Hi I am new here but have several questions. I installed Zeph rev. 1 and then used mach_sleep (sleep kernel from IRC) because I need the Leo to sleep. 10.5.1 worked like a charm. Anyway I used the Vanilla 10.5.2 update (with Installer.app don't use Pacifist, removed AppleIntelCPU.., nano Scripts/1) then I patched it with Marvin's Util and booted again with mach_sleep (which is 9.1.0). Now sleep dosen't work. I had pc efi installed with original Zeph rev.1 but I am not sure if it works or not since I have a 2 min. wait with QE/CI Geforce 7300 GT (with flashed bios for 512 mb) after the 10.5.2 update. I can run the universal speedstep 9.2.0 (from IRC) kernel but does this mean that I have efi working or not. When you talk about 9.2.0 are you talking about a vanilla 9.2.0?

Zeph or Eddie: is there any way to test pc efi functionality on an AMD machine. I have an Intel machine with PC EFI and I use Vanilla kexts there but on AMD can I use vanilla kexts to avoid the 2 minute wait on boot up? The Graphic Update after 10.5.2 update gave me NDARasman and Geforce kext kernel panic (Replaced these 2 kexts with Zeph NVUniversal.installer).

About the endless reboots above it smells to me like a vanilla kernel rebooting the machine.
About uninstalling pc efi, google pc efi I think the command was something like ./startiupfiletoll /dev/xxxx ./boot_i386 or ./i386 ( http://www.digitmemo.com/articles/734/howto-install-efi-patch-and-enable-vanilla-os-x-kernel-in-hackintosh/ )
