[newbie] kernel update

[Lance Borden]

Hey, I've been following the thread about updating the kernel, and would like
to update the kernel on my system, but y'all haven't mentioned anything about
the LILO in the emails.  Once you install a new kernel, don't you have to go in
and change a setting somewhere so that the machine will boot the new kernel
instead of the old one?  And, which file is that that needs to be changed? 
Thanks for the help!
