till today I had:
slackware 10.2 on hda2 (reiser)
win on hda3

my lilo.con was:
------------------------------------------------------------
# cat /etc/lilo.conf
# LILO configuration file
# generated by 'liloconfig'
#
# Start LILO global section
boot="/dev/hda"
#compact # faster, but won't work on all systems.
prompt
timeout="300"
# Normal VGA console
vga="773"
# Linux bootable partition config begins

image="/boot/vmlinuz"
root="/dev/hda2"
label="Linux_Slackware"
read-only # Non-UMSDOS filesystems should be mounted read-only for checking
# Linux bootable partition config ends
# Windows bootable partition config begins

other = /dev/hda3
label = Window_XP_SP2
table = /dev/hda
# Windows bootable partition config ends
----------------------------------------------------------------

everithing was perfect till I installed today fedora core on my other hard disk [/dev/hdc1](ext3) without bootloader option

Now i don't know how to configure lilo to be able boot fedora too

I've tried:
----
mount /dev/hdc1 /mnt/tmp
ls /mnt/tmp/boot/
grub
System.map-2.6.18-1.2798.fc6xen
symvers-2.6.18-1.2798.fc6xen.gz
xen-syms-2.6.18-1.2798.fc6
config-2.6.18-1.2798.fc6xen
initrd-2.6.18-1.2798.fc6xen.img
vmlinuz-2.6.18-1.2798.fc6xen
xen.gz-2.6.18-1.2798.fc6

added to my lilo.conf ->
-----------------
image=/mnt/tmp/boot/vmlinuz-2.6.18-1.2798.fc6xen
label="FC6"
root=/dev/hdc1
initrd=/mnt/tmp/boot/initrd-2.6.18-1.2798.fc6xen.img
read-only
-----------------

/sbin/lilo

Fatal: Setup length exceeds 31 maximum; kernel setup will overwrite boot loader

with this commented #initrd=/mnt/tmp/boot/initrd-2.6.18-1.2798.fc6xen.img
the same error apears.

PLS SOMEONE HELP!

Try this as your lilo.conf:
Once you've saved that, run the following command (still as root):
That should do the trick

other = /dev/hdc1
label = "Fedora Core 6"
table = /dev/hdc

Fatal: First sector of /dev/hdc1 doesn't have a valid boot signature

Hmm... Are you sure /dev/hdc1 is the FC6's / partition?

According to your mount command in the first post it is, but for some reason LILO isn't recognising it as such... :/

100% I instaled on hdc1 .. and like u said I mounted without a problem it. and listed /boot directory with fc6 files.

so .. no lilo guru here? :P

I found this on fedora wiki but is or grub , some ideeas how it will be for lilo???

I have Fedora and Slack dual booting using grub since that is the FC boot loader. Just add Slack's info to grub.conf on the Fedora partition and hash out the hiddenmenu entry (#hiddenmenu).

Your lilo entry for Slack:

image="/boot/vmlinuz"
root="/dev/hda2"
label="Linux_Slackware"
read-only

Changes to this in GRUB:

title Slackware
root (hd0,1)
kernel /boot/vmlinuz ro

I think (I'm not at my Slack box to check). Here's a good post from the Fedora forum:

http://forums.fedoraforum.org/forum/...conf+lilo.conf

Also, setup Fedora to boot using GRUB. You can use the first FC install cd or DVD for this. Let me know if you have problems and I'll send you more info from my Fedora/Slack box.

thank you ppl for all your feedback ..
I solved the problem, not very beautiful solution but it's work (since fedora is on test on my pc )

The solution I found:
I installed fedora's grub on hard-disk with fedora [not mbr!](/dev/hdc in my case)
Then I added to my lilo.conf:

other = /dev/hdc1
label = "Fedora's GRUB"
table = /dev/hdc

# /sbin/lilo

and it's works perfect (2 bootloaders untill I load fedora, but it's ok for me.)
