I have SuSE 6.4 installed on hda using ext2 file system. I've just installed
Slackware on hdb and made a floppy to boot it. It's working fine so I want to
add it as an option on Lilo. The Slackware uses ext3 and when I try to copy
boot details from the floppy I get the message that the kernel can't deal with
ext3 fs. Is there a way around this ? TIA
Ken.

Yep just make sure that the kernels on both systems support ext3 and then
rerun lilo.

Um....make the kernel handle ext3?
perhaps I'm not understanding the question correctly...
do you know how to make a custom kernel, and do you think that would solve
the problem?

There are really two issues here

The first is wether or not you want to be able to access the Slack
partitions from SuSE. If you do then you will need to recompile
your SuSE kernel (http://www.volutin.net/linux.html follow the link).

The second is actually making lilo boot the Slack install.
Dont copy the boot options from the floppy just make the lilo entry
manually....
Ive assumed the following about your Slack install
root = /dev/hdb2
kernel is located in the SuSE boot partition as vmlinuz-slackware

# Lilo.conf, the boot config file.
#
lba32 # allow lba access
boot=/dev/hda #install in primaries MBR
install=/boot/boot.b
map=/boot/map
delay=20 # milliseconds to wait for choice
vga=normal
default=SuSE # the default image to boot

image=/boot/vmlinuz-suse
label=SuSE
root=/dev/hda2
read-only

image=/boot/vmlinuz-slackware
label=Slack
root=/dev/hdb2
read-only

#
# End Lilo.conf

Alternatively you could install the Slack boot loader into /dev/hdb
and then just pass control to it in the lilo.conf file, but this is
slightly inefficient because you load two boot loaders.

AFAIK, ext3 is backwards compatible to ext2. So instead of mounting your ext3
partition as ext3 in Suse, mount it as ext2.

Thank you all for the responses. I wanted to avoid fiddling with my SuSE
kernel (coward) so Joe's approach appeals. But one day...........
Ken.
