Well yes I believe this is true. I followed following howto:
http://www.james.rcpt.to/programs/debian/raid1/

And I tried to load the drivers via RAM disk over mkinitrd. But my lilo
always tells me:
Fatal: map file must be on the boot RAID partition

I attached my lilo.conf and my /etc/raidtab.

Thanks for your time and help.

# This will, for instance, prevent anyone with access to the

# Note that if you really need this type of security, you will
# likely also want to use `install-mbr' to reconfigure the MBR

# removable disk or CD-ROM, then put a password on getting into the
