voilà le msg après un dolilo:

You can move /etc/conf.d/dolilo.example to /etc/conf.d/dolilo and edit it to set your preferences.
Bootsector update failed, lilo messages:
Warning: Partition 1 on /dev/hda is not marked Active.
Warning: The boot sector and map file are on different disks.
Fatal: No images have been defined.


et voilà mon fichier lilo.conf:

default=gentoo2.6.17r3       # When the timeout has passed, boot the "gentoo" section
# Only if you se framebuffer. Otherwise remove the following line:
#vga=788                   # Framebuffer setting. Adjust to your own will
