Well, you can install that source rpm with "rpm -ivh
kernel-2.0.32-2.src.rpm", but that's not what you want to do.  Red Hat
has rpms of the kernel source & headers that install to
/usr/src/linux, which would be a better choice (the .src.rpm will
install the kernel source tar file to /usr/src/redhat/SOURCES/ or
something), but that still isn't the best thing to do.

Here's your best bet...  Get the following file:

    ftp://ftp.kernel.org/pub/linux/kernel/v2.0/linux-2.0.33.tar.gz

(Obviously, replace the above file with whatever the latest stable
kernel is.  'finger @linux.kernel.org' or look for a LATEST-IS-* file
in that directory to find out what the latest version is.)

Anyway, for that kernel, do the following to build it:

    cd /usr/src
    rm linux
    mkdir linux-2.0.33
    ln -s linux-2.0.33 linux
    tar -zxvf linux-2.0.33.tar.gz
    cd linux
    make config # or "make menuconfig" or "make xconfig", if you prefer
    make dep && make clean && make zImage && make modules && \
    make modules_install
    cp -i arch/i386/boot/zImage /boot/vmlinuz-2.0.33
    # Edit /etc/lilo.conf with your favorite editor.  I like vi.
    # Sample lilo.conf follows.
    vi /etc/lilo.conf
    /sbin/lilo # to reinstall lilo

And you're done.  :-)

BTW, here's a sample /etc/lilo.conf.  You'll want yours to look
something like this:

### start here ###
# set this to your boot drive
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
# set this higher if you want to boot another OS
delay=10
timeout=2400
read-only
# set this to your real root filesystem
root=/dev/hda3
image=/boot/vmlinuz-2.0.33
        label=2.0.33
image=/boot/vmlinuz-2.0.32
        label=2.0.32
# If you want to boot Windows 95 or something,
# use an entry like this (uncommented, obviously):
#other=/dev/hda2
#       label=windows
#       table=/dev/hda
### end ###

There.  That should get you started.  :-)
