Problem installing EFI on AMD SSE3 (nForce4 Ultra mb)

[wsalex]

Hello,

 

I have installed the Leo on the second hard drive (partition 2, active, mbr partitioning scheme) using BrazilMac method. I boot it using vista boot manager via chain0 method from first hard drive. I want to install EFI to update to 10.5.2. I followed the instructions in Readme.txt file of efi (v.8.0) package but looks like it didn't installed or not working (executing ioreg -p IODeviceTree -b -n efi | grep "efi" -C 4 shows nothing). I've triple-checked everything and found no any things which I've done wrong. Please help.

 

My config: AMD SSE3, nForce4 Ultra mb, SATA drive (via medevil drivers).

Thanks
