This wiki is based upon the Clover User Manual(Russian version) created by Slice.
What is Clover about? Obviously not about the grass growing on a meadow for the cows' pleasure. It is about a software, a boot loader of a new type, that allows Mac OS X to run on a common PC.
Apple restricts the usage of its operating system to its own devices, arguing that it can not provide functionality on devices it didn't produce in the first place. Well, users will take the risk. No commercial advantage is taken in order to avoid other legal complications. A non-Apple computer into which Mac OS X is installed is called Hackintosh; the label's origin is self-explanatory.
In order to start a hackintosh, a special boot loader is needed. There is a big variety of boot loaders, but they can be divided into two groups: FakeEFI and RealEFI.
FakeEFI was invented by David Ellion many years ago and operates on a simple principle: It assumes that EFI already did its work. It leaves activity traces (boot-args and tables tree) and EfiRuntime routines in a simple form in memory and starts the kernel mach_kernel. Chameleon works this way for instance and it has only a few downsides like a non-working Startup Disk preference panel. However it is possible for Apple to bring us with other difficulties because of missing Runtime Services. January 2013: This is now the case. iMessage stopped working because of the missing SetVariable() function.
RealEFI theoretically should be flashed instead of the BIOS but alternatively a loadable EFI can be used for those with a BIOS motherboard. This system was invented by Intel and is currently in active open source development at TianoCore.org. The boot loader is named DUET and here is the problem. It is capable of loading EFI but it is not designed to load Mac OS X. One more step is needed: adapting DUET to the requirements of Mac OS X. Newer motherboards already contain EFI but it is not suitable for running a hackintosh.
The name Clover was given to the boot loader by one of the creators of kabyl's project. He saw a similarity between the command key, which is only present on Mac keyboards, and the four-leaf clover.
Wikipedia: The four-leaf clover is an uncommon variation of the common, three-leaved clover. According to tradition, such leaves bring good luck to their finders, especially if found accidentally. In addition, each leaf is believed to represent something: the first is for faith, the second is for hope, the third is for love, and the fourth is for luck.
