Hello everyone,

Did anyone have any success installing T2SDE Linux on PowerPC? The installation goes buttersmooth, but I always get stuck at the grub shell, no matter how I get around partitioning (tried /boot in separate ext2 partitition, tried GPT and APM). I don't even get the menu with the menu option defined in grub.cfg during installation.

I am on a late 2005 G5.

i had the same problems. I tried it many times to install T2 SDE 24.5 only to recognize that you

1. cannot make a hfs filesystem (must do it before installation with OSX install media for instance), make.hfs is missing.
2. T2 SDE cannot mount a hfs filesystem read/write, only ro.
3. T2 SDE cannot write anything to the boot partition (normally /dev/sda2)

Maybe some linux wizard can enlighten us with some help.

it's a pity that in June 2024 almost all ppc linux derives would not install on our beloved ppc machines.

1. debian 12: broken dependencies and broken grub
2. T2 SDE: unable to boot after installation
3. debian 11: cannot finish install
4. debian 10: no mirror anymore, cannot install anything
5. Adelie works on my iBook after endless tries. don't DL the usual PPC iso, just DL the adelie-inst-ppc-1.0-beta5-20240426 with size 488,3MB. but Adelie has a small repository. package manager is fast.
6. void linux: i had it once installed, years ago, it was fast, easy and reliable, but support ended AFAIK in 2023.

last warning. DON'T try to install t2-23.12-ppc-minimal-firefox-gcc-glibc-603 !!!! it bricked one iboob and one powerbook, I suspect the installer to inject some code into OpenFirmware. both devices were unbootable! after hours of research I found the following hint:


and rescued both ppc machines!

I would love to continue some kind of exchange about the possibilities of linux in June 2024 for us!
 
I spent some time on this yesterday and today, failing miserably.

Even the known media I have for void ppc and adelie I failed to install - perhaps my memory is failing. It was easier to get my C8000 up and running!

I am trying to get Debian 10 up with functional grub, then will try to get t2sde on top of it, by mounting /boot/grub and /boot separately. Let's see.

Try my recommended Adelie image, the you‘ll succeed!
 
Did you try loading t2sde on top of a working bootable environment created by the adelie installer?
 
No, I tried to install from scratch but did the partitioning and formatting from OSX 10.5 installer disk or diff. Linux install disk cause T2 SDE does not support hfs.
 
I guess this is the T2 linux thread, so I thought I'd put some notes here from my experience installing it on a Mini.

T2 linux may be one of the most up to date versions that still installs/runs on our hardware. It may be one of the most linuxy versions too, as everything builds from source that is downloaded from the internet and you need to be somewhat knowledgeable to get anything done. This is good in most ways, but if you're in a hurry, cross compiling from some other machine may be faster. Any package not included in the installer will need to be compiled. In my case, it's still cold out and I have excess solar electricity to burn (and heat the house), so having one or more computers in the corner compiling stuff continuously is a benefit.

To get started with installation on the Mini, download
dl.t2sde.org/binary/2024/t2-24.12-ppc-base-wayland-glibc-gcc-603.iso

from dl.t2sde.org/binary/2024/

I think the version is simply the year.month that it was compiled and there may be newer ones as you read this. Then put it on a USB stick. From a command line (Terminal) confirm the USB location with: diskutil list then put the image onto the USB stick, from the download location e.g.:

dd if =./t2-24.12-ppc-base-wayland-glibc-gcc-603.iso of=/dev/rdisk2 bs=1m

There will not be any indication of progress from the command line, but you can open Activity Monitor and watch the Disk Activity if you want. For me it only took a few minutes on the Mini with ~10MB/s transfer rate. When it finishes it should mount in Finder and show the contents of the installer.

Then boot the Mini from the USB stick. From Open Firmware, confirm the USB stick is recognized:
dir ud:,\\ then boot with boot ud:,\\:tbxi

I followed most of the default options for installation, except I used ext3 filesystem so the files should be accessible from other (older) versions of linux if needed. Most of the documentation www.t2sde.org/documentation/ refers to running the "./t2" script, which doesn't exist in the installation until you connect to the internet and do:

cd /usr/src/t2-src svn up

I finally figured that out when I found this page (has a bunch of other useful info): www.t2sde.org/kb/8/

You will want to add users besides root with commands like:
groupadd someone useradd -m -g someone someone passwd someone

As with most other linux versions you can have multiple logins/screens to see what's going on with Option-F1/F2/F3 etc.

I wanted to see if gcc14 is any better than gcc4, or if it just has 10 more layers of bloat. I'm now compiling different things to compare against the same code compiled with gcc under Mac OS X 10.4...
