Recently there has been a lot of progress on the OpenBIOS side to get Mac OS X to boot.
For a while now it seemed there was only very little to make it a fully working guest os in QEMU. This patch set is the result of this. With this I can successfully boot Mac OS X 10.2 to 10.4 with the g3beige machine all the way to the GUI. I was not able to boot 10.0 or 10.1, both of which crashed in interrupt controller registration. 10.5 does not include drivers for g3beige anymore. Everything as of 10.6 is x86 only. The mac99 target doesn't look quite as good, but also very close. FWIW only minor issues in our NVRAM layout and via-cuda emulation keep us from using that one. Please don't try to run this with KVM yet. Mac OS X uses mixed mode (half real, half paged) extensively, which happens to break badly in KVM.
