Use this sources.list [1] and then install "firmware-amd-graphics".

For the iSight camera, you can just download this file [2] and place
it below /lib/firmware.

For the b43 firmware, you need to install the b43-installer along
with the b43-fwcutter. The latter is currently not built for ppc64,
but I can do that manually later this week.

Hi all,

in the meantime I succeeded in installing Debian 12.0.0 on iMac G5 with radeon

card.

I used ISO-Image 2023-06-18, installed default with tasksel KDE plasma, LXDE 
and LXQT.

I had to insert "radeon.agpmode=1 radeon.modeset=1 video=offb.off nomodeset" in 
grub
to get graphic mode.


Just for future references. On my iMac G5 I've the Nvidia GeForce and the
nouveau driver. I had to set "video=TV-1:d" to avoid continous error ("DDC
responded, but no EDID")


Now firmware R300_cp.bin, b43 and isight.fw is missing. I can not install this 
firmware
from the indicated sources.

/etc/debian_version is telling me, it is trixie/sid, but 12.0.0 should be 
bookworm stable.

Can I change /etc/debian_version to bookworm and change the 
/etc/apt/sources.list to
bookworm? Should I download the missing firmware by hand and install it?

With LXDE I can work although it is rather slow.


I'm using i3 and the performance is fine. It might take a while to get used to 
i3.


Firefox hangs, konqueror will not show
google. Are there any tricks to make that better?


I'm struggling as well in finding a decent browser for such an old hardware.
I've in the pipeline to try ArticFox (https://github.com/rmottola/Arctic-Fox)

A bit extreame perhaps. You could try `lynx` and friends.


Otherwise the iMac G5 is not usable.

I don't think you can boot from USB on G5's. Or I was not able to boot
from a USB thumb drive when I installed Debian on my PowerMac G5. The
Open Firmware would not allow it. I had to burn the CD or DVD.


Actually yes, you can boot from USB on the iMac G5. Here it is the procedure:

0. prepare a USB key with the netinstall image using ``dd``

1. hold ``Command + Option + O + F`` while booting until you get the
OpenFirmware command line

2. type the following command ``boot usb/disk@:,\``

Replace  with the USB port number you are using. On the iMac G5 they go from
0 (top) to 2 (bottom).

Replace  with the disk number assigned. This is usually 0 or 1.

Replace  with the full path to the grub bootloader.

In practice, assuming that you have the USB key in the top USB port.

```
boot usb0/disk@1:,\boot\grub\powerpc.elf
```

How do you find this yourself? Using ``dev / ls`` you get the hardware layout
(device tree). In there you will see a node under a PCI endpoint named
``disk@``. Remember type ``devalias``, and you will see that a ``usb``
name is mapped to the PCI endpoint you found before.

Hi all,

now I could install
debian-12.0.0-ppc64-NETINST-1.iso
from 2023-05-28.

But grub would not install.

I can boot into grub.
The partition is (ieee1275/hd,apple3) and I can find the kernel in /boot:
config-6.2.0-9-powerpc64 vmlinux-6.1.0-9-powerpc64 initrd.img.old vmlinux.old 
vmlinux
System.map-6.1.0-9-powerpc64 initrd.img initrd.img-6.1.0-9-powerpc64

now I am somehow lost.
What should I set for root?
set root=(ieee1275/hd.apple3)
gives no error, but
linux /boot/vmlinux-6.1.0-9-powerpc64 root=/dev/sda3
-> error: no server is specified

Any hints?

Hi John, hi Frederico,

I tried debian-12.0.0-ppc64-NETINST-1.iso from 31.1.2024.

The Mac G5 stops with
smp_core99_probe
smp_core99_bringup_done

I tried with
radeon.modeset=1 video=offb:off nomodeset
radeon.agpmode=-1 radeon.modeset=1 video=offb:off nomodeset
in grub. No better.

Now I have the problem, that I don't get the DVD out of the drive. With my try 
of
debian-11.0.0-ppc64-NETINST-1.iso from 14.5.2023 I partitioned the hard drive. 
So there is
no bootable kernel on the hard drive.

Can I boot from USB?

Any hints?

Re: Debian 12 on iMac G5

2024-01-23 Thread Federico Vaga

Hi Claudia,

perhaps there is a misunderstanding. I'm trying Debian 12 ppc64 
Big-Endian.

My suggestion to you is to try the proposed fix from the fienixppc team.
I report here what is mentioned in their article (I copy only what is of
interest to you).

```
[...]

 the system shows only a black screen, a black screen with a cursor, or 
a garbled image:
These issues are caused by driver configuration issues. Try entering the 
below boot parameters when you see the yaboot prompt (when booting up 
your system).

Radeon GPU

[...]

If you have a Radeon GPU, try entering the following boot parameters 
(one at a time, must be entered EXACTLY as listed):


"Linux radeon.modeset=1 video=offb:off nomodeset"
"Linux radeon.agpmode=-1 radeon.modeset=1 video=offb:off nomodeset"
```

In other words, using grub, try to add to the command line paramenters
"radeon.modeset=1 video=offb:off nomodeset" or
"radeon.agpmode=-1 radeon.modeset=1 video=offb:off nomodeset"

In my particular case, my iMac has an Nvidia card, therefore I tried
another set of parameters. For me, it did not help. But you are using
a different card with a different driver. It might be of help.
