OpenBIOS is not able to boot MacOS X.
Well, that's a silly limitation. Is there a reason this isn't implemented? I see that the Mac-on-Linux OpenBIOS version has such support, so it seems strange that the QEMU version does not.
I don't know if anyone here is actually interested (this list seems -very- quiet), but...
I've been hacking at OpenBIOS for a bit, and I got it to properly read Mac OS X discs (it kept failing because it would hit an Apple Partition Map header instead of an HFS+ filesystem header). I'm working on adding an XCOFF loader, too, so it should be able to boot Mac OS X soon.
Any chances I could get these changes merged to the main OpenBIOS tree once they're done?
My current working repository is at http://github.com/tycho/openbios. I'm working on the macosx-boot branch. The relevant commit is here (patch also attached): http://github.com/tycho/openbios/commit/4722c8a01d186a08183de49759dc8b7b74cf...
Thoughts?
Your work surely sounds interesting. However, making OpenBIOS boot from the disks is not everything there is to it. Alexander Graf had once posted a series of patches for making Mac OS X boot in QEMU, including changes/additions to device emulation. They were not merged, not sure about the status today.
One issue iirc was that you need to obtain some Apple ID from a real Mac of yours and pass that to QEMU for it to work.
