Known issues when using Qemu for OSX/Windows

Post by Cat_7 »

OSX/Windows

Restarting Mac OS 9.x doesn't work. Use Shut Down and restart Qemu.

Trying to run Classic (Mac OS 9.1/9.2) installed on the same disk as OSX requires changes to the system folder, which render the OSX hard disk unbootable. Use two partitions and install each OS on it's own partition.

After installing, you should reverse the order of cdrom image and hard disk image in the command/batch file (or remove the cd image entry completely), otherwise Mac OS might not start. It is not sufficient to only change -boot d to -boot c to boot from hard disk image.

Mac OS 9.0.4 can only be installed from certain CD(images) for Power Mac G4s, some iBooks and iMacs and the G4Cube.

Also, the mouse can be difficult to control when QEMU is windowed rather the fullscreen in Windows.

256 color mode is corrupted at the moment. It can also only boot in either 8-bit or 32-bit color mode, AFAIK.

Also, you can only use mac99 to boot Mac OS. g3beige doesn't work.

Using qemu-system-ppc28-vga.
Partitioned the empty_disk.raw to have OSX 10.3.9 and OS 9.2.1 (french) on different partions. Panther runs fine, and classic the same. But Can’t boot from the OS 9.2.1 partition even though selecting from the startup disk preferences pane.
Boots only on OSX.

Change the load order of your disk images from the command line :) Sorry; I forgot to mention that part.

Otherwise, it looks like the very latest OpenBIOS has been patched to allow dual boot on the same partition.

If you have two partitions, you'll need to set auto-boot to false and provide the partition number on which the other OS is installed. Something like this:

boot hd:3,\\:tbxi

Once you know the partition number and want to boot from it from the command line, you can set something like this in your command line :
-prom-env 'boot-device=hd:3,\\:tbxi

Best,
