yup. i highly recommend you look at the sample lilo.conf as well as reading the
fine manpage lilo.conf(5). basically you want to have a bunch of sections
that start like
image=/boot/vmlinuz-<version>
label=<whateveryouwanttocallit>
alias=<some key>
you can hold down shift to get a lilo prompt to select your image, or
alternately figure out how to use one of the three boot-menus that
lilo provides, also described in the manpage.

if i understand correctly the initrd image has an initial root filesystem
compiled into the kernel (or bootloader?) so that the kernel could
effectively boot up into a limited single-user mode even if / were
trashed. personally i don't use them myself, but from what i've heard
they suck if you have a kernel with a bunch of required modules because
they all have to go in the initrd as well, but otherwise don't make
that much of a difference.
