After retrieving all of the necessary packages, it is time to
upgrade the existing kernel. At a shell prompt, as root, change to
the directory that contains the kernel RPM packages and follow
these steps.

It is strongly recommended that the old kernel is kept in case
there are problems with the new kernel.
|
Use the -i argument with the rpm command to keep the old kernel. Do not use the -U option, since
it overwrites the currently installed kernel, which creates boot
loader problems. Issue the following command (the kernel version
may vary):
rpm -ivh kernel-2.6.9-5.EL.<arch>.rpm
|
If the system is a multi-processor system, install the
kernel-smp packages as well (the kernel
version may vary):
rpm -ivh kernel-smp-2.6.9-5.EL.<arch>.rpm
|
If the system is i686-based and
contains more than 4 GB of RAM, install the kernel-hugemem package built for the i686 architecture as well (the kernel version might
vary):
rpm -ivh kernel-hugemem-2.6.9-5.EL.i686.rpm
|
The next step is to verify that the initial RAM disk image has
been created. Refer to Section 37.5
Verifying the Initial RAM Disk Image for details.
