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).

Nope, no EFI. It's easy to install efi though. Look in the miscelaneous section of the wiki for instructions. Just follow those simple instructions and you'll be on your way with EFI.

What is the link again?

never mind found the link, /osx86.wikidot.com

Will this affect my existing installation, like overwriting the files? http://osx86.wikidot.com/misc-information What would happen if I was to install that file that I was referring about that's on pirate bay?

What do you mean, exactly?
Installing EFI just "adds" the EFI bootloader.
replacing AppleSMBIOS.kext is not mandatory.
As for installing the AMD package, it looks like it needs EFI installed for fully working.
Of course will the update replace many files and could wreck your 10.5.1

is there any way I can get the EFI to install in my operating system without using a jump drive?

You can use an external harddrive or another internal drive.

Ya, after you have the "iamefi" folder on your root drive:

Boot in "single user mode" ( press a key (or F8) at the "countdown" and type -s at the prompt - hit Enter )
At the prompt:
cd /iamefi
( the prompt will change and say "iamefi" in there somewhere - sorry, at work and don't remember the actual verbage )
./startupfiletool /dev/rdisk0s1 ./boot_v8 ( here you need your ACTUAL drive and partition numbers in the "rdiskXsX" !!! )
( it'll say some stuff here - 4 or 5 lines before it's complete. doesn't take long. )
reboot

Once it boots the "EFI enhanced...." goes by so quickly you don't really see it - it mostly looks like a normal boot. There's a tool refered to in one of these threads that's lets you see the EFI parameters once you're in the OS X Desktop... Look around, you'll find it.

Running both 10.5.8 and 10.6.4 on my stinking AMD/ATi machine...

the tool is called IORegistryExplorer, you can get it at the wiki.
