Before LBA, hard drives could encounter a 1024-cylinder limit, where the BIOS could not find a file after that point.

GRUB supports Logical Block Addressing (LBA) mode, needed to access many IDE and all SCSI hard disks. GRUB provides a true command-based, pre-OS environment on x86 machines to allow maximum flexibility in loading operating systems with certain options or gathering information about the system. GRUB contains a number of other features the most important include: GRUB supports both boot methods, allowing you to use it with almost any operating system, most popular file systems, and almost any hard disk your BIOS can recognize. With this method, the MBR points to the first sector of the partition holding the operating system, where it finds the special files necessary to actually boot that operating system. The Microsoft operating systems, as well as various other proprietary operating systems, are loaded using a chain loading boot method.

This destroys any other information stored in the MBR by other operating systems, such as Linux.

For example, Microsoft's DOS and Windows operating systems completely overwrite anything on the MBR when they are installed without incorporating any of the current MBR's configuration. The boot process used by other operating systems may differ slightly from the above, however.

This boot method is called direct loading because instructions are used to directly load the operating system, with no intermediary code between the boot-loaders and the operating system's main files (such as the kernel). Once GRUB has received the correct instructions for the operating system to start, either from its command line or configuration file, it finds the necessary boot file and hands off control of the machine to that operating system. In the default Red Hat Linux configuration, GRUB uses the settings in the MBR to display boot options in a menu. The MBR then loads the boot-loader, which takes over the process (if the boot-loader is installed in the MBR).

This MBR contains instructions on how to load the GRUB (or LILO) boot-loader, using a pre-selected operating system. Once Linux is installed on the hard drive of a system, the BIOS looks for a Master Boot Record (MBR) starting at the first sector on the first hard drive, loads its contents into memory, then passes control to it. The order of the drives used for booting is usually controlled by a particular BIOS setting on the system. Usually it checks the floppy drive (or CD-ROM drive on many newer systems) for bootable media, if present, and then it looks to the hard drive. The BIOS tests the system, looks for and checks peripherals, and then looks for a drive to use to boot the system. The BIOS provides the lowest level interface to peripheral devices and controls the first step of the boot process. The BIOS program is written into permanent read-only memory and is always available for use. When an x86 computer is booted, the processor looks at the end of the system memory for the BIOS (Basic Input/Output System) and runs it.

Both systems support dual boot installations, we refer to the HOWTOs on this subject for practical examples and background information. Should you need information about lilo, refer to the man pages and HOWTOs. We will only discuss GRUB, however, which is easier to use and more flexible. A basic understanding of this process is quite beneficial to everybody who uses a Linux system.Ī lot of Linux systems use lilo, the LInux LOader for booting operating systems. One of the most powerful aspects of Linux concerns its open method of starting and stopping the operating system, where it loads specified programs using their particular configurations, permits you to change those configurations to control the boot process, and shuts down in a graceful and organized way.īeyond the question of controlling the boot or shutdown process, the open nature of Linux makes it much easier to determine the exact source of most problems associated with starting up or shutting down your system.
