LILO is not deprecated, though I have used only GRUB for about 4 years
now (on most systems). Other platform versions of LILO boot other
machine architectures (SILO for Sparc comes to mind). In case you don't
know it, LILO is the default boot-loader if you use XFS for your booting
partition. XFS and grub still do not get along all that well.

It still fails to find many older OSes. Its all in the implmentaiton of
the distro. Heck, just recently the grub-installation routine for the
etch installer missed my 80GB ATA100 disk with Windows XP on it because
I replaced the splash image on it, which to be honest is a trivial thing
to do. (read as there are cheap and free programs to make it happen).

I to advise GRUB, but to forget LILO and howto use it... is treading on
dangerously thin ice there.
