Conroe Mac Posted December 23, 2007 Share Posted December 23, 2007 After about five leopard efi installs, I still haven't been able to get one to boot correctly. I have been thinking the problem is the way the motherboard is set up, but now I am thinking the problem is actually my processor which is a pentium D. Anyone out there running a Pentium D with the vanilla kernel and EFI emulation? I was able to boot my efi installation, but only by booting darwin from the install disc. Booting darwin from the hard drive results in a hard restart after selecting the partition to boot.

RobD Posted December 23, 2007 Share Posted December 23, 2007 Vanilla was a no go for me, I've the same D 805.

eragon Posted December 23, 2007 Share Posted December 23, 2007 It has to be a Core 2 Duo CPU to use EFI, that's why it wont boot. Link to comment https://www.insanelymac.com/forum/topic/77491-anyone-running-efivanilla-and-pentium-d/#findComment-548484 Share on other sites More sharing options...
Hagar Posted December 23, 2007 Share Posted December 23, 2007 Erm.. lets get this straight.. pc-efi (often mistakenly called "EFI") works with all intel & clearly some AMD cpus. Using the "vanilla" (plain Apple unmodified) kernel requires at least a core-series cpu, probably a core2 for all practical purposes. *As well as* the pc-efi bootloader. GUID partitions can be used with pc-efi regardless of kernel choice, MBR partitions can be used with pc-efi or standard darwin bootloader.
