includes
in its distributions, and some of them perhaps are needed to go well with
the user-space programs they distribute. A kernel from kernel.org is likely
to work just fine, but why take the risk (unless, again, you know what you're
doing, and deliberately want to experiment with a newer kernel).
P.S. After installing a kernel with
rpm -Fvh kernel-1.2.3.4.rpm
*DONT FORGET* to run lilo again! If you do forget, your system might not
boot up the next time, and you'll need to boot using a rescue disk (or the
original Redhat cdrom).
