Installation Preparation…

Before we can install Mac OS X, we need something onto which we can install it. Normally, this is a Macintosh formatted hard drive. But PearPC does not use a physical hard drive. Just as it uses ISO disc images instead of real CDs, it uses hard disk images. A hard disk image is a file that contains what the emulated Macintosh thinks is a real, physical hard disk. PearPC also requires some other “tweaks” in order to create a working, bootable Mac OS X configuration. (Fortunately, I have done that work for you, which should save you a good 500mb in downloads).

Your download list for this portion of the tutorial looks like this:

PearPC
The hard disk image file prepared for a Mac OS X installation (about 6mb in size). This file is a self-extracting, compressed archive. Double-click it to extract it. Allow yourself some time and some hard disk space, as this image file decompresses from 6MB to 6GB.
The most recent version of PearPC (currently at version .31) for Windows, or Win32. I highly recommend the JIT version of the software

The Installation Process…

1. Create a folder on your C hard drive and name it PearPC. Unpack all the software that you downloaded above and place everything in this new directory.

2. Copy the OSX3.iso image that we created in the previous tutorial to the PearPC directory. This should leave you with three items in the PearPC directory: the main program directory (i.e., pearpc-0.3.1-win32-jitc) the hard disk image 6gb.img, and the OSX3.iso disc image. Copy the entire contents of the pearpc-0.3.1-win32.jitc to the PearPC directory that we created in step 1. Once you’ve verified that pearpc-0.3.1-win32.jitc is empty, delete it.

3. In the PearPC directory, locate the file named pearpc.example and open it with WordPad.

PearPC is driven by what it finds in this configuration file. Most of the items in this file are fine if left alone. However, we need to tell PearPC where to find both the OSX3.iso and 6gb.img disk images, and in what order to boot.

4. In WordPad, scroll through the text file until you come to the line labeled prom_bootmethod. The default value for this setting is auto. Change this value to select as is shown here:

prom_bootmethod = “select”

5. Continue scrolling through the textfile until you find the line labeled pci_ide0_master_image = “/test/imgs/linux.img”. This line tells PearPC where to find its hard disk image file. Edit this line to read like the following:

pci_ide0_master_image = “c:\pearpc\6gb.img”

6. Edit the line that reads pci_ide0_slave_image = “/dev/cdrom” to read like the following:

pci_ide0_slave_image = “c:\pearpc\osx3.iso”

7. Click File and Save As. Give this file a name of OSX.pearpc.

8. Open a command prompt by clicking Start->Run and entering the text cmd or command. Type CD c:\pearpc and hit enter. PearPC’s syntax is very simple: pearpc . For our example here, we type the following, and hit enter:

ppc osx.pearpc

9. PearPC launches (at last!). It presents you with a list of boot options. We wish to boot from the ISO disc image containing the Mac OS X installation material. In this case, we see that this is option 1. Press 1, and hit enter:

The Mac OS X installation boots (and boots very slowly; don’t get too impatient, as the install screen will eventually come up).

10. The Mac OS X 10.3 installation screen appears, asking for you to choose a language in which to install Mac OS X. Select your language of choice and click Continue. A welcome screen appears.Click Continue. Click Continue two more times, and Agree with the license agreement.

11. The installer asks for a location in which to install Mac OS X. Click the disk named PearPC and choose Continue:

12. Since we wish to perform a customized installation of Mac OS X, click the Customize button in the lower left of the installer window. Remove the checks from the items labeled Additional Applications, Printer Drivers, Additional Speech Voices, Fonts, and Language Translations. Click Install.

13. When the installation attempts to run a check on the installation disc, click Skip in the lower right corner of the screen.

You should now acquint yourself with a good book or a nice, long movie. Installation of Mac OS X can take hours. On a 2GHz Pentium 4 system, this basic installation tops out at about three hours.

15. Once the installation process completes, PearPC quits abruptly. This is normal. To finish things up, edit the macosx.pearpc once again, place a “0” after the line PearPC about the existance of a CD-ROM:

pci_ide0_slave_installed = 0

This tells PearPC that our CD-ROM is no longer installed. Now boot PearPC in the same way as in step 8 above, choosing 1 to boot PearPC into Mac OS X. Congratulations – you are now running Mac OS X on a Windows computer! (Note: when the Mac OS X Setup Assistant asks you for information on connecting to the internet, tell it that you are not ready to connect at this time).
