so since the v6, there's no apple logo on boot, sorry :)

 

since vanilla seems not to need DSDT, you just need to install version 5.1 to get the grey apple. that's what I did :whistle:

EDIT: after further testing, it would appear there is a hard 4k limit on the com.apple.Boot.plist file, at least how I'm loading it. Dunno if this has to do with the fact that I'm also loading DSDT.aml. So for those of you getting the error "Error parsing plist file" and you're using this method, check to make sure it's under 4096 bytes.

 

 

 

In the second line, where it says //Apple Computer//, try changing it to just //Apple//. I know that changed from Tiger to Leopard, so that's a slight possibility. I'm having the same problem, but I think it has to do with my setup and use of GRUB more than anything.

 

Many thanks :P

Unfortunately if I put the efi string of my ATI HD2600 XT inside com.apple.Boot.plist, it exceed 4096 bytes dimensions..

 

Munky, there's something can I do to get it working?

Well I got say I LOVE IT!!! :) I got my ASUS RIIE up and running and fast as hell! I'll post some marks later. Right now I got it up to 4GHz. Your guide is Awesome!

Thank you to jimmydigital00, BladeRunner, Ripperss & TheHAWKs

Big Thanks to MJ, munky & ~pcwiz!! :borg:;)B)

Hi again bladerunner - after my last post I've learned a lot. I now have a question about dual booting which, although it's not strictly related to this thread, might have ramifications for others who use Munky's EFI method. My machine is a pre-core Pentium 4 running 3 GHz, with 2 x SATA drives.

 

The first drive contains Win XP and Data on 2 separate partitions. When I set the BIOS boot sequence to start on this drive, Win XP boots and operates normally.

 

The second drive contains the EFI partition(1) with Munky's boot files, kernels and kexts, and your modified boot.plist; partition (2) with Leopard 10.5 installed from the retail DVD, and a Spare partition(3). When I set the BIOS boot sequence to start on this second drive, 10.5 boots and starts normally with no further intervention from the keyboard. :) .

 

Not satisfied with entering the BIOS boot sequencer at every startup, I attempted to use the Chain0 method to insert a selection menu on the Windows Bootloader screen to allow choice of Win XP or Leopard 10.5. So I downloaded and unzipped Chain0, installed it at root on the Win XP partition of drive 1. The Win bootloader now displays the selection menu, and if I choose Win XP, that OS system boots and operates normally. However if I select Leopard 10.5, I get "Chain booting error" and no further action.

 

Researching this error on Google/Wiki I discovered that Chain0 looks for the OSX boot sector, and if successful, transfers control to its bootloader. To cut a long story short, Chain0 looks for "AA55" as the last 2 bytes in the OSX bootloader. Following the method listed in one of the wikis, I confirmed that the last 2 bytes in Block 1 on my EFI partition were indeed AA55.

 

So now I'm stumped, and in pretty unfamiliar territory. Is Munky's EFI booting system compatible with Chain0? Do you or anyone else understand more about this dual-booting method, and how I might be able to get seamless booting of 10.5? Alternatively, is there a way that the Darwin bootloader can look at the 2 drives, and let me choose Win XP or 10.5. (BTW if I press enter during Darwin boot, a menu appears, giving me a choice of Leopard 10.5 or Spare - the third partition of the Leopard drive, but not the Win XP drive).

 

Any thoughts would be much appreciated.

This all sounds very good. However, i am unable to boot the vanillia disk (hangs at 2621 headers, 2621 headers). I installed iPC 10.5.6 instead, with patch dsdt and dsdt function in chameleon. I am also currently using a GUID structured hard drive. Can I still make this work?

Thanks anyway BR. I'll keep looking, but if anyone else has any suggestions on dual booting, either XP/Leopard or Leopard XP, I'd love to hear them.

Mac OS X RETAIL DVD:

 

10.5.4

 

Method of installation:

 

Munky's method verbatim as listed top of this thread.

 

 

Results:

 

I am able to boot to Darwin, but upon pressing enter I get the dreaded "You must shutdown your comptuer" screen.

 

Notes on my installation:

 

When I boot to Darwin, I am able to do so without any boot CD, i.e. it is booting from the hard drive.

 

I have NOT added ANY kexts AT ALL at this point. (I don't know what I SHOULD add or where to get files that may be needed for my machine; hopfully this is my only problem and I just need someone to lead the way.

 

Primary goals / reasons for wanting to get this to work:

 

1) Need a machine I can use FinalCut Pro on (I'm in Hollywood :wacko:

 

2) That being said, I MUST be able to get CI & QE working. (My nVidia device ID: 0398) My video has 512MB but only 256MB is seen. Anyone who can help me to get all of this working would be worthy and eligible to be added to my Will. = )

 

3) Help getting any (all?) hardware devices on my machine working.

 

Following is a screen shot showing current problems after using -v to boot:

Hi,

 

tried to install retail DVD on sony vaio z21wn...

first, was no problem, it was running (without ethernet, audio, keyboard)

I use a usb keyboard which works and it is installed on a external usb drive...

I tried following your guide here but then something have destroyed something :)

What was different to your guide: as trying to mark the EFI partition as active, it says it needs exclusivly write access, and do this after reboot...

since then... "still waiting for root device"

What to do now?

I am not able to boot anymore into the macOS... can i recover from this situation?

(no .kext installed up to now)...

 

cheers,

bigcheese

 

post-363992-1233425172_thumb.jpg

 

ok - update:

reinstalled everything - without marking partition as active - on my vaio i can boot from it...

but it always says "Package 0 didn't get an HPET"...

even with -f or -x after a while the wheel with the stripes rotates in 7 sec one tick further and nothing more happens...

 

update2:

taking the idea from Mammoth (copying the .kext files of initrd.img from the bootcd) - now i am able to boot in osx from harddisk...

perhaps munky should mentioned this in the 1st entry of the thread, because it was the same on my machine? - or have we missed something ;) ?

now going further with .kext ... :)

Have you tried -v -f -x ???

 

Thank you so much for your reply. I have been sitting here litterally ALL DAY trying to get this to work. I finally got past the initial problem by copying the .kext files out of the initrd.img file on the boot CD and puting them in /System/Library/Extensions.

 

Now I'm fighting to get QE/CI working... aarrrgggg! I can't believe it is this dificult to get all of this to work.

 

I'm trying to use the NVinjectGo.kext from http://nvinject.free.fr but I'm not making any progess. If anyone can help.....

What a wasted weekend....

Hello all. :) After a succesful install of iPC I finally dared to try a retail install the EFI way. Everything worked following munky's phases 0 to 5. I could nicely boot into Leopard 10.5.1. Only problems left were my NVidia8800GT 1Gb and my audio.

I downloaded EFI Studio and created an EFI String for a 8800GT 512Mb (as no 1Gb was in this list). I also added to com.apple.Boot.plist. Rebooted.... and now I get the Kernel panic! Cant boot into Leopard anymore ;(

Whats wrong? I did the same things as I was used to with iPC install...thats what caused it?

 

Should I have added the string with the EFI Studio tool to the com.apple.boot.plist thats on the EFI partition??

Can I still solve this without a complete re install?

How can I also make my ALC883 sound working? Could I use the Taruga patcher or does this also screw up the install?

 

end of the report after booting with -v:

kextd[70]: loaded version 1.6.0. of com.apple.iokit.IONetworking Family differs from requested version 1.6.0 (UUIDs differ)

kextd[70]: a link/load error occured for kernel extension /System/L/E/IOFireWireIP.kext

 

Thank you all for any help!!! ;)

http://nvinject.free.fr/forums/viewtopic.p...;highlight=7600

 

What really sucks is that I followed this guys advice a year ago... AND GOT IT WORKING! Now, no matter what, I cannot. Is it something to do with the Munky method and EFI? Am I missing something (I MUST be)?

 

(Yes, I have PM him, but have not heard back, and may not as that was a year ago.)

 

 

 

Any other information you need, please ask and it will be provided.

You need the boot0.gpt instead of the regular chain0. Good luck. ;)

You should be ble to avoid a reinstall. Boot into single user mode using "-v -s". When it stops at the command prompt you can follow the on-screen instructions to mount the root. Then, do a cd to the partition with the com.apple.Boot.plist and use the "vi" editor to remove the EFI strings you added.

 

That should allow you to boot back to your system as before.

 

Good luck!

I also don't have QE/CI with Nvinject, or Nvkush, after updating to 10.5.6. Had to install NVDarwin into S/L/E, because none of the work out of the EFI partition. I've used EFI strings on my Geforce'Go 7300, and added them to the com.boot.Apple.plist on the EFI partition, with same results. I have resolution change, but no QE/CI.

 

What can I do to get QE/CI from the EFI partition?

Use ~PcWiz's Universal Installer to fix the video EFI string. If there´s no string listed for your card, choose the custom EFI string option, and it'll make you one. Be sure to go to the UI file tab and choose reinstall EFIGX, before.

For ALC883 modded kext that'll work form the EFI Partition, check HERE

Use ~PcWiz's Universal Installer to fix the video EFI string. If there´s no string listed for your card, choose the custom EFI string option, and it'll make you one. Be sure to go to the UI file tab and choose reinstall EFIGX, before.

For ALC883 modded kext that'll work form the EFI Partition, check HERE

 

It worked for 8800GT 1Gb!!!! Thanks a lot mate! ;p

 

For Audio..why can't I use the Taruga patch method? I followed everything and I do have SOUND now!! A big THANKS to this community..

 

Also Software updating to V10.5.6 worked fine.. Only details in about my Mac are wrong now but that obviously has to do with 10.5.6 since it was correct in 10.5.4

You should be ble to avoid a reinstall. Boot into single user mode using "-v -s". When it stops at the command prompt you can follow the on-screen instructions to mount the root. Then, do a cd to the partition with the com.apple.Boot.plist and use the "vi" editor to remove the EFI strings you added.

 

That should allow you to boot back to your system as before.

 

Good luck!

 

 

Hi Bladerunner thank you for helping me. I did try this but got within nano (after erasing the string) the message: system is read only.. cant write the file. Why is this? Didnt know how to solve it at that time ;(

 

After this I rebooted and got a boot0: error.. then I did a complete re install, again the boot0: error. I figured out it had to do something with my drive setup. I have 1 SATA drive with MACOS on it plus an extra IDE drive connected to the onboard JMicron JMB363 controller. Looking in BIOS in boot priority the SATA wasnt showing up at all (only floppy/cd and the ide drive were there) although in the main BIOS screen it was correctly shown as detected as SATA1! I then took the IDE cable off the IDE drive and looked again in BIOS and now my SATA drive DID show up in the boot priority list (and the IDE had gone out)! Very strange. Now I could boot right into MAC OS. I then re connected the IDE drive and everything was working as it should.

 

Now for my last questions:

I have another SATA drive with XP already on it..I wanna connect it too.. afraid to screw up..should it have the chain0 or other to function correct with one SATA being the MACOSX drive?

 

I also have the problem that sometimes (1 out of 3 boots) I dont have USB keyboard and USB mouse working...any ideas why?
