"The Linux Loader or LILO is one of the most popular methods of
booting into Linux. LILO also makes a highly flexible and
effective boot manager: handy if you have multiple operating
systems installed on your machine. This article will help you set
up and configure LILO."
"If this were the first time that you installed Linux, you
probably, would have gone the dual-boot way. But you do need a boot
manager that will allow you to switch between the different OS'
installed on your system. Linux provides LILO ( LInux LOader ).
This is a very simple but flexible boot manager. I use it to boot
multiple OS' and to check out various Linux kernels."
"When your computer starts up, the BIOS executes a bootstrap
program which lies in the Master Boot Record (MBR) of your first
hard drive or your floppy. The MBR lies on the first sector of this
device. The job of the bootstrap program is to locate and load the
operating system. If you're using Linux then this will go out at
boot and load the kernel into memory. LILO can take over this job
and also act as your boot manager."
