Re: [OpenBIOS] [Qemu-devel] [PATCH, RFC] Mac99 (CHRP?) support

[Natalia Portillo]

Should't we stay emulating the machines as they were?

If we are emulating a Macintosh, it should have whatever controllers  
the Macintosh had.
If they does not work, specially for booting a third party system,  
they should be repared, and not be substitued for another one not used  
on that machine.

Tried to boot any Mac OS?
