make config ; make dep ; make clean ; make zImage
This will create a compressed kernel in /usr/src/linux/arch/i386/boot
called 'zImage'. Copy it over to /boot and then add it to /etc/lilo.conf
as the first image. This will boot the new kernel as the default but
leave you with the RedHat vmlinuz in place. For example, here is my
lilo.conf. I created a new 2.0.26 kernel and listed it first. But the
old vmlinuz is still there. So, if something is wrong my new kernel, I
can hold down shift, get the LILO prompt, and boot the old kernel (which I
know works). (Remember to always run '/sbin/lilo' when you make any
changes to /etc/lilo.conf!)
