i have been trying to learn how to recompile a linux kernel on Red Hat Linux 7.0..i went through all the steps..but before i make any move i thought i will first get all my questions answered..i took the following steps
step1: i made all the changes using the command , make xconfig.
step2: ran the command make dep
step3: ran the command make clean
step4: ran the command make modules

now this is where i have a doubt..i want to use my newly compiled kernel aswell as the old one..however when i run the command "make modules_install" i know that all my modules in
/lib/modules/2.2.16-22 will be replaced by new ones..i plan to edit lilo.conf to give me a menu to choose from the two kernels..now i know that my new kernel will boot,under the assumption that i did run "make modules_install" and then i did everything necessary to boot the new kernel...however if i choose the old kernel from the lilo menu wont i have problems to boot the old kernel since its modules were replaced by the "make modules_install" command while creating the new kernel?
if so how will i make arrangement for both, the old and the new,kernels to boot without failure as per my choice?

with regards
