[Qemu-discuss] PPC 7455 doesn't start

[Jörg Sommer]

Hi,

I've an iBook G4 which is a PowerPC 7455. Hence, I've thought it would
get the best performance it qemu uses this CPU for the guest system. But
the guest system doesn't start. The windows stays black. I can switch to
the managment console and quit qemu.

% qemu-system-ppc -M mac99 -cpu 7455 -prom-env 'auto-boot?=false' -k de

Don't setting the CPU type gives me an OpenFirmware prompt, but then it's
not a 7455 CPU.

This is my host CPU:
