By default, the boot loader GRUB is used in SUSE Linux. However, in some cases and for special hardware and software constellations, LILO may be more suitable. If you update from an older SUSE Linux version that uses LILO, LILO is installed.
Information about the installation and configuration of LILO is available
in the Support Database under the keyword LILO and in
/usr/share/doc/packages/lilo.
