Explained: Boot from a scsi disk
Hi, this is a small howto for booting from a scsi disk in a system where scsi and ide disks are install. It's not that easy :-) I might setup a little Autoyast page some day, collecting all those kind of hints I figured out... When you have /dev/hda and /dev/sda in your system: 1) Set up <bootloader> <global config:type="list"> <global_entry> <key>disk</key> <value>disk=/dev/sda bios=0x80</value> </global_entry> <global_entry> <key>disk</key> <value>disk=/dev/hda bios=0x81</value> </global_entry> <global> ... </bootloader> to generate the lines disk=/dev/sda bios=0x80 disk=/dev/hda bios=0x81 in lilo.conf. 2) To make lilo install on /dev/sda instead of /dev/hda there seems to be only one way which is not yet documented: <bootloader> <loader_type>lilo</loader_type> <location>custom</location> <loader_device>/dev/sda</loader_device> </bootloader> The "custom" value for location seems to do the trick. Any other combination that seems to make sens, will fail. E.g. location = mbr loader_device = /dev/sda ends up with "boot=/dev/hda" location = / ends up with /dev/hda1, although "/" is /dev/sda1 in my system. Using global options with key=boot and value=/dev/sda is also ignored. cu, Frank -- Dipl.-Inform. Frank Steiner Web: http://www.bio.ifi.lmu.de/~steiner/ Lehrstuhl f.
