It was developed by Werner Almesberger and was thereafter developed by the latest developer, John Coffman. LILO is a boot manager that can boot every Operating System that is installed on the system. It is run from a hard disk but can also run from a floppy disk. It can also act as a boot loader / secondary loader.
LILO configurations in /etc/lilo.conf can be edited by any text editor on many systems. There is a configuration program, liloconfig, which will prompt for basic configuration parameters, which are written to /etc/lilo.conf.
