Yes, that's the complicated marriage between the traditional BSD-disk-
slice concept and the traditional MS-DOS partitioning scheme. I won't
say that i understand that completely, nor that i like it completely,
but if it will boot at all, it will boot thru lilo as well.

Phiuuui! I see. It might be, in general, a good idea to put at least
the root partition of any bootable OS on the first or second disk.

Still that? I did an upgrade to FreeBSD 2.1-STABLE some time ago, and
it looked like it could now. At least i was able to dump the extended
(linux) partitions from FreeBSD. But i didn't look at that more closely.

Yes, thats that. Maybe this can be avoided when controlling the FreeBSD
disklabel program manually, but that was too complicated for me to find
out how (and i tried it quite a lot of times). So i wouldn't suggest that,
there seems to be good chance to make it worse by such experimenting.

As we say in German: Erst die Arbeit, dann das Vergnuegen.;-)
(First the labour, then the fun.)
Enjoy!
