[opensuse-ppc] Booting into Tumbleweed on a G5
Hello everyone, I'm trying to install tumbleweed ppc64 onto an old Mac G5 for a friend (completely replacing the old OS X on the machine). The install (from a DVD-RW) actually went fine... but I can't boot into it. All I see on boot is the finder icon alternating with a "?", like it can't find any boot partition or boot code. The installer did create a "PowerPC PreP boot" partition on /dev/sda1, but somehow the ?BIOS? doesn't find it? Do you have any hints as to what might be wrong, and/or how to debug this?

Please find a guide on installing bootloader on an Apple based ppc machine. The way firmware locates the binary to load is implementation-defined. The installer has been rewritten recently and does not support Apple hardware. The hardware is not exactly common so it is not easy to develop and test support for the platform.

Heh, so both "RTFM" and "implement it yourself"? I was hoping for a slightly smaller time investment :-)

And yet it created an Apple-specific boot partition? I guess you mean that about the part about the firmware locating the binary to load though. I'm just curious about what you mean by that sentence exactly.

No doubt about that. I can offer some testing, but not really development, I have plenty of that to do on other topics already ;) Thanks, -- David Faure, faure@kde.org, http://www.davidfaure.fr Working on KDE Frameworks 5 -- To unsubscribe, e-mail: opensuse-ppc+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ppc+owner@opensuse.org

That's probably *NOT* the partition the Apple firmware expects which is the cause of your problem. Thanks Michal -- To unsubscribe, e-mail: opensuse-ppc+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ppc+owner@opensuse.org

FTR the issue is reported here http://bugzilla.suse.com/show_bug.cgi?id=1079435 and you might even get some information on how to install in the bug report. HTH Michal -- To unsubscribe, e-mail: opensuse-ppc+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ppc+owner@opensuse.org

Do you have any hints as to what might be wrong, and/or how to debug this?
My PowerBook G5 is a 32-bit processor. Is the desktop version 64-bit? Selecting a distro for the 32-bit units is not easy. Given my natural inclinations and prejudices, I tried everything I could to get anything but Ubuntu to work. Initially, Mint worked, but its PPC version was dropped. I thus ended up running Ubuntu 12.04 LTS. It works fine for what I do, which is generate modern kernels to test for bugs. Most PPC development is done for 64-bit systems, and it is not always correct for PPC32. Over the last 3 years, I have detected about 1 bug per year that causes a boot failure. I seldom can determine the fix, but at least I am able to bisect to the bad commit. If you decide to go the Ubuntu route, write me privately, and I will give you some additional pointers.

Yes, this is a 64 bit machine (I mentioned "ppc64"). I might try Ubuntu indeed, if OpenSuSE can't boot, but I wanted to try just a little bit longer first, I like OpenSuSE ;) Thanks. -- David Faure, faure@kde.org, http://www.davidfaure.fr Working on KDE Frameworks 5 -- To unsubscribe, e-mail: opensuse-ppc+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ppc+owner@opensuse.org

Apple PowerPC-based laptops (Powerbooks and iBooks) started out with G3 processors, and ended with G4 processors. All were 32-bit and none shipped with G5 processors. http://everymac.com is a good resource to identify the exact model and specifications, given the machine serial number. https://forums.macrumors.com/forums/powerpc-macs.145/ is a reasonably active discussion forum for all PowerPC based Macs. Debian (PPC ports), Adélie and Void have ppc32 distributions. Al -- To unsubscribe, e-mail: opensuse-ppc+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ppc+owner@opensuse.org

PReP is for IBM POWER systems, useless for Mac. You need a mac disk label, with a Apple_Bootstrap partition formatted as hfs with a special layout. The ppc version of lilo can format such a boot partition. I don't know if grub has support for booting a Mac.

Hi, Thanks for the information. My setup is all working now. It turns out that the easiest way to create a mac partition table, the necessary partitions, and have yaboot installed is... the Ubuntu 16.04 installer. At that point I can probably install OpenSuSE again, which yaboot will be able to boot into :-) Cheers, -- David Faure, faure@kde.org, http://www.davidfaure.fr Working on KDE Frameworks 5 -- To unsubscribe, e-mail: opensuse-ppc+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ppc+owner@opensuse.org
