Sorry. The messages are lengthy, and without a running OS, I can't save
them to disk. As far as I can see, the following lines indicate problems:

Idm_validate_partition-table(): Disk read failed
Unable to read partition table
FAT: bogus logical sector size 0 (twice)
Kernel panic VFS: Unable to mount root fs on 03:06

My bootloader is LILO. I don't get as far as launching knoppix.

03:06 is hda6, which doesn't sound right if this is your knoppix install
on hdb. Change your lilo.conf (root= line) *and* run /sbin/lilo

Then run /sbin/lilo from mandrake with the knoppix's lilo.conf

The "root=" line points to /dev/hdb5, which is correct. Knoppix is booted
via a /mnt partition in Mandrake. My full lilo.conf is as follows:

boot=/dev/hda
map=/boot/map
vga=normal
default=linux
keytable=/boot/us.klt
prompt
nowarn
timeout=100
message=/boot/message
menu-scheme=wb:bw:wb:bw
ignore-table
image=/boot/vmlinuz
label=linux
root=/dev/hda7
initrd=/boot/initrd.img
append="devfs=mount hdc=ide-scsi hdd=ide-scsi"
read-only
image=/boot/vmlinuz
label=failsafe
root=/dev/hda7
initrd=/boot/initrd.img
append="failsafe devfs=nomount hdc=ide-scsi hdd=ide-scsi"
read-only
image=/mnt/knoppix/boot/vmlinuz-2.4.20-xfs
label=Knoppix
root=/dev/hdb5
read-only
# restricted
# alias=1
other=/dev/hda1
label=windows
table=/dev/hda
other=/dev/fd0
label=floppy
unsafe

Vmlinuz is of course Mandrake. There is no initrd in Knoppix. /dev/hdb5 is
/mnt/knoppix and is 96% full. Is that relevant? /dev/hdb6 is swap, but
there is plenty of space (1 GB) in /dev/hdb7, which is unused at the
moment.

Thanks Eric. To do that I will need to boot into Mandrake's Rescue mode. I
also have tomsrtbt, which is much more flexible. I used to kave it working
after a fashion with a composite lilo.conf, but had version conflicts - the
knoppix kernel wouldn't support ext3, so I couldn't save from Knoppix to
Mandrake directories (well, I could, but it seemed to wreck the directory's
fs,) and Mandrake's e2fsck was too old for knoppix. Now I have the latest
e2fsck installed, so the second problem seems fixed.

Okay.
How whas knoppix installed? Was hdb then already hdb
(and not connected as hda?)

No. partitioning etc. is irrelevant at the moment where your booting
process fails. You are sure that this lilo is installed?
ie. did you run `/sbin/lilo -v` without problems.

I reinstalled Knoppix' lilo.conf and was able to boot into Knoppix O.K., but
then I couldn't return to the original without Kernel Panic on both
distros, so I gave up and reinstalled Mandrake. And I was just waiting for
it to stabilize before making an "image" of my Mandrake system with
mkcdrec.
