Re: [SLE] Configuring to be able to run new kernal with multiple kernal system Was: [SLE] kernel

7 May 2001

      Hello,

If you want to preserve oder kernels (of course if realy need this? I
wonder why you use old ones when there sertainly there is a corresponding
part in the new kernel?) you need to edit /etc/lilo.conf so that you can
boot from other kernels also. For example

prompt
timeout=100
# Default
image=/boot/vmlinuz
	root=/dev/hda2        #or your partition caontaining / file system
	label=linux

image=/boot/vmlinuz.2.2.18
	root=/dev/hda2
	label=linux2.2.18

image=/boot/vmlinuz.2.4.0
	root=/dev/hda2
	label=linux.org

This way you can add many different versions of the linux kernel.

PS:Don't foget to first  backup  your original lilo.conf file.
   There is a greate Kernel-HOWTO on this at LDP (http://www.linuxdoc.org)

Ok, from Erdal's message, this seems simple enough and does include at least
one step I didn't know about, BUT (big but), what if I don't want to upset
my existing 2 kernals ( I run both 2.2.xx and 2.4.0-4BG for different
reasons) I want to add an extra one, what changes to the proceedure do I
need to do?
and, if I download the already compiled SuSE kernal rpm's such as 2.4.2 from
the 7.1's /kernal area how do  handle these?
I'm most likely asking something that's in a howto, if so just give me the
referance please and i'll try that first.
thanks

Hello,
the procedure is quite the same.
Briefly, what I am doing is :
Download the latest and greatest linux kernel from SuSE or www.kernel.org
cd /usr/src
rm linux
ln -s new-linux-kernel linux
cd linux
make mrproper; make clean;
make menuconfig
make dep;make modules;make modules_install;make bzImage
#Make  a copy of your original kernel image, in case your new one have
#some problem
cp /boot/vmlinuz /boot/vmlinuz.org
#Copy the new one
cp arch/i386/boot/bzImage /boot/vmlinuz
cp System.map /boot
#edit /etc/lilo.conf or /etc/chos.conf which one you use
lilo # or chos
If it is all ok, then reboot and enjoy.

Hi all
I was wondering
I want to install the newest kernel on my suse box 7.1 wich by the way I
think is great( after I figured out /etc/rc.conf)
But the suse way still confuses me slightly.
What exactly would I need to upgrade my kernel?
I am used to compiling from source, and would like to compile again if
possible, as I am planning to switch some major servers over to suse.
I am espetially conserned about the packages , like kernel headers and
kernel
...
...
utils and hdparm for my ide drives wich I use quite often.
I am running the stock 2.4.0 kernel currently.
Can someone also explain where I tell my system wich modules to use in
modules.conf ? the suse version looks strange to me and I don't
understand it.
I am learing suse more each day and think I am a convert. ;-)
I like it more and more.
also there seems to be a problem with my live update in yast2 it doesn't
want
to finish and gives me an error message.BTW does anyone know of a mirror
in
South-Africa?
Tnx all
Stefaans
