lestatx86 Posted March 14, 2008 Share Posted March 14, 2008 Hi! I managed to install Kalyway 10.5.1 on my machine (P965 chipset, Core2Duo, SATA HDDs, GF7950GT), even though some minor issues remain. After the first DVD boot I had bootmanager trouble and needed to reconfigure a lot of stuff, and needed to call the "startupfiledisk" command myself. There I could choose between boot0 boot1h, boot1u and efi drivers. I chose boot1h, because that was most common in all tutorials I read. I am now wondering, what did I miss in the kalyway installer? I figure from some tutorials that there should've been an intermediate step where I could choose that through menus? What's the difference with the EFI bootloader vs. MBR/GUID and those boot0/chain0 methods? Is the EFI_v8 stuff in some way preferrable?

lestatx86 Posted March 15, 2008 Author Share Posted March 15, 2008 Hi! I did browse through netkas.org a lot. As much as I appreciate his work, I hate his writing skills. His tutorials make no sense at all to me, they expect you to already know everything. What I need to know: - Do I Need that EFI stuff? Is it required for 10.5.2? - Is EFI a bootloader? Or a partition type? Or does it flash the ROM of my graphics card / BIOS? - Can I run MacOS and Vista (without re-installing vista) side by side with that EFI method? - Can I install the EFI bootloader(?) using the startupdisktool on an existing Leopard installation, or do I need to completely reinstall? I'd really appreciate a link or small text that explains the basics of what EFI and GUID is, and how they all play together with MBR and partitions. :-) Link to comment https://www.insanelymac.com/forum/topic/93529-efi-vs-guid-vs-mbr-vs-wtf/#findComment-668006 Share on other sites More sharing options...
Superhai Posted March 15, 2008 Share Posted March 15, 2008 Shortly, you don't need the "EFI" bootloader. But it does in most cases make your hackintosh work better and I recommend it. You don't need GPT (GUID) and I would recommend you choose MBR right now. You should note this as I think this is where the confusion arise. EFI is not a bootloader it is a new style of implementing "BIOS". The "EFI" bootloader is just addon to the darwin bootloader (for legacy BIOS PCs without EFI) to be able to pass some of the information that a real mac would get from its EFI. Answers to your questions: 1 No, no. 2 Yes/no, no, no. 3 Yes 4 Yes, no new install required. But some settings in BIOS is might be required and change in your hackintosh install might also be required. Your really should read through netkas and others information once more to see the benefits, the wormholes and what system is required for support.

DaveGee Posted March 15, 2008 Share Posted March 15, 2008 Well I'm very new to pc efi myself but not to getting os x running on generic hardware... So take this for what it's worth. What does efi do (for some) - Your mobo / chipset matters a great deal here I think! In short with pc efi I'm VERY impressed, no more hunt down the 10.5.1x 'Bluto kernel' or the 'Popeye release' of the 10.5.1a-intel DVD installer or the 'Olive-oil' 10.5.2z installer patcher customizer or the 'Whimpy Burger' system massager and stabilizer platform... System Specs: - An Intel (bad axe 2) motherboard based computer - C2D CPU - 2GB of ram - 2 sata hard drives - 1 dvd drive - 7600GT video card - Case, power supply, keyboard, mouse and monitor... Note: I did have to have a bootable OS X drive to do this procedure!!! I had a 'heavily modified 10.5 dvd installer' (not naming names) that I used to install a working (all be it far far far from clean) 10.5 bootable HD after that I used to start out on my mission to have as clean of an install as possible (without giving up speed or stability). Here were the basic steps I had to take. I guess I could have done all of the prep work with a 10.4 based install too... I simply needed something that had the ability to run the installer package off a standard RETAIL 10.5.0 dvd. 0 - Drive prep work to the OTHER drive (pc efi, formatting and making active) 1 - MANUALLY (launch from the command line) install of the retail 10.5.0 DVD to that OTHER drive (no reboot yet) 2 - Added 2 kexts (one I cant remember the name) and the other is NVinject - fixed permissions then (rebooted to that OTHER drive) From this point I am only working and booting from the OTHER drive using a 99.9% unmodified 'Apple OS X 10.5' install! 3 - Edited (pasted a few lines) to the com.apple.Boot.plist file this fixed errors with Time Machine and assorted console errors. (rebooted again) 4 - Download and MANUALLY install the 10.5.2 combo-updater (from Apple) doing some fancy 'cleanup work' while the 10.5.2 standalone installer runs. The cleanup work is VERY important!! (then reboot) 5 - Download and run the v1.16 version (last version that seems to work with my mobo - YMWV) of the AppleHDA Patcher (the patcher can be found here in its own form area) Note: I'm now reading that I could even get rid of that NVinject with some further changes to the com.apple.Boot.plist file.... I have to look more into it tho! Given the state of installing OS X on pc hardware in the days of 10.4.x and now I'm very very very impressed! Wow thats a lot to say to answer a simple 'what is pc efi' but I as you can see I'm really quite exited about it all... EFI - In short (too late) pc efi is really just a boot loader that more closely mimics the way Apple boots their Intel based systems and in so doing allows for a DRASTICALLY cleaner install of the OS. Again your mobo matters a great deal here I think! I feel lucky having chose the bad axe 2 mobo since it seems to be really supported well. Others can chime in WRT their experiences with efi and their specific mobo. GUID and MBR - two different ways to partition a HD -- Not exactly sure what the difference is but it would seem (from my readings) that GUID is (or was?) a better way (only way?) to go if you wanted to use the pc efi approach to installing and booting OS X.

lestatx86 Posted March 15, 2008 Author Share Posted March 15, 2008 Hi Superhai! You just made my day, I can see the sun through the clouds. To apply the EFI_8 bootloader addition, do I need to use the startupdisk tool? If so, is there a command line option to nidicate that I want EFI-MBR instead of EFI-GUID, or will the tool have an interactive prompt? I'm just asking before I screw anything up. Many thanks, Lestat Link to comment https://www.insanelymac.com/forum/topic/93529-efi-vs-guid-vs-mbr-vs-wtf/#findComment-668109 Share on other sites More sharing options...

It boots whatever you have formatted your harddisk as. Just follow the instruction in the PCEFI8 package. And yes use startupdisktool.
