Booting the wrong Kernel - Knoppix, Slackware, LiLo

[thejackal13]

I am using a knoppix distro for a roboitcs project and it came on a live cd. I have a laptop that boots windows, slackware, and know knoppix using lilo. I managed to boot the knoppix distro almost perfectly but it is booting the wrong kernel somehow. In slackware I am using a 2.4 kernel and the knoppix distro is suppose to be running the 2.6 kernel. When i use the live cd it boots the 2.6 kernel correctly off the cd. When i boot the knoppix off the HD now it boots the 2.4 kernel and loads the OS. The OS is functional and I haven't noticed any problems but can someone help me boot the correct kernel. My boot parition is stored on the mbr. My lilo config looks like:

#Linux
image = /boot/vmlinuz
root = /dev/hdc7
label = linux
read-only

#knoppix
image =/boot/vmlinuz
root = /dev/hdc8
label = knoppix
read-only

the lilo that i am using is part of the slack distro not the knoppix distro. and in my fstab i am not even mounting the hdc7 parition at all.

any ideas?

If I read this correctly, you have knoppix installed on /dev/hdc8. Right?
Try this: boot knoppix from the CD then run this code in a root terminal window:

( set -x
uname -va
cat /etc/knoppix-version
cat /proc/partitions
mount /mnt/hdc8
ls -a /mnt/hdc8/
) >& post.txt

I see you are using vmlinuz.

My guess is that is the vmlinuz file. It's pointing to the 2.4 kernel. The default vmlinuz does that.

You need to make an new Vmlinuz file that points to the 2.6 kernel.

If you look carefully at the distro, you see that vmlinuz is actually a link that points to 2.4.

That's what you need to change.

sorry for the delayed reply, i just got caught up with some other linux stuff and then i couldn't get back to this laptop for a day here is that post.txt

the symbolic link in the boot folder is pointing to the 2.6 kernel, plus the 2.4 kernel is on a whole nother partition

Interesting. Did you use this CD to install Knoppix to /dev/hdc8? If so, this is puzzling. 3.8.2 doesn't even have a 2.4 kernel.

After you modified lilo.conf in Slack, did you rerun lilo?

Lastly, can you boot into the installed knoppix (the one on /dev/hdc8/) and run these commands:

( set -x
uname -va
cat /etc/knoppix-version
cat /proc/partitions
df -HTl
ls -la /boot/
) >& post.txt

Yes, you are running the 2.4 kernel.

Because of a couple of typos, I was wondering if you could rerun these commands:

( set -x
cat /etc/knoppix-version
df -HT
) >& post.txt

Please post the output of post.txt.

Admittedly, I haven't used lilo in quite a while, but I'm suspecting that lilo is "pointing to the wrong place." I'll have to read up on lilo again to be sure.

thanks, sorry for the typo's, i will post when i get home this evening

speaking of lilo. my lilo is on the mbr, and it is configured in the slackware partition, haven't touched anything with lilo on the knoppix partition.

Sounds good.

speaking of lilo. my lilo is on the mbr, and it is configured in the slackware partition, haven't touched anything with lilo on the knoppix partition.

As I said, I haven't played with lilo in a while. So, I'm just wondering what would happen if you boot into Slackware and change your boot stanza for Knoppix to this:

#knoppix
image =/boot/vmlinuz-2.6.11 
root = /dev/hdc8
label = knoppix
read-only

After all, vmlinuz on /dev/hdc8 is just a soft link to vmlinuz-2.6.11. If you make the change to lilo.conf, rerun lilo, and reboot, can you then have Knoppix boot the 2.6.11 kernel? If not, I'm curious to know what error you get.
