Serial Console

Hi,
	The only thing that I can see that is missing from all of the replies 
that might affect you with Redhat 7.3 is the "boot message."  In 
lilo.conf, there is a line "message=/boot/message" that causes a 
graphical kernel selector to appear (instead of the "boot:" prompt).  It 
says "Press Ctrl-x for text mode".  I was unable to get to "text mode" 
(the "boot:" prompt) by pressing Ctrl-x from my serial console (nor 
could I see the graphical selector) and, as a result, could not select 
the kernel or specify kernel parameters.  Although I don't plan on 
selecting different kernels or specifying kernel parameters very often, 
I might want to do this to get to single-user mode, for example.  If you 
run into this, you can get rid of the graphical kernel selector by 
commenting out the "message=/boot/message" line in /etc/lilo.conf (and 
rerunning lilo of course).
