THIS IS NOT WRITTEN BY ME!!!!! I am just conveying the message to those who might like this idea.

  * Download the source code for PearPC at
http://prdownloads.sourceforge.net/pearpc/pearpc-0.3.1.tar.gz. As of this writing, 0.3.1 is the most recent version.
  * Use tar to decompress the file with tar -xzvf pearpc-0.3.1.tar.gz. A directory called pearpc-0.3.1 will be created.
  * Go into this directory configure PearPC by running the configuration script as ./configure -enable-ui=x11 && --enable-cpu=generic. Even though the Xbox is an x86 processor, compiling with -enable-cpu=jitc_x86 will likely result in a failed compile. To explain, as of this writing, Xebian includes gcc 3.2 and gcc 2.95.4. PearPC will exhibit odd errors when compiled with any gcc between 2.95 and 3.3, so gcc 2.95.4 must be used. Unfortunately, gcc 2.95.4 does not work with the inline assembly used in PearPC when the jitx_x86 option is specified.
  * Type make && make install. If all goes well then /usr/local/bin on your computer should now contain a file called ppc. This file is the compiled binary.
If you are unable to get a successful compilation of PearPC or do not understand the above instructions, you may download a precompiled version for the Xboxhere.
Editing the PearPC configuration file and formatting the hard drive image
1. Download the following: a blank hard drive image filehere, a Darwin image file at
http://www.opensource.apple.com/darwinsource/images/darwin-701.iso.gz, a PearPC configuration filehere, and a PearPC video driverhere.
2. Decompress the image file using gunzip macosx_2gb.gz. Note that this file expands to approximately 2 gigabytes. Additionally, use gunzip to decompress the pearpc video driver and configuration file. Decompress the Darwin image with the command tar -xzvf darwin-701.tar.gz.
3. Make a directory called macosx. Move the decompressed hard drive image, Darwin image, video.x video driver and macosx.pearpc configuration file into it. Then, go into the macosx directory, run the command pwd and write down the full path to it.
4. Open the macosx.pearpc configuration file with the plain text editor of your choice. Xebian by default comes with both vi and nano. If you have never used vi before, you definitely want to use nano.
5. I will refer to the path that was written down in step 3 as PATH. Make the following changes to the macosx.pearpc configuration file:
  * a. Change ppc_start_resolution = "800x600x15" to "640x480x15".
  * b. Change redraw_interval_msec = 40 to 200.
  * c. Remove the # in front of #memory_size=0x8000000.
  * d. Change pci_ide0_master_image = "test/imgs/linux.img" to "PATH/macosx_2gb.img".
  * e. Change pci_ide0_slave_image = "/dev/cdrom" to "PATH/darwin-701.iso"
  * Save your changes and exit.
6. Start PearPC by typing ppc macosx.pearpc. You should see the following screen:
7. Soon after this screen disappears messages will begin appearing in the PearPC window and you should eventually see the following:
8. Mirror what is typed in this screenshot. Then, type: q, q, and finally reboot. PearPC should exit.
9. Start PearPC again. Eventually you should see the following screen:
As in step 7, mirror what is typed in this window. In addition, when you see "Uncompressing Apple16X50Serial," shut down PearPC.
Your hard drive image is now properly formatted, and you are ready to install Mac OS X.
Installing Mac OS X1. Once again, open the macosx.pearpc configuration file. Change pci_ide0_slave_image = "PATH/darwin-701.iso" to the location of your Mac OS X image. Save the changes and exit out of the text editor.
2. Start PearPC in the usual manner. After a while you should see the Apple Installer. Clicking continue, agree, etc. will eventually show the following screen:
Click on the hard drive labeled Darwin. A green arrow pointing to it will appear, as seen in the picture. Press continue.
3. After clicking continue you will get the following message:
Click OK, and deselect packages by clicking on the check boxes until your screen matches the picture below:
Click install.
4. After clicking install the following screen should present itself:
If it is late, go to sleep. If it is early, enjoy a day outside. This install varies on the time required to completion, but will generally take around 10 hours.
5. When you wake up/get back from the park, PearPC will have exited. Restart PearPC and go through Mac OS X User Setup and Registration.
6. Mac OS X is now installed:
