That makes sense.  The authors probably included this note in the 
instructions on the assumption that this would be a dual-boot system. 
Every single page of instructions I've found EVERYWHERE on how to set up 
a boot loader assumes a dual-boot system.  Kind of frustrating in a way, 
since this computer has no Windows on it at all.

Actually, it looks to me like LuMiX is based on RedHat instead of on 
Debian like I had originally assumed.  It uses GRUB as its boot loader 
instead of LILO.  Either way, a boot loader still has to be installed.  :)

LuMiX, by the way, is a Linux distribution developed exclusively for 
public libraries.  Our librarian was interested in trying it out; and 
since I'm on the library commission and the only one in the library who 
has any experience with Linux (our IT guy is a good fellow but he's a 
die-hard M$ loyalist), I volunteered to install it onto one of the 
desktop machines that we retired.

I'll try them all, and let you know.  Thanks!
