#234708 — Installing Debian 10.9 Buster on iMac G5 (powerpc)

[Multipart message — attachments visible in raw view] — view raw

I am trying to install Debian 10.9 on the old iMac G5. I burned the
'debian-10.9.0-ppc64el-netinst.iso’ image to CD on a newer iMac (2017).
When I boot the iMac G5 holding the ‘Option’ key down with the CD inserted,
the G5 doesn’t recognise the CD as a bootable CD. I then did the same with
the 'debian-bullseye-DI-rc1-ppc64el-DVD-1.iso’. Till the same problem. I
was able to install Ubuntu Mate 16.04 for powerpc without any problem.

Can you please help me to solve this problem?

Kind regards

Pat

Hi Pat,

Debian has 3 architecture for powerpc :
 - ppc64el (official)
 - powerpc (unofficial)
 - ppc64 (unofficial)

Only official architectures have testing and stable branches. Unofficial
architectures have unstable/sid branch only.

I'm not sure what computer architecture your old mac belongs to so try
to use the same architecture you have used with Ubuntu.

Kind regards
Georgi

Hello,

 From what I understand (If I understand correctly), your processor is a 
powerpc64 Big Indian, not a powerpc64 Little Indian and nowadays the 
rare Linux ditros that still propose a powerpc64 portage do it for Litte 
Indian (ppc64el) as Debian do. So Debian is not compatible with your 
hardware.

The only distros I have found that seem to support your hardware are Gentoo
https://www.gentoo.org/downloads/ (download the PPC64 stage3 image, not 
the ppc or ppc64le ones)
and Adelie (the distro is in RC (release candidate) stage but ther are 
even live images)
https://www.adelielinux.org/download/

Even the *BSD seem to lack support for the Imac G5

That's "Endian", not "Indian".

Thank you Greg, but I promise you, Your Honor, I'm not guilty, for the 
life of me ;-)

In this case, I did know the concept and its correct spelling but:
- being absent-minded by nature
- thinking in english (I have  almost wrote "inglish")
- but unconsciously verifying spelling in french (my native language) 
while writing
- and being guilty of not re-reading myself before posting

You have there a perfect recipe for a disaster ;-)

That is cute and it reminds me of Peter Sellers in "The Party"
... talking of little Indians and disasters ...

Possibly you want Debian for "ppc64" or "powerpc".
At least the boot equipment of debian-10.0-ppc64-NETINST-1.iso and
debian-10.0-powerpc-NETINST-1.iso looks like the one of
ubuntu-mate-16.04-desktop-powerpc.iso.
(I.e. CHRP MBR partition and Apple Partition Map announcing a HFS
filesystem. Made by genisoimage. The Debian ppc64el ISO has only CHRP
and was made by xorriso.)

See
  https://wiki.debian.org/PPC64
  https://wiki.debian.org/PowerPC

The latter mentions "G5 Power Macs".

There is a mailing list
  https://lists.debian.org/debian-powerpc/
where searching for "G5" yields lots of hits
  https://lists.debian.org/cgi-bin/search?P=G5&DEFAULTOP=or&B=Gdebian-powerpc&SORT=&HITSPERPAGE=10

So i guess your goal is on topic there.


Have a nice day :)

Thomas
