lilo & openbsd

socket9001 · 05-07-2004, 02:02 PM

hello,

i have one hard drive with linux & windows installed on it
and another drive with a fresh installation of openbsd.

on the first hard drive (which linux recognize as /dev/hda) i've got lilo to handle the booting.
the content of lilo.conf is:

Code:

# LILO configuration file
# generated by 'liloconfig'
#
# Start LILO global section
boot = /dev/hda
message = /boot/boot_message.txt
prompt
timeout = 200
# Override dangerous defaults that rewrite the partition table:
change-rules
  reset
 vga = normal

# End LILO global section
# DOS bootable partition config begins
other = /dev/hda1
  label = DOS
  table = /dev/hda
# DOS bootable partition config ends
# Linux bootable partition config begins
image = /vmlinuz
  root = /dev/hda3
  label = Linux
  read-only
# Linux bootable partition config ends

when i add:

Code:

# Linux bootable partition config ends
other = /dev/hdb1
  label = OpenBSD
  table = /dev/hdb

and try to update the mbr i get this error:

Code:

root@singularity:/home/socket#: lilo
Added DOS *
Added Linux
Fatal: open /dev/hdb1: No such device or address

when i set other=/dev/hdb i get this error:

Code:

root@singularity:/home/socket#: lilo
Added DOS *
Added Linux
Fatal: First sector of /dev/hdb doesn't have a valid boot signature

any idea what am i doing wrong ?

here's an output of `fdisk -l` from the linux

Code:

root@singularity:/home/socket#: fdisk -l

Socket, the easiest way of doing this I found is using the lilo GUI

Click Operatng system, click add another OS, type in the bsd location ie /dev/hdb1 and the label, click the check configuration

If everything is fine, you should get an OK sign.

If you're happy, click apply.

then as root, enter lilo, RETURN.

it should work.

lilo has a gui? do you mean liloconfig ?

MilkyBar_Kid · 05-11-2004, 01:49 PM

Yes

If you're using KDE, bring up the konsole, type lilo, RETURN

You'll get the LiLO GUI

As i've just installed OpenBSD myself recently:

for some reason my /dev/hdb drive got hdb4 assigned as the partition (i've just one, for now). i'd guess your openbsd install named it something else also.

It looks to me like you just have a disklabel for hdb and no partition table. That won't work for LILO because it needs to reference things by partition number for chainloading (like you have to do with winbloze and BSD).

If you want to coexist (multiboot) between Linux and BSD on the same box, even on different drives in the same box, it's always a good idea to do all of your partitioning with Linux fdisk. If you tag the BSD target partitions with the correct types (a6 for OpenBSD) the installer will automagically find your partition and use it.

I have several multiboot boxes and I've avoided any problems doing things as I described.

If you create a partition table and set up an a6 partition of the size you want, you can rerun the OBSD installer and it will allow you to suballocate partitions inside its slice (DOS partition).
