Building a new kernal

[John Hoffman\\]

Hello   I'm having some problems figuring out the documentation for rebuilding the kernal for redhat.  Actually I managed to rebuild it ok the problem is installing it.   I have two new files.  vmlinuz and system.map   In my /boot directory I have the following files   /boot/System.map-2.2.12-20 /boot/module-info-2.2.12-20 /boot/vmlinuz-2.2.12-20 initrd-2.2.12-20.img And in my lilo.conf I have the following   boot=/dev/hda map=/boot/map install=/boot/boot.b prompt timeout=50 default=linux   image=/boot/vmlinuz-2.2.12-20         label=linux         initrd=/boot/initrd-2.2.12-20.img         read-only         root=/dev/hda8   So here is the difficulty, I can figure out what do do with image.  I create a new lilo entry and set image to my new vmlinuz.  What I don't know is where do I get another initrd for my new build?  what do I do with my new System.map?  And where can I get another module-info for my new build and how do I put it in my lilo.conf?  Seems like I'm missing some steps here and the docs are a little inadequate.   I guess I could just replace all the files in the directory with my new ones but that seems so fatal.  I remember playing with linux several years ago and I could have several kernals installed and select the one I wanted with lilo.  So if I got a bad kernal I could just reboot off the old one.  Has this changed?   BTW I also tried to make zlilo and this just put a copy of system.map and vmlinuz in the root directory...   Anyway any help would be welcome.   John
