I assume you want to boot Mandrake with a Mandrake-tweaked kernel, and Debian
with a Debian-tweaked kernel, yes? (Recommended.)
You'll have to do more than the last poster implied.
First, make a copy of /etc/lilo.conf before you start screwing with it.
cp /etc/lilo.conf /etc/lilo.conf.saveass
Now, the easiest thing is to pick ONE distro to manage your boot loader.
Either Mandrake or Debian. You'll drive yourself nuts trying to keep up with
two copies of lilo.conf on two different partitions. Let one manage the boot
loader, and tell the other one to ignore the boot loader whenever
Next, I create a mountpoint for Mandrake and mount it:
mkdir /mandrake # to create a new mountpoint
mount -t auto /dev/hda1 /mandrake # or add an entry to /etc/fstab
Verify that you see stuff in /mandrake/boot
Now, if you're using Debian to manage this, its default lilo.conf will
probably set you up to install the boot block to a partition, rather than a
device. If you have something like
# Specifies the boot device
boot=/dev/hda3
You probably want to change it to:
# Specifies the boot device
boot=/dev/hda
(Why? I'm not sure, really. It has always worked for me the way I suggest,
while I've had problems doing it the Debian way.)
Then you'll have something like:
root=/dev/hda3
Change it to:
#root=/dev/hda3
When you get down into this bit here (whatever yours says) stick a root= in
here for this stanza:
# These images were automagically added. You may need to edit something.
image=/boot/vmlinuz-2.4.23-1-386
label="DEB 2.4.23-0"
root=/dev/hda3
initrd=/boot/initrd.img-2.4.23-1-386
read-only
Then you just add a Mandrake stanza like:
image=/mandrake/boot/vmlinuz
label="Mandrake"
root=/dev/hda1
initrd=/mandrake/boot/initrd.img
read-only
(That should probably work. Mandrake sets up and maintains symlinks
so /boot/vmlinuz->your-real-kernel and so forth.)
Then run /sbin/lilo -v to verify this worked. Remember that I haven't done
this in ages, so I may have gotten something wrong. Please forgive me if I
have. The underlying principle is that you want to use the kernel from the
Mandrake partion to install the entry for Mandrake. If you just used /boot
for both, you'd be booting Mandrake with a Debian kernel, which would break
automount and perhaps other things.
If something went wrong, you can
cp -f /etc/lilo.conf.saveass /etc/lilo.conf
/sbin/lilo -v
to get back to where you started.
