Thank you everyone.

Well, that's the way I did it. I use a seperate HD for OSx86 so essentially it's a "single boot" install... And this is straight from the "readme" in the "pc_efi_v80.zip" file:

"- Easy installation --- For Single-Booting systems ---

Create directory iamefi in the root folder of your boot osx disk.

Copy all included files into it

Boot in Single User mode by mashing F8 key during boot (right after bios POST) type -s and press enter

Then enter the following commands

cd /iamefi

./startupfiletool /dev/rdiskXsX ./boot_v8

reboot

Whereas rdiskXsX is the partition where your OSX install is (you can check that out on Disk Utility in OSX)

And v* is the EFI version bootloader you wish to use.

Existing 10.4.10 and 10.5/10.5.1 kernels compiled from sources, made by Toh are already known to work with this package.

You can also use vanilla appleacpiplatform.kext for leopard, and vanilla applesmbios.kext, but you might experience some glitches in system profiler and incorrect processor recognition with the latter.

dsmos.kext is mandatorily needed for vanilla and binary hacked kernels.

All credits for this work goes to def, Turbo , netkas, Dmitrik. And all testers."

Straight from "netkas" himself (or maybe ToH)....

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

I just wanted to confirm if it was possible to do this on my only 320gb hard drive. Let me know, thanks.

well, i will try this with my internal osx installation (cloned from external usb install with efi), as there efi is not fully installed.
if it works, i will add the info to the wiki
