Red Hat Bugzilla – Bug 998030
Switch from Yaboot to GRUB2 as the bootloader on the installation ISO for PPC
Last modified: 2013-11-24 02:27:20 EST
GRUB2 is already the default bootloader for Fedora PPC installed systems, but we still have Yaboot booting the installer. Switching to GRUB2 also on the installation ISO eliminates the burden of maintaining two different bootloaders on Fedora PPC.
Removing Yaboot and its 32 bits dependency packages from the installation ISO also helps us to keep the image size under a single-sided single-layer DVD capacity.
GRUB2 may also bring additional features for network boot, though this is not the focus of this change.
A patch for this change was sent to the anaconda-patches mailing list: https://lists.fedorahosted.org/pipermail/anaconda-patches/2013-August/005336.html
please note that lorax needs 2 additional requirements with this patch:
Other than that it worked for me with a virtual DVD drive on PPC.
As for the discussion on IRC, I filed bug #999069 so that we can track progress on the inclusion of a pre-built boot image on grub2 package for PPC.
Do you want me to update the patch to include a comment pointing to that bug? Is there anything else required to get this patch included in F20 and upstream?
Apple G5 does not recognize both images located on /stage/f19-20130813-grub2/ppc64/iso as valid boot disks even after pressing C during chime. Computer always boots from hard drive. Therefore not able to install Fedora 19 with GRUB2 bootloader.
Note this computer is currently running Fedora 19 with Yaboot successfully. Also this computer is able to boot from regular Fedora 19 PPC64 DVD.
Version-Release number of selected component (if applicable):
Fedora 19 PPC64 GRUB2 Stage DVD dated 13-Aug-2013
Steps to Reproduce:
1. Insert Fedora 17 beta DVD in
3. Press C after chime
Computer boots from hard drive
Menu option to start installation of Fedora 19 or initial Anaconda screen
Powermac G5 (late 2005)
Dual core 2 GHz
4.25 GB RAM
500 MB SATA
nVidia 7800 GT
Actions done to solve the issue:
- Tried both DVD and netinst CD
- checked SHA256 checksums for downloaded ISOs
- checked for burning errors
Steps to Reproduce:
1. Insert Fedora f19-20130813-grub2 DVD in drive
3. Press C after chime

There's a couple of things that were missed:
efika.forth is provided by yaboot. ppc64 does not need it to boot (tested by gustavold)
'yaboot' is still on the installpkg line in runtime-install.tmpl. The resulting error while running pungi is harmless, but why be sloppy?
lorax-20.1-1.fc20 has been submitted as an update for Fedora 20.
Can anyone with a Powermac G5 test the iso bellow please?
It's the same one from koji  with additional files for MacPPC. Maybe this fix the problem.
Adding to AlphaFreezeException - Power can't compose without the patch in Comment #5 as well as the earlier patches.
+1 FE from me - this is blocking PPC compose and there is almost no risk to PA
* should fix your issue,
* was pushed to the Fedora 20 testing repository,
* should be available at your local mirror within two days.
Update it with:
# su -c 'yum update --enablerepo=updates-testing lorax-20.1-1.fc20'
as soon as you are able to.
Please go to the following url:
then log in and leave karma (feedback).
As it blocks PPC from composing it should be FE.
+1 FE, blocks PPC compose, changes in PPC templates
Fedora-20-ppc64-netinst_pfsmorigo.iso is not recognized as a valid boot CD by Apple G5. Same result as original Fedora f19-20130813-grub2 DVD as described in comment #3
that makes +3 FreezeException, moving to accepted
This bug appears to have been reported against 'rawhide' during the Fedora 20 development cycle.
Changing version to '20'.

Please see the following bug for a solution to the boot issue on Apple G5:
If any maintainers read this, please integrate the fix into Fedora 20 ppc64 Final so that we G5 users can boot it.
