With these patches and OpenBIOS r646, booting 'install64' on the following Debian CDs worked for me: debian-40r4a-powerpc-netinst.iso debian-503-powerpc-netinst.iso By default however you get the following error: invalid/unsupported opcode: 1e - 12 - 1b (782106e4) 00000000014080e4 1 invalid/unsupported opcode: 00 - 00 - 00 (00000000) 0000000000008734 0 which translates to: qemu-system-ppc64 is using a 32-bit CPU by default. '-cpu ppc64' (970FX according to OpenBIOS) worked, while '-cpu 970' was not recognized by OpenBIOS. If you change only the CPU to 'ppc64', it will be rejected: qemu: hardware error: Bus model not supported on OldWorld Mac machine That's why Alex mentioned '-M mac99' elsewhere, I guess. Can't we change the defaults? I believe the G5 was the first 64-bit Mac and is considered New World, so Old World shouldn't even be selectable IMO. `install64 console=ttyPZ0` only gets me to the penguin and appears to hang... `install64` gets me through to the installer screen on Linux/amd64 host. There are merely some FATALs visible while trying to load drivers for therm_* and windfarm_* devices ("No such device"). Andreas > Obviously, this change needs to be reflected in openbios.

Well, on older kernels this was console=ttyS0. > `install64` gets me through to the installer screen on Linux/amd64 > host.

When using the escc with Linux, we need interrupts. So instead of creating a dummy device, let's just map them to the openpic we have anyways. This makes Linux on PPC64 with console=ttyPZ0 work. Obviously, this change needs to be reflected in openbios. Patch for that follows this one. Please update the binary then.
