kernel can be found in /usr/src/linux/arch/i386/boot, usualy (i386 is the type of processor you have).
If you use lilo as boot loader, you need to make a new section for the new kernel image in /etc/lilo.conf, then run lilo.
It's wise to copy the new build kernel to you boot directory (/boot usualy) with a uniqe name, and then use this kernel image in lilo.conf.

BTW, what has this to do with "Linux Networking"?

Hi,

Yes.... its a bit out of the networking context but anyway (assuming 2.4.7 kernel) :

cd /usr/src/linux
cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.7
cp System.map /boot/System.map-2.4.7

You <may> need an initrd image - see from your lilo.conf if it says initrd=/boot/initrd-2.4.2-2.img or suchlike. If not don't bother, otherwise do :

/sbin/mkinitrd /boot/initrd-2.4.7.img 2.4.7

Then add a section to /etc/lilo.conf

image=/boot/vmlinuz-2.4.7
      label=linux247
      root=/dev/hdb5           <--- copy from existing
      read-only  

(Also copy any 'append', 'initrd' or other lines you have in your existing 'image' block.)


Then update the binary lilo image..

/sbin/lilo -v

Reboot and you should have another option on the boot menu.
