Build Directions

Guest Installations

Mac OS/Mac OSX

Mac OS 9.x

Command-line options to install Mac OS 9:

 ./qemu-system-ppc -M mac99,via=pmu -m 512 -hda <hd image file> -cdrom <iso file of installation media> -boot d -netdev user,id=mynet0 -device sungem,netdev=mynet0

Mac OS 10.X

Command-line options to install Mac OS 10.X:

 ./qemu-system-ppc -M mac99,via=pmu -m 512 -hda <hd image file> -cdrom <iso file of installation media> -boot d -netdev user,id=mynet0 -device sungem,netdev=mynet0

Mac OS X Server 1.2v3

Installation requires several steps:
Step 1: boot from installation CD, use disk utility to partition disk as Apple Server, quit Qemu and reboot with command line in step 2.

 ./qemu-system-ppc -L pc-bios -boot d -M mac99,via=pmu-adb -m 256 -net none -prom-env "auto-boot?=true" -prom-env "vga-ndrv?=true" -prom-env "boot-args=-v" -sdl -cdrom OSXServer1.2v3.iso -hda OSXServer1.2v3.qcow2

Step 2: initial installation (note machine and CPU, otherwise no desktop is shown).

 ./qemu-system-ppc -L pc-bios -boot d -M g3beige -cpu G3 -m 256 -prom-env "boot-args=-v" -prom-env "auto-boot?=false" -net none -sdl -hda OSXServer1.2v3.qcow2 -cdrom OSXServer1.2v3.iso

At the boot prompt enter "boot cd:9,\\:tbxi" Initial installation starts. Quit Qemu after completion.

Step 3: Installation continued. Boot with the following command line to complete the installation.

 ./qemu-system-ppc -L pc-bios -boot c -M g3beige -cpu G3 -m 256 -prom-env "boot-args=-v" -prom-env "auto-boot?=true" -net none -sdl -hda OSXServer1.2v3.qcow2 -cdrom OSXServer1.2v3.iso

Step 4: Boot the installed system:

 ./qemu-system-ppc -L pc-bios -boot c -M mac99,via=pmu-adb -m 256 -prom-env "boot-args=-v" -prom-env "auto-boot?=true" -net none -sdl -hda OSXServer1.2v3.qcow2 -cdrom OSXServer1.2v3.iso

Linux

Mac OS 9 Debugging tips

Macsbug can be used to tell you what exactly stopped booting. The link for it is below.
Mac OS 9.2 comes with a built-in debugger. To use it, set the OpenBIOS variable &#147;APPL,debug&#148;:

Via QEMU's command-line options:

 -prom-env aapl,debug=2000000

In OpenBIOS type:
dev /
2000000 encode-int *Note: the number can be replaced with the many options available
&#147; AAPL,debug&#148; property
then to boot from a cd type:
boot cd:,\\:tbxi

To boot from a hard drive image:
boot hd:,\\:tbxi

Emulated hardware issues

Linux is able to use a wide variety of emulated hardware available to QEMU. Sound and networking devices work well with it.

Mac OS 9 and Mac OS X currently only support sound in experimental builds.

How do I help

QEMU has many systems that can always be improved. Here is a brief list of possible areas you may want to work on:

  • Documentation
  • Testing
  • Fixing operating system compatibility issues
  • PowerPC emulation
  • User interface
  • OpenBIOS (firmware)
  • Implement a sound card that is compatible with Mac OS 9 and Mac OS X. The usb-audio device is the closest to working on the Mac OS.
  • Implement a 3D video card
  • Improve various hardware (via-cuda, ata controller, etc..)


Knowledge in these areas could help:

  • PowerPC Assembly
  • 68K Assembly
  • Embedded Programming
