Hello, thanks for reply.

So here it is.
-----------------------------------------------------------------------------------------------

I. Config for mbr LILO of ide drive hd0 = hda:
---------------------------------------------------------------

read-only
lba32
vga=ask
boot = /dev/hda
install = /boot/boot.b
map = /boot/map
message=/boot/bootmsg.txt
prompt
timeout=100
# -------------- Image Section:
other = /dev/hdc
    label = woodyC
    alias = 4
    loader=/boot/chain.b
    map-drive = 0x80
        to = 0x83

image = /boot/vmlinuz
    label = kiste-2.19  # an old  SuSe i have to wipe out ... 
    alias = 1
    root = /dev/hda6

image = /boot/vmlinuz
    label = potato-2.19         # my first Debian; now my rescue system ;-)
    alias = 2
    root = /dev/hdc11    

image = /boot/vmlinuz
    label = woody-2.19          # But usually i let it chain by timeout (image 
0). 
    alias = 3
    root = /dev/hdc6

II. Config for mbr LILO of ide drive hd1 = hdc:
---------------------------------------------------------------

lba32
boot=/dev/hdc
install=/boot/boot-menu.b
map=/boot/map
delay=400
message=/boot/bootmsg.txt
prompt
timeout=200
vga=0

image=/boot/vmlinuz             # this one doesn't wotk with grub from floppy.
        label=Woody
        root=/dev/hdc6
        read-only
        alias=1

image=/boot/POTATO/vmlinuz
        label=Potato
        read-only
        root=/dev/hdc11
        optional
        alias=2

other=/dev/hda
        label=boot_hda
        alias=3
        loader=/boot/chain.b
        map-drive = 0x83                # didn't get it working with lilo.
        to = 0x80

In a few days, i go pick it up with Kernel 2.4.18 and 2.4.20.
If i get the same with 4.18 i'll try to file a bug report.
Thank you for the hint.
