LILO is a boot loader for Linux. LILO stands for Linux Loader that is used to load Linux into memory. It is used mainly to load the Linux operating system into main memory so as to begin operation. Lilo handles some tasks such as locating the kernel, identifying other supporting programs, load memory and starts the kernel. The configuration file of lilo is located at “/etc/lilo.conf”. Lilo reads this configuration file and it tells Lilo where to place the bootloader.
