[SOLVED] Adding a new system to the Slackware LILO boot loader & Please help me!

Forget-Me-Not · 11-04-2012, 12:20 AM

I used Slackware 13.37 to install LFS in partition sda2 # ext3

My friend told me that:
"After you finish LFS you have an extra OS, which is completely independent from your host"

I need to boot into LFS.

I mean "Adding a new system to the Slackware LILO boot loader"

Thank you very much!

If you read /etc/lilo.conf you can figure out what to put there. Eg

Code:

image = /path/to/lfs/kernel
    initrd = /path/to/lfs/initrd
    root = /dev/sda2 # your lfs root partition
    label = <whatever you like to identify it>
    read-only

Also see man lilo.conf for more lilo options and tweaks.

There are 2 paths

In LFS environment
root:/boot# ls
config-3.5.2 System.map-3.5.2 vmlinuz-3.5.2-lfs-7.2

In Slackware
root@localhost:/boot# ls
README.initrd@ config@ slack.bmp
System.map@ config-generic-2.6.37.6 vmlinuz@
System.map-generic-2.6.37.6 config-generic-smp-2.6.37.6-smp vmlinuz-generic-2.6.37.6
System.map-generic-smp-2.6.37.6-smp config-huge-2.6.37.6 vmlinuz-generic-smp-2.6.37.6-smp
System.map-huge-2.6.37.6 config-huge-smp-2.6.37.6-smp vmlinuz-huge-2.6.37.6
System.map-huge-smp-2.6.37.6-smp diag1.img vmlinuz-huge-smp-2.6.37.6-smp
boot.0800 diag2.img
boot_message.txt map

I read on some documentations

Quote:

modify lilo.conf to point to the image

First, I cd over to /boot:

System.map chain.b module-info-2.2.16-3ext3
System.map-2.2.16-3 initrd-2.2.16-3.img vmlinux-2.2.16-3
System.map-2.2.16-3ext3 vmlinux-2.2.16-3ext3
vmlinuz kernel.h
boot.b map vmlinuz-2.2.16-3
module-info vmlinuz-2.2.16-3ext3 module-info-2.2.16-3

Here you can see that I have a 2.2.16-3 kernel and I have added a second kernel with ext3 support (vmlinuz-2.2.16-3ext3)

http://surfer.nmr.mgh.harvard.edu/pa...n/ramdisk.html

I don't know how to added a second kernel.
Hope you show me! Thank you very much!

Boot slackware, mount your lfs partition on /mnt edit the /etc/lilo.conf and add the following

Quote:

image = /mnt/boot/vmlinux-2.2.16-3ext3
root = /dev/sda2 # your lfs root partition
label = <whatever you like to identify it>
read-only

rerun lilo

Forget-Me-Not · 11-04-2012, 09:05 AM

This is my kernel vmlinuz-3.5.2-lfs-7.2 !

Please help me!

Why don't you read either Slackware documentation or the LFS one instead of some outdated ones. The reference you used is from 2001. It will not work soon or later. Have you read what segmentation_fault suggested. Check the lilo conf section here http://docs.slackware.com/slackbook:...91;]=lilo#lilo

Fix your lilo.conf file, run lilo. If you have errors when running lilo, post back here with your lilo.conf

Forget-Me-Not · 11-04-2012, 10:27 AM

Attached file is my lilo.conf which was modified.
After modification, I pressed <Ctrl> O.
This is the first time I use nano. Thus I opened new Konsole and run lilo
The result
I couldn't add lfs. It's still old kernel.

For your /etc/lilo.conf to work like it is you will have to copy the lfs kernel to Slackwares /boot then rerun lilo.

Forget-Me-Not · 11-05-2012, 01:44 AM

I copied 3 files
config-3.5.2 System.map-3.5.2 vmlinuz-3.5.2-lfs-7.2

to directory
root@localhost:/boot

It would be

Quote:

README.initrd@ config@ slack.bmp
System.map@ config-generic-2.6.37.6 vmlinuz@
System.map-generic-2.6.37.6 config-generic-smp-2.6.37.6-smp vmlinuz-generic-2.6.37.6
System.map-generic-smp-2.6.37.6-smp config-huge-2.6.37.6 vmlinuz-generic-smp-2.6.37.6-smp
System.map-huge-2.6.37.6 config-huge-smp-2.6.37.6-smp vmlinuz-huge-2.6.37.6
System.map-huge-smp-2.6.37.6-smp diag1.img vmlinuz-huge-smp-2.6.37.6-smp
boot.0800 diag2.img
boot_message.txt map
config-3.5.2 System.map-3.5.2 vmlinuz-3.5.2-lfs-7.2

run lilo -v
The result's okey. Added lfs *

Then I executed command-lines as following:
a)http://www.linuxfromscratch.org/lfs/...09/theend.html

b)http://www.linuxfromscratch.org/lfs/...09/reboot.html

Finally I rebooted computer. And the output is not as expectation. I kept it in attached file.

Might you help me? Thank you very much!

looks like your kernel is missing some drivers to boot correctly and/or you need to create an initrd. If you make an initrd you will need to copy it to the slackwares /boot and rerun lilo.

Hi,

After I added

initrd = /boot/initrd

It look like more optimistic than the first. However it's still a my bug. Did you see it before which I kept it in attached file?
This one took me a long time. Hope me will receive your help to complete it! Thank you so much!

See you tomorrow. Good night!

colorpurple21859 · 11-06-2012, 10:18 PM

add this line to the lfs entry

Code:

append = "root=/dev/sda?"

and rerun lilo. ? is your lfs partition number

Forget-Me-Not · 11-08-2012, 06:00 PM

Sorry!It still doesn't work!

markush · 11-09-2012, 09:08 AM

Hello,

I'd like to see the output of

Code:

fdisk -l

and

Code:

df -h

when Slackware is running. I would suggest to do the following, compile lilo for your LFS and install it, then configure it to install on the superblock of the partition where your LFS-boot directory is (where the kernel resides) and let this chainload from Slackware's lilo. This means to have lilo installed on both, Slackware and LFS. (that's what I would do).

Markus

BTW: maybe you'd be better off if you use Slackware for some month and get some experience with it. Then you're ready for LFS.
