tux91 Posted May 18, 2008 Share Posted May 18, 2008 Hi everybody, I have an iATKOS v1.0i up and running right now on a hacked kernel but the 10.5.2 update seems to crash my whole installation. Thus, I'd prefer to have a vanilla kernel. Do I get it right that I have to install EFI emulation in order for the stock kernel to work? I tried to do it before (EFI + Stock Kernel), Leopard installs successfully, but goes into reboot after restarting the machine:( So is my processor (Intel Pentium Dual-Core T2310) incompatible? It is Intel and it supports SSE3, what is the problem? The question: Is there a way to use a vanilla kernel for me? Thank you so much! Compaq Presario C712NR Processor: Intel Pentium Dual-Core T2310 (1.46 GHz, 1MB L2 Cache, 533MHz FSB) Memory: 1GB DDR2 HDD: 80GB Graphics: Intel GMA X3100 Wireless: Broadcom 802.11b/g WLAN Link to comment https://www.insanelymac.com/forum/topic/105472-why-isnt-efi-emulation-working/ Share on other sites More sharing options...
jimmyvau Posted May 18, 2008 Share Posted May 18, 2008 From what I understand, EFI emulation only works on the Core2 family of Intel procs, ie Core2Duo and Core2Quad. The Pentium Dual core is from a completely different family and uses and older design.

Hagar Posted May 18, 2008 Share Posted May 18, 2008 You need to read up, as you have clearly misunderstood a whole bunch of things: "EFI Emulation" ( = pc-efi ) is just a hacked bootloader, if you can boot, its working. The plain apple 10.5.2 update will crash your computer anyhow, you need to remove some files or use a hacked one. ("EFI Emulation allows online system updates" turned out to be wishful thinking) Look it up on intel.com to be sure, but I believe your cpu is just a c2d with less cache. this being the case, you can use either kernel, you do need pc-efi to run the plain apple "vanilla" item.

tux91 Posted May 18, 2008 Author Share Posted May 18, 2008 "EFI Emulation" ( = pc-efi ) is just a hacked bootloader, if you can boot, its working. Are you sure? I didn't install EFI emulation, I installed the OSX86 loader, but i refused to install EFI as i was going to use a hacked kernel anyways. Look it up on intel.com to be sure, but I believe your cpu is just a c2d with less cache. this being the case, you can use either kernel, you do need pc-efi to run the plain apple "vanilla" item. By the way, OSX thinks i have a Core 2 Duo (it is written in the system information). Or does it write it for any processor? Does anybody know why my pc reboots when i try to boot in the system with pc-efi and a vanilla kernel? Does it mean simply incompability of pc-efi with my processor or is there a solution?

Ruud Posted May 18, 2008 Share Posted May 18, 2008 try booting with cpus=1 when using vanilla kernel Link to comment https://www.insanelymac.com/forum/topic/105472-why-isnt-efi-emulation-working/#findComment-750991 Share on other sites More sharing options...
Gujal Posted May 18, 2008 Share Posted May 18, 2008 The main requirement for Vanilla kernel is Intel CPU with EM64T and Execute Disable bit support. Your processor supports both, however you have to check in the BIOS if "Execute Disable" is enabled or is even supported by the BIOS.
