I am trying to install multiple linux distros on my computer, which also has WinXP.

My partition scheme is as follows:

/dev/hda1 --> WinXP, NTFS
/dev/hda6 --> Slackware 10.0, ext3
/dev/hda7 --> Rubyx, ext3
/dev/hda8 --> /home, ext3
/dev/hda9 --> swap

My problem is now to tell LILO to see all of my OS's. Slack was the first linux I installed, and am trying to run lilo from.

The only lines I added to lilo were:
image = /mnt/rubyx/kernel/bzImage
other = /dev/hda7
label = Rubyx
read-only

However, when I *run* lilo, I get the following error:
Added Windows *
Added Linux
Fatal: open /mnt/rubyx/kernel/bzImage: No such file or directory

/mnt/rubyx/kernel/bzImage exists, and has 755 on all directories in that path.

Any suggestions?

i can give you an alternate suggetion

copy the kernel and the boot image from your other os Rubyx into slackware's /boot with the same name.
the entries in lilo should look like this
image=/boot/vmlinuz
initrd=/boot/initrrd
root=/dev/hda7
