Where does LILO reside when used as the boot loader?

• A. The BIOS
• B. The kernel image
• C. The Master Boot Record (MBR)
• D. The /boot partition

Answer: (C)

LILO’s initial bootstrap is placed in the disk’s first boot sector, the Master Boot Record. When the system powers on and uses BIOS boot, the firmware reads the MBR from the boot disk and transfers control to LILO. That small piece of code in the MBR then loads the rest of LILO (the second stage) from a location on disk, typically a file in /boot, and from there it loads the kernel. The BIOS is just the hardware firmware that starts the process; the kernel image is loaded later after LILO hands off control; while /boot holds the files LILO uses, the actual initial boot code resides in the MBR.
