OK, if I get you right what you want is to be able to use lilo, off a
floppy so that you will have a boot prompt in order to pass options to
your scsi drive. The rest of the partitions are using a different boot
loader. I'm also assuming you don't really need to boot the kernel off
the floppy but off your HD will be fine. Basically all you need to do
is run lilo off a floppy. In order to do that -
1) Stick a floppy in your "A" drive and -
# superformat /dev/fd0 (just to make sure)
2) # cp /etc/lilo.conf /etc/lilo.floppy
This is if you have one. If you don't you will have to create one.
3) Modify /etc/lilo.floppy for your current needs.
Something like this -
boot=/dev/fd0
map=/mnt/floppy/map
install=/mnt/floppy/boot.b
append="mem=127M"
ramdisk=8192
prompt
timeout=40
default=deb
vga=4
image=/vmlinuz
label=linux
read-only
root=/dev/hda12
4) # mount /dev/fd0 /mnt/floppy
5) # cp /boot/boot.b /mnt/floppy
# cp /boot/map /mnt/floppy (works without but it must be there for
some reason)
# cp /boot/initrd.version /mnt/floppy (if you have one)
6) Install lilo on the floppy -
# lilo -C /etc/lilo.floppy
If Debian is below the 1024 cut off on a large drive add the line -
lba32
in /etc/lilo.floppy or run the following command -
# lilo -C /etc/lilo.floppy -L
7) Leave the floppy in and test.
That should do it. Of course you will have to tweak lilo.floppy so they work
for your drive. You could set it up to boot both slink and potato on
the drive in question as well as windows, etc.
