By default, qemu-system-ppc emulates a CHRP.

To run AIX 4.3 and 5.1 you can use a 32bit machine (qemu-system-ppc), to run AIX 6.1 you need a 64bit machine (qemu-system-ppc64).

But to be able to run AIX, there are some improvements to add:
- to OpenBIOS: at least RTAS is missing.
- to qemu: emulate hardware supported by AIX (disk controller, network interface, graphic card, ...)

As said before: patches are welcome...

Regards,
Laurent
