9.7 Installing the Kernel
After the kernel is compiled, it must be installed so it can be booted.
I x86
If you use LILO, LILO must be updated as well. To prevent unpleasant sur-
prises, it is recommended to keep the old kernel (e.g., as /boot/vmlinuz.
old), so you can still boot it if the new kernel does not function as ex-
pected: J
cp /boot/vmlinuz /boot/vmlinuz.old
cp arch/i386/boot/bzImage /boot/vmlinuz
lilo
I x86
The Makefile target make bzlilo performs all three of these steps. J
Note
If you use GRUB as the boot loader, it does not need to be rein-
stalled. Simply carry out the first two steps to copy the kernel to
the right location in the system.
Note
BootX: The above-mentioned file vmlinux must be copied to ‘Linux Ker-
nels’ in the system directory. Next, when BootX is started, the new
kernel must be selected before clicking ‘Save to prefs’.
RS/6000 (quik): Copy vmlinux to boot/ and adjust /etc/quik.conf.
RS/6000 (disk): Copy zImage from /usr/src/linux/arch/<arch>
/chrpboot to DOS floppy disk.
Now the compiled modules need to be installed. Enter make modules_-
install to copy them to the correct target directories in /lib/modules/
<version>/. If the kernel version is the same, the old modules will be
overwritten. However, the original modules can be reinstalled together
with the kernel from the CDs.
