Subject: Boot Problems
Craig,

Thank you for your help. The lilo.conf file was set with the right boot and
I ran lilo with the -v and now the system boots from the hard drive. I have
no idea why the -v would make the difference but it must have. This system
is my internal router and it does not seem to be routing. So I ran
iptables -L to see if the iptables were setup right. This is the output I
get:

There seems to be many errors in this output. What would cause these errors
and how do I fix them?

you're obviously gonna have to use the rescue disk again...pay attention
to which partition the / is on (/dev/hda?)

edit /etc/lilo.conf to reflect that (been a while since I used lilo)

then run lilo again...make sure that when you run lilo, you specify
verbose so if it fails to verify something like the location of the root
volume...you don't have to reboot to find out.

e.g.
lilo -v
