LILO - Keytable read/checksum error on bootup

I've searched high and low for a solution, apparently my new installation of Slackware 10.2 is fubar.

I'm hoping that someone has run into this problem before, and can help with the issue at hand.

Here's my fstab:
/dev/hda2 swap swap defaults 0 0
/dev/hda1 / ext2 defaults 1 1
/dev/hda3 /var/www/htdocs ext2 defaults 1 2
/dev/hda4 /devel ext2 defaults 1 2
/dev/cdrom /mnt/cdrom auto noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0
/dev/hda1 is bootable in the partition table

Here's my lilo.conf:
# LILO configuration file
# generated by 'liloconfig'
# Start LILO global section
boot = /dev/hda
#compact # faster, but won't work on all systems.
timeout = 50
# Normal VGA console
vga = normal

image = /boot/vmlinuz
root = /dev/hda1
label = Linux
read-only # Non-UMSDOS filesystems should be mounted read-only for checking
# Linux bootable partition config ends
Here's the result of lilo -v:
root@saevenstar:~# lilo -v

Help appreciated, and direly needed!

From the body of your post, I don't see a problem. I believe the comment about boot.0300 is advisory and not fatal.

Should I gather from your title that it then refuses to boot with a Keytable read/checksum error? I've not had that problem, but I suspect the data on the disk just got garbled somehow. I would run fsck (force it with -f) on the partition containing /boot and re-run LILO to see if it straightens out.

Here's a way to proceed if you can't boot your existing system:
  1. Boot from your install disk in rescue mode (if it has one) or from a live CD.
  2. Run fsck -f on the partition containing /boot.
  3. Mount your / partition, and if you have a seperate /boot partition mount it on the / partition at its normal place. Make sure you mount the root partition with the dev option.
  4. Run chroot /mnt/hda1 LILO. Change /mnt/hda1 to the mount point of /.
  5. Unmount your partitions
  6. Reboot and hope for the best
If it fails again, I would wonder if you have a hard drive problem.

Good luck.

Thanks for the post.. I'd tried all these tactics unfortunately. I'd run into 9A and 99 errors, and on the same train as yourself, decided to give Grub (which I had on a Ubuntu CD) a try. In fact, I have to admit I was distraught by Slack and installed Ubuntu-server entirely. After a stress-free 30-minute install, I had a full SMP kernel running that booted properly. I can't explain it - broken LILO in new Slack? Abandoned old drives? No clue. Both the MBA, and EXT methods failed using the packaged Lilo.

Thanks for the shot, I'll stick with Ubuntu for now, it's actually pretty negligible of a speed difference with this latest 6.06 release.

Try removing compact


I just ran into the same problem.
What I found is that I only have this problem if my lilo.conf
doesn't contain the compact line.

Try adding that, i.e. uncomment it.
