I did a little further digging for you, BFFF. This may sound a little daft, but got it right out of the Tiger's EULA. You can't legally , install any Mac OS on a non Mac platform. It violates the licence agreement. You CAN, however, install XP on a Mac box. Go figure. Here's where you can get sneaky and get around the EULA. Install Tiger to a removable drive. It's not technically an Intel rig as it can be anything and it's not located INSIDE the box. Here's a link to do it using windows, to do the actual install. http://www.tech-recipes.com/apple_mac_tips964.html The Tiger EULA just mentioned "installing", not running. I can't vouch for how it would stand up in a court of law, but the way it's worded certainly supports it. Edit: Bingo...here you go http://macdailynews.com/index.php/weblog/comments/7523/

In order to run Mac OS X 10.4.x (Tiger) and Windows XP on the same computer, you need any one of Apple's Intel based Macintosh computer (http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore/). You then need one of two enhancements. You need either Apple's Boot Camp (http://www.versiontracker.com/dyn/moreinfo/macosx/29549) or you need Parallels (http://www.versiontracker.com/dyn/moreinfo/macosx/29555; note Parallels does not work with the Mac Pros (the high-end mini-tower computers) as of this time). Finally you need a copy of Windows XP. Boot Camp and Parallels handle things very differently. Boot Camp sets up the computer so that it can boot into either Mac OS X or Windows XP. You can't have them both up at the same time. On the other hand, Parallels sets things up so that you can run both OS's side by side. Thus you have both OS running at the same time. Parallels is also not limited to just Windows XP. It can run just about any other Intel compatible OS along with Mac OS X. Finally, there is one other way to run windows on a Mac. This is to use VirtualPC (http://www.microsoft.com/mac/products/virtualpc/virtualpc.aspx?pid=virtualpc) with one of PowerPC based Macs. This, however, is not as good as the above options. With the above options, you are running the Windows OS natively on the Intel processor in the computer. With Virtual PC, you have to created a simulation of a PC that then runs on the PowerPC processor. Since Windows is running within the simulation which is then running on the CPU, VirtualPC runs much much more slowly. It is my understanding that Windows XP is very slow in this environment. Most reviews suggest using Windows 2000 instead if you want something that runs at a reasonable speed. So, these then are your options to run Windows XP and Mac OS X on the same computer, get an Intel based Mac and Boot Camp or Parallels or get a PowerPC based Mac and use VirtualPC. You won't be able to run both OS's on any computer that is not made by Apple. Apple makes its money on the hardware. So, they make sure that the Mac OS will only run on their computers. **************** Addendum" After completing this entry, I noticed that scubabob had posted an answer telling how to install OS X on a non-Apple PC. I also noticed that he says that this method is of questionable legality. Furthermore, I noticed that the actual instructions on the site he referenced ends with, "If your hardware is compatable, you should boot to OSX." If your hardware is compatible... In other words, there is no guaranty that this will work. On the other hand, the methods I describe are definitely legal and have been shown to work reliably.
