Booting and Boot Managers
Note
Boot Loader Selection
If you update from a previous version of SUSE LINUX in which
LILO was the boot manager, the new system continues to use
LILO. If you install SUSE LINUX from scratch, the system uses
GRUB unless the root partition is installed on a RAID system of
the following types:
CPU-controlled RAID controllers, such as many Promise and
Highpoint controllers
Software RAID
LVM
For information about the installation of LILO, search for the
keyword “LILO” in the Support Database (http://portal.
suse.de/sdb/en/index.html).
Note
8.4 Booting with GRUB
GRUB (Grand Unified Bootloader) consists of two stages. The first stage is
only 512 bytes long. It is written to the MBR or to the boot sector of a disk
partition or floppy disk. The second, larger stage is loaded after that and
holds the program code. The only purpose of the first stage is to load the
second one.
The second stage contains code for reading file systems. Currently sup-
ported are Ext2, Ext3, ReiserFS, JFS, XFS, Minix, and the DOS FAT file sys-
tem used by Windows. GRUB has the ability to access file systems even be-
fore booting is finished, as long as they are on devices handled by the BIOS
(floppies or hard disks).
Note
GRUB and JFS
Although technically possible, a combination of GRUB with JFS
is not recommended.
