Explain LILO; what is a major advantage?

• A. It uses the smallest memory footprint.
• B. The major advantage is fast bootup of Linux when installed in the MBR.
• C. It supports graphical boot menus by default.
• D. It cannot boot other operating systems.

Answer: (B)

LILO is a simple boot loader for Linux that can reside in the Master Boot Record or in a partition’s boot sector and loads the Linux kernel image directly into memory according to a text-based configuration. The major advantage is speed when LILO is installed in the MBR. Because the MBR version is a tiny, straightforward boot stage, it hands off quickly to the kernel loader by directly loading the kernel image from disk as specified in its map, without needing extra boot stages or extensive filesystem-based loading. This keeps the initial boot flow lean and fast, giving Linux a quicker startup compared to more feature-rich, multi-stage boot loaders. LILO can boot multiple kernels and even chainload other operating systems, so it isn’t limited to a single OS. It doesn’t provide graphical boot menus by default, and its lightweight footprint is a separate characteristic rather than the primary advantage highlighted here.
