Trying to install Adélie Linux on iBook G4

Today I am trying to install Adélie Linux on my old iBook G4 that I have previously installed OpenBSD onto.

I used this iBook primarily with Octoprint, which I have ported as well. However, this turned out to not being upgradable, as many of the python packages are installed though ports and maintaining this is a nightmare. The only modern alternative to OpenBSD seems to be Adélie Linux for this iBook.

When I tried to boot using

boot usb0/disk:,\\:tbxi

I immediately got an error message.

GRUB!

Error: unrecognized number

invalid memory access

I suspect that GRUB does not understand the OpenBSD Disk. This is why I am now first trying to reinstall Mac OS X onto this machine - even though it would have been nice to make a backup using the live version of Adélie Linux.

I have downloaded a Mac OSX 10.5.6 ISO from archive.org and restored it using balena Etcher. At first I tried to boot it using the command above, but this failed. In the end I had to use the following commands:

dev / ls
devalias ud /pci@2000000/usb@1b,1/disk@1
boot ud:3,\System\Library\CoreServices\BootX

After this I was able to boot from a USB Stick and install Mac OSX. I had additionally have to repartition the drive and select the correct partition table.

However, after attempting to install Adélie now, the error persists. Not sure how to fix this, maybe I will just try to install another distro.
