The LILO boot loader is installed in one of two places: either the Master Boot Record (MBR) of the disk device or the boot sector of the partition device in which ttylinux is being installed.
With LILO installed in the MBR of the first disk, it will completely take over the entire boot process of the computer. If there are other operating systems installed on the computer they need to be specified in the LILO configuration file, /etc/lilo.conf, in order to boot them.
With LILO installed in the boot sector of the target partition or in the MBR of a disk other than the first one in your computer, the bootloader installed in the MBR of the first disk needs to be configured to boot the ttylinux target partition.
