LILO – This tutorial uses the last available version, v24.2.īecause LILO is no longer under active development, only a handful of Linux distributions still have it installed or in standard repositories.A Linux system (physical or virtual) capable of running LILO.Before you expect the below demos to work on your system, be sure you have the following: The demos in this section will only work under a few pre-defined conditions.

Let’s now get more hands-on with LILO by learning how to access the LILO configuration and change some standard settings that you might need in the real world.
To demonstrate LILO, this tutorial will use Slackware, where LILO comes preinstalled. To troubleshoot or configure LILO Linux bootloader on legacy systems well, you must first understand how it works at a high level. Understanding How the LILO Linux Bootloader Works The INIT System or SystemD is a process that ensures that all the scripts and dependencies of a particular run level are started in the correct order the system can go into one of various modes (run levels). After the kernel loads, the process then passes control to the INIT system, mainly Systemd.Ĥ. The bootloader itself or via a menu allows you to select what kernel Linux loads, perhaps in a dual-booting scenario. The bootloader (LILO or perhaps GRUB) then contains instructions on where Linux can find the appropriate kernel to load. Most bootloaders contain just enough instruction to call subsequent stages if the system is set up with an MBR.ģ. The POST process uses a section of the boot disk to look for how to boot the operating system known as the bootloader.
Once all tests pass, the boot process looks for a special section on the boot disk. The Power On Self Test (POST) – This stage performs a short test on all connected hardware.
