Adam Pash, over at Lifehacker. He says that it’s almost as easy as installing it on a Mac. To perform the installation, first you need to mess with the BIOS settings to match those found in the pictures he posted, then you torrent a file called “Kalyway Leopard 10.5.1 SSE2 SSE3″ off of BitTorrent and burn it onto a DVD. This is essentially an install disk for Leopard loaded with EFI files that Lets your hardware work with OS X.
Pop in the disc and boot with it, this could take a while. Once the disk boots, you must go to Utilities -> Disk Utility in the menu bar. Find the disk on which you want to install Leopard and format it to the Mac OS Extended (Journaled) format. Afterwards, click the Options button tot set the partition scheme (either Master Boot Record or GUID). Then hit apply and let it partition. Then quit Disk Utility and go back to the installer.
Click continue at the install screen, then agree to the terms but then you MUST hit Customize. Adjust the settings so they look like this. Then hit done and install Leopard. After you’re done, restart your computer and witness the Nirvana that is Mac OS X Leopard.
Note: My guide is just a crude summary of his, it is just to give you a run down of the process. Please do not install from my guide, it is imperative that you use his if you are actually going through with this. Also, read the comments for feedback on how the installation went for other people
