Zephyroth Leopard 10.5.1 AMD, does it already include EFI?

[WinLinMac01]

Hello everyone, I have Zephyroth's 10.5.1 on my system and was questioning whether or not it already has EFI installed when Zephyroth made the AMD image? I want to install 10.5.2 (from the AMD package Piratebay), and would like to know if it is safe to continue, because EFI is required. Thanks.

This is the prompt I receive before I proceed to the installation: This is the AMD 10.5.2 update. You use this at your own risk. I have included the updated kernel(9.2.0), System.kext and dsmos.kext for those with EFI already isntalled. If you don't have EFI installed be warned that you will sit at a black screen for about 2 minutes waiting for the desktop to load with the old kernel(9.1.0).
