 Posted: Tue Aug 06, 2013 7:14 pm Post subject: [Solved] First boot failure - Yaboot problems |
 |
|
hi,
I am installing a gentoo on an Imac G5(alsa-nocam) by a live cd with the help of gentoo handbook-ppc, and i'm blocked on the part 10.... configuring yaboot.
yaboot crash on the startup : Unknown or corrupt filesystem
i had already installed an ubuntu and a Mint before and the dual boot between those both installations worked perfectly before.
i found on the forum this post : https://forums.gentoo.org/viewtopic-p-7104900.html where they advice to downgrade yaboot & e2fsprogs ... this not works for me.
An other one, advice to boot on an ext3 partition so I ceated an other ext3 partition.
I fear that my partition table is broken or anything else cause i can't boot on my ubuntu part...
mac-fdisk :
| Code: |
/dev/sda
# type name length base ( size ) system
/dev/sda1 Apple_partition_map Apple 63 @ 1 ( 31.5k) Partition map
/dev/sda2 Apple_Bootstrap untitled 1954 @ 42460072 (977.0k) NewWorld bootblock
/dev/sda3 Apple_HFS Apple_HFS_Untitled_ 1 42197864 @ 262208 ( 20.1G) HFS # MacosX 10.4

/dev/sda5 Apple_HFS Apple_HFS_Untitled_2 121804944 @ 156422000 ( 58.1G) HFS # MacosX 10.5

yaboot.conf
i'm a beginner but the option "partition=X" must link to the partition like /dev/sdX or must follow the physical place on the blocks ??
i followed some posts, so the yaboot.conf may be poluted
| Code: |
ofboot=hd:2
macosx=/dev/sda5
boot=/dev/sda2
device=hd:
partition=2
timeout=30
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
enablecdboot
enableofboot
image=/dev/sda9/boot/vmlinux
label=gentoo
read-only
root=/dev/sda7
partition=7
image=hd:4,/boot/vmlinux
label=ubuntu
read-only
root=/dev/sda4
partition=4
|
some ideas guys ???
Edit 16 1ug 2013 :
my problem was solved by restarting the install from scratch (removed all my datas & partitions (ubuntu&osX)). it's not a clean solution but it work.... (not very proud  )

What live-cd? You've got the base-system installed on hd and work with a chroot-environment?
sys-boot/yaboot-static-1.3.16-r1 works - don't_t use 1.3.17

You haven't got a copy of their yaboot.conf?
If you install ppc64 (~ppc64), what you probably should, you need to use sysboot/yaboot-static-1.3.16-r1
I boot from an ext4 partition, but it depends on the kernel you use - it has to be configured for this and shouldn't be too old either ;-)

The boot partition behind Apple_Free looks strange to me and you don't realy need one in this case. Keep it simple for now.
This is my yaboot.conf (without my extra kernels and partitions and without an entry for nouveau)
| Code: | boot=/dev/sdb2
device=/ht@0,f2000000/pci@9/k2-sata-root@c/k2-sata@1/disk@0:
timeout=120
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
default=linux
defaultos=linux
fgcolor=white
bgcolor=blue
image=/boot/vmlinux
label=linux
root=/dev/sdb4
partition=4
read-only
macosx=/dev/sda3
enablecdboot
enableofboot |
The device= you find with ofpath /dev/sdxx
To install yaboot should be possible to use ybin from the cd, but you have to specify your yaboot.conf
It's a good idea always to use --verbose with ybin. |

I had dowloaded the latest ppc minimal install CD (2013-01-27) and Yes the base system with chroot-environnement is ready. Today I boot on the live-cd and enter these commands for entering in my environment :
| Code: |
mount -t proc none /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --rbind /dev /mnt/gentoo/dev
mount /dev/sda7 /mnt/gentoo/
chroot /mnt/gentoo /bin/bash
env-update
source /etc/profile
export PS1="(chroot) $PS1"

I got the 1.3.17-r1 installed now, i will try with the 1.3.16-r1
I will use your yaboot.conf adapted with my system and I'll destroy the last partition (/dev/sda9 boot). I gonna try to boot like that ....
I modify my yaboot.conf inside my chroot-environment with
