This guide wouldn't be here without the help two big osx86 communities: osx86scene.com and insanelymac.com. I only gathered all information and put it together in one easy to read guide.
インストール前に必ず読むこと Don't forget to read this before installing
I forgot the 'requirements' section on purpose. Please read through the whole guide and write down the things you need. This sounds stupid, but I want to force you to read through the whole guide prior to trying things out.
実行手順（The actual guide）
1. もしWindows XPを使用してるならstep 2へ。もしVistaならstep 3へ。
1. If you are using Windows XP go to step 2. If you are using Windows Vista, skip to step 3.
2. You need to create at least 6GB unallocated space on your hard disk. If you know how to do this, don't hesitate to use your preferred method. If you don't know how to do this, download Partiton Magic 8 and shrink one of the partitions on your hard drive. After you've done that, skip to step 4.
>> Click on ‘Resize/Move Partition >> Move the slider to make the partition smaller and hit OK >> Click on ‘Apply’ >> Close Partition Magic
3. You need to create at least 6GB unallocated space on your hard drive. To do this, follow the steps below.
>> Press the windows logo in the bottom left corner of you screen >> Right click ‘computer’ and select ‘manage’ >> Select ‘Disk Management’ in the ‘Computer Management’ screen. >> Select a partition with at least 6GB of free space >> Right click it and hit ’shrink volume” >> Type in the amount of space to shrink (at least 6GB) and hit ‘Shrink’. >> Close all open windows.
6. Insert the Leopard install disk (if you don't have it, search for a ToH RC2 disk on the usual places...) and reboot your computer.If it doesn't boot up your Leopard disk you may have to change your BIOS settings to alow booting from a DVD.
7. Wait for the DVD to boot up and select a language. Somewhere in the toolbar at the top of your screen (after you selected a language!) you'll see 'Disk Utility'. Open it and select the partition you created in step 5. Format it to HFS+ (journaled) and call it Leopard.
8. Follow all installation steps on your screen. Choose the HFS+ (journaled) partition you created in step 7 and don't forget to hit customize. Depending on the install disk you use you need to select or deselect packages.
9. インストールはPCによりますが、1時間ほど掛かります。コーヒーでも飲んで祈りましょう。
9. The install will take about an hour, depending on your computer configuration. Take a cup of coffee and start praying.
14. Restart the computer and hit F8 when you see the bootloader. Type in "cpus=1" and hit enter. If you still get a kernel panic, read on, otherwise skip to step 16.
15. BIOSでSpeedStepを無効にしてください。Leopardを立ち上げてください、まだ動きませんか？ セーフモードで起動してください（type -x in the command line）もし起動しないなら、step 17（＊原文step16は間違い？）へ。 （＊2008/2/4 訂正）
15. Boot into your BIOS and disable SpeedStep. Try to boot Leopard now, still not working? Try to boot it in safe mode (type -x in the command line). if it's still not working, go to step 16.
18. You should now have a working dual boot configuration! Maybe there are still a few things not working like you hoped, search the forums at forums.osx86scene.org and forum.insanelymac.com for help. If you search the board before posting and use common sense, I'm sure that the community will help you.
Spacesでのドラッグしてのスペース移動遅延を短くできたり、Time Machine保存時間を1時間以外にしたり。それ以外でもメニューバーを非透過、常に印刷時は拡張印刷設定などは特に使えます。元ネタは英国サイトのMac OS X Tipsより。
＊ Terminalへのコマンドはコピペ推奨。自己責任でお試し下さい。 ＊ 設定更新にはアプリの再起動が必要。ただしDockとFinderの再起動は次のコマンドを使う。Spaces、Stacks、Dockに関しては" Killall Dock "を、Finder関連は" Killall Finder "。
Allows you to increase the size of the Dock past the maximum allowed by the slider in System Preferences. Don't go larger than 256. Use the slider in System Preferences to shrink the Dock down again.
Allows you to increase the Dock magnification past the maximum allowed by the slider in System Preferences. Don't go larger than 512. Use the slider in System Preferences to shrink the Dock down again.
Makes all items in the Dock spring loaded. For example, hold a file over an application and it will open or come to the front so you can drop the file onto a specific window. Repeat with NO to reverse.
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user "このアプリケーションで開く"をリセット。Tigerのときのコマンドと違っている。
Resets the "Open With" menu, clearing duplicates. The command is different from the one in Tiger.
Enables the Debug menu in iCal, just like the Safari one. Repeat with NO at the end to disable.
Safari

Disables the warning given when closing a window with text entered into a form that you haven't submitted. To bring back the warning, repeat the command with YES.
Mac Fan12月号P55にあるように、毎日TV番組の録画およびiPodへの転送をする場合、1時間500MBの元データにさらにiTunesで変換で500MB（これは本来小さくなるでしょうが）、それを10日で10GB。とかも運用を考えずにTime Machineを使えば十分にあり得る話です。 また家族旅行のハイビジョン動画を毎日少しずつ編集していったらどうなるでしょう。
