/dev/hda1 - vector linux
/dev/hdb1 - slackware

lilo is installed on /dev/hda1

lilo.conf:

# Start LILO global section
boot = /dev/hda
default = linux
prompt
timeout = 1200
# Override dangerous defaults that rewrite the partition table:
change-rules
reset
bitmap = /boot/bitmap/boot.bmp
...

# Partition 1 : Slack_11.0
image = /boot/vmlinuz
root = /dev/hdb1
label = slack
append = ""
read-only

when i boot, slackware loads with vector's kernel !?
how to tell lilo that kernel is on /dev/hdb1??

From me looking at that, it only shows 1 image which is slackware. You would need something like this for both of them to work


# Start LILO global section
boot = /dev/hda
default = linux
prompt
timeout = 1200
# Override dangerous defaults that rewrite the partition table:
change-rules
reset
bitmap = /boot/bitmap/boot.bmp
...

# Partition 1 : Slack_11.0
image = /boot/vmlinuz
root = /dev/hda1
label = vector


# Partition 2 : Slack_11.0
image = /boot/vmlinuz
root = /dev/hdb1
label = slack

After you make this change and run the lilo command it should work. Do you understand?

here is other part of lilo...

# Partition 1 : Slack_11.0
image = /boot/vmlinuz
root = /dev/hdb1
label = slack
append = ""
read-only
....

....
# Partition 5: Linux
image = /boot/vmlinuz-2.6.12
root = /dev/hda1
label = linux
append = ""
read-only

This might help you figure it out.

this link solved the question...
i mounted slack partition
"mount /dev/hdb1 /mnt/slack"

and changed llilo.conf:
# Partition 2 : Slack_11.0
image = /mnt/slack/boot/vmlinuz
root = /dev/hdb1
label = slack

and then:
lilo

tux happy!
