LIL Error When Booting..What Do I Try Next?

Lucinda · 05-26-2004, 06:32 PM

I upgraded to Slack Current a few days ago and everything was going well. I haven't made any changes to my system files since then and didn't install any new software yesterday. This morning I tried to boot my machine and got the error message "LIL" when trying to load LILO. I have LILO on my MBR and I don't run any other OS except linux.

The explanation for the LIL error is:

" LIL The second stage boot loader has been started, but it can't load the descriptor table from the map file. This is typically caused by a media failure or by a geometry mismatch."

I couldn't boot with the cd I made from "makerescue" but I was able to boot with a Slax live cd. This morning I could get into the system fine after booting (via root=/dev/hda3), but noticed that once I was in, my hard drive was being recognized as /dev/ide/host0/bus0/target0/lun0/ instead of hda3!! Other than that, I could operate as "root" on /hd3. When I rebooted this evening, I wasn't able to do that anymore. I can't access "root=/dev/hd3" at boot time. The message I get back is that the kernel isn't available on that partition. Nor is it available on /dev/ide/host0/bus0/target0/lun0/part3.

I added a linear option to my lilo.conf file, but that didn't work. I couldn't run /sbin/lilo from my position as "root" on the Slax live cd because I didn't have proper permissions to the files on my hard drive (how can I change this??)

This is from my lilo.conf file:

# LILO configuration file

When I boot with the Slax live disk, my hda drive is no longer recognized. Instead, it becomes /dev/ide/host0/bus0/target0/lun0/. When I run /part3/sbin/lilo -v -v from that drive I get:

(The last "fatal" error is due to me running the program as "root" on the Slax live cd and not as root on hda3).

The output I get from running fdisk -l as "root" on the Slax live cd is :

I tried to run /sbin/lilo -v -v -v >/boot/lilo.log 2>/boot/lilo.logerr from dev/ide/host0/bus0/target0/lun0/part3, but it didn't work because I didn't have permission to write to the /boot directory and I was unable to change this permission while logged on as "root" on the Slax live cd. Is there some way that I can become root on / on my hard drive so that I can change permissions to allow me access to files and directories?

I entered the bios settings on my Dell Dimension 4500, but I didn't see any information about the hard drive, so I can't tell if there is a geometry mismatch or not.

I also have an external hard drive and CF card reader that the Slax live cd also recognizes.

Any idea what I can try next? Fortunately, I have my system backed up to my external hard drive. What else can try other than a complete reinstall? What could suddenly be causing this error?

Thanks,
Lucinda

You can run lilo from a knoppix cd using chroot. Boot up with knoppix and open a console and run:

$ su
<Enter>
# mount /dev/hda3 /mnt/hda3
# chroot /mnt/hda3
# /sbin/lilo -v

I'm not sure about the slax live cd but in knoppix all the partitions are mounted "nodev" and as a result, lilo will not run; you get a permission denied error even as root and it won't allow you to do chroot IIRC. Using the mount command per the above fixes that in knoppix(i.e. including the "/dev/hdxx" with the mount point in the mount command) and lilo will run and write to your mbr.

Here's where I'm at today, following up with my post from yesterday.

I haven't been able to get makebootdisk to make a proper LILO boot disk for me (maybe the files are too big?), but I managed to find an old Syslink boot disk that I could boot with. I used this to get into my system and create a new Syslink boot disk with my new kernel. I can boot up my system NO PROBLEM with the Syslink boot disk. Everything looks and functions as it should. But I don't want to be relegated to booting off a floppy for the rest of my life...

So it looks like my hard drive itself is fine.

I then tried this:
lilo -u /dev/hda

followed by lilo and rebooted, but I had no luck.

I then used "hdparm" to see how linux sees my hard drive and got these results:
hdparm -g /dev/hda

/dev/hda:
geometry = 4866/255/63, sectors = 78177792, start = 0

So it is seeing 4866 cylinders, 255 heads and 63 sectors.

I then ran "/sbin/lilo -v -v -v >/boot/lilo.log 2>/boot/lilo.logerr" and got nothing back in the .logerr file (good) and the .log file produced this for lilo:

which seems to indicate that lilo is seeing the same hard drive
geometry as linux (i.e. 4866/255/63).

I didn't see any obvious errors in dmesg after booting with the

*********************************************************

I have to admit, I don't know how to interpret the dmesg results. Any obvious problems there?

And I did add LBA32 to my lilo.conf which is supposed to allow lilo to bypass any cylinder limits on the hard drive, but that didn't work either.

I don't understand why lilo doesn't like the hard drive. Like I've said, it's worked fine, I made no changes to lilo and then suddenly the "LIL"... message popped up. Maybe I should consider using a new loader (i.e. GRUB?). Or will doing something with "udev" help?

Thanks for your help,
Lucinda
