After downloading Rebel EFI,
[..] users simply insert a retail copy of the Snow Leopard DVD, follow the installation procedures and then install the application. The application automatically detects connected devices and downloads the appropriate drivers.
Rebel EFI features Psystar’s DUBL (Darwin Universal Boot Loader) and a Safe Update mode, that prevents users from installing updates that could break their systems. The Safe Update mode only installs Psystar approved updates.
In contrast to the EFI-X manufacturers, Psystar in the past has released several drivers for free to the OSX86 scene. The advantage of Rebel EFI in contrast to solutions like the Chameleon boot is that is already comes with an automized hardware detection and a bunch of downloadable hardware drivers. Chameleon on the other hand is available free of charge and a lot more powerful for users in the know. So decide for yourself which product fits your needs the best.
A single license for Rebel EFI costs about 50US$ and can be ordered here.
