qemu commands are very simple and basic:

qemu-system-ppc -k it -m 1024 -boot d -hda disk.qcow2 -cdrom cdrom.iso

or

qemu-system-ppc64 -k it -m 1024 -boot d -hda disk.qcow2 -cdrom cdrom.iso


This evening I will post the test for OSs with old (r828) revision of openbios inside qemu.

Great - thanks for helping with this!


ATB,
