Sounds like it's already crashed and this entire discussion is academic.

Leaving a machine overnight while in the middle of such work isn't something
I'd recommend.

I don't know of any way that you can make your machine unbootable by
upgrading your lilo package to the latest version (some previous versions had
bugs) or by installing new kernel versions.
If you install a new package providing the same version of the kernel you
boot (say you install a new kernel-image-2.4.16 package to replace the
current 2.4.16 kernel you boot by default) then that could possibly result in
that kernel version not being bootable (I haven't checked the exact
functionality of kernel-package in this regard). However if you install a
new package of 2.4.16 then your 2.4.14 kernel you still have installed should
still be bootable.
