 Posted: Tue Sep 27, 2005 12:03 pm Post subject: [SOLVED] Yaboot problem |
 |
|
Hi,
I am reinstalling Gentoo, I still have Mac installed on a partition. I have problems configuring yaboot.
If I do:
yabootconfig --chroot /mnt/gentoo
I get the error:
Yabootconfig: Unable to locate bootstrap partition on /dev/hda...
Yabootconfig: You must create an 800k type: Apple_Bootstrap partition to make the disk bootable.
But I still have this partition from my previous install (it is listed by mac-fdisk -l).
If I instead try with "mkofboot -v" or "ybin -v" I get this error:
ybin: Finding OpenFirmwire device path to `/dev/hda2'...
ofpath: unable to determine sysfs mountpoint
ybin: Unable to find OpenFirmwire path for boot=/dev/hda2
ybin: Please add ofboot=<path> where <path> is the OpenFirmwire path to /dev/hda2 to /etc/yaboot.conf
ybin: Finding OpenFirmwire device path to `/dev/hda8'...
ofpath: Unable to determine sysfs mountpoint
ybin: Unable to find OpenFirmwire path for macosx=/dev/hda8
ybin: Try specifying the real OpenFirmwire for macosx=/dev/hda8 in /etc/yaboot.conf
My /etc/yaboot.conf is this
boot=/dev/hda2
#ofboot=hd:2 # I have tried uncommenting this
device=hd:
partition=4
delay=10
timeout=40
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
default=Gentoo-2.6.12-r10
defaultos=linux
image=/boot/kernel-2.6.12-gentoo-r10
label=Gentoo-2.6.12-r10
root=/dev/hda4
read-only
macosx=/dev/hda8
enablecdboot
enableofboot
I read in an old post that ofboot doesn't work when I'm chrooted.
Does anybody have an idea of what I am doing wrong?

Ok,
is your bootstrap-partition on /dev/hda2, so you can tell yabootconfig
where your bootstrap partition is.
yabootconfig -b /dev/hda2 --chroot /mnt/gentoo
But yabootconfig create a new yaboot.conf file (without overwrite) and start
mkofboot to create the filesystem and copy yaboot to the bootstrap-partition.
Good luck

When I do this it can't find my kernel:
Install yaboot bootstrap on /dev/hda2 to boot linux from /dev/hda4 [YES] y
Creating a simple /mnt/gentoo/etc/yaboot.conf...
Yabootconfig: Cannot find a kernel please locate one
Enter path to a kernel image: hd:4,/boot/kernel-2.6.12-gentoo-r10
yabootconfig: hd:4,/boot/kernel-2.6.12-gentoo-r10: No such file or directory
I have tried with other paths like "hd:4,/mnt/gentoo/boot/kernel-2.6.12-gentoo-r10" but it doesn't help. What do I do wrong? |

The mistake is in the path.
You have two possibilities:
a) I think you leave your chroot environment to start yabootconfig, like in the documentation.
So your path to the kernel ist: '/mnt/gentoo/boot/kernel-2.6.12-gentoo-r10' .
Or
b) you chroot normal and start 'mkofboot -b /dev/hda2', because you have an existing yaboot.conf file.
And it is easier, if your label in yaboot.conf is a little bit smaller, like only 'linux'

I added ofboot=/pci@f4000000/ata-6@d/disk@0:
and
changed root=/dev/hda4 to
root=/pci@f4000000/ata-6@d/disk@0:4,
and changed macosx=/dev/hda8 to
macosx=/pci@f4000000/ata-6@d/disk@0:8,
and now mkofboot -v works. When I reboot I can choose between mac, linux, cd, etc. But if I choose Mac the screen just blinks and show the same screen again. If I choose linux I get a new boot prompt where I can load one kernel (the new one from my yaboot.conf) but it gives a kernel panic:
VFS: cannot open root device "/pci...." or unknown block(0,0)
Please append a correct "root=" boot option
Kernel panic not syncing: VFS: Unable to mount root fs on unknown block(0,0)
Rebooting...
So neither Macosx or Gentoo can boot. Is it my yaboot which still is wrong or is it my kernel which is configured wrong?

I know, but I usually have more than one kernel, so this way I can distinguish them. |

Change that back to /dev/hda4

I have done that but I still got a kernel panic. Then I tried with another kernel config and now I could boot Gentoo but not Mac OS X. Then I removed all /pci@f4000000/ata-6@d/disk@0 from yaboot.conf, run ybin -v, and now both systems work.
Thanks to everyone who helped me:) |
