 Posted: Sun Dec 07, 2003 9:15 am Post subject: Trouble with configuring LILO |
 |
|
Howdy,
Well I have the kernel configured, and compiled. I've got a few other odds and ends emerged and compiled. I'm trying to create an entry in an existing lilo.conf file but it doesn't seem to be listening to me. Here's my setup:
/dev/hda1 - Formerly a WinXP partition, erased and setup with the gentoo / filesystem. I do not have a separate /boot for gentoo yet. (If this goes well, I'll probably redo things a bit.)
/dev/hda5 - Mandrake Linux 9.2 root filesystem. This is the existing system I've done everything under so far. It mounts /dev/hda1 as /home/gentoo while I've been getting everything set up.
There are other partitions, but these are the ones with kernel images.
So, my Mandrake LILO entry reads:
image=/boot/vmlinuz
label="linux"
root=/dev/hda5
initrd=/boot/initrd.img
append="quiet devfs=mount hdc=ide-scsi hdd=ide-scsi acpi=ht resume=/dev/hda6 splash=silent"
vga=788
read-only
For my Gentoo LILO entry I put in:
image=/boot/kernel-2.4.20-gentoo-r9
label="gentoo"
root=/dev/hda1
read-only
initrd=/boot/initrd-2.4.20-gentoo-r9
As far as I can tell, this ought to look at /dev/hda1 for the /boot/kernel-2.4.20-gentoo-r9 file.
At /sbin/lilo, I get this error:
Added linux *
Added linux-nonfb
Added floppy
Added old_linux
Added old_linux-nonfb
Added 2421-13
Added failsafe
Fatal: open /boot/kernel-2.4.20-gentoo-r9: No such file or directory
I'd really like to keep the kernel in /dev/hda1 with the rest of Gentoo. It looks like it's looking on /dev/hda5 (with the rest of Mandrake) for this file. Is there a way to bridge this gap?
Thanks for any help a LILO expert can provide...
Regards,
Remillard

don't forget to run lilo as root after making changes. Untill you did that lilo won't listen to the changes you made:

GRUB would be more straightforward to setup. You could just tell GRUB which partition to look in for each kernel you want to boot.
| Code: | default 0
timeout 15
title linux
root (hd0,4)
kernel /boot/vmlinuz root=/dev/hda5 quiet devfs=mount hdc=ide-scsi hdd=ide-scsi acpi=ht resume=/dev/hda6 splash=silent vga=788 <--- kernel line ends here
initrd /boot/initrd.img
title gentoo
root (hd0,0)
kernel /boot/kernel-2.4.20-gentoo-r9 root=/dev/hda1
initrd /boot/initrd-2.4.20-gentoo-r9 |

Yes, I did run /sbin/lilo after I made the changes. That's when the error of "cannot find kernel image" (or whatever it was) occurred. I haven't rebooted yet to test it as there are still errors.

This is true. In the past I have used GRUB with Mandrake. At the moment though I'm trying to make the two kernels coexist in a dual boot environment til I get all the Gentoo issues ironed out. It seems like it might be best to make LILO work as it's the current bootloader than switch to grub.
Would making a link from the /dev/hda5/boot directory to the /dev/hda1/boot directory for the simple purpose of getting lilo to find the kernel and initrd file work? Seems like it's sort of fooling it because I want /dev/hda1 to be the root and boot filesystem under gentoo, but lilo doesn't seem to recognize the "root" switch under the image line when it's reading everything.

Remillard

In that case, try this in your /etc/lilo.conf
| Code: | image=/home/gentoo/boot/kernel-2.4.20-gentoo-r9
label="gentoo"
root=/dev/hda1
read-only
initrd=/home/gentoo/boot/initrd-2.4.20-gentoo-r9 |
And make sure /home/gentoo is mounted when you run /sbin/lilo so it can find the kernel. |

If your making retrospective changes after getting your system working you must mount your root partition.
On my system my hdd is setup as
hda1 (Win XP)
hda2 (boot partition)
hda3 (swap)
hda4 (linux gentoo)
so after making changes to lilo.conf before running /sbin/lilo you have to mount the boot partition since, assuming you've followed the standard gentoo install guide (give-or-take) then your boot partition is not mounted during normal running.
in the example above i would just do a;
| Code: | | mount /dev/hda2 /boot |
then I would run
and finally
Hope That Helps alittle
