Thanks for your help.  My big confusion was the menu *before* the actual 
elilo label list.  I was trying to find some way to add a menu option, but 
it turns out that initial menu doesn't even matter.  I hit enter at the 
menu on the "Red Hat Linux" option and was then was taken to the ELILO: 
prompt, which my new entry in elilo.conf was available.  That's all I 
needed.

Thanks!
