I boot fine from my USB boot-132, however, using this new method causes my system to lock up when it is nearly ready to start the aqua interface.

I did both, with the exact same results both times. I'm wondering if the alternate kexts are even being loaded. I triple checked my directory structure and everything is fine.


Update:
I have a copy of leopard 10.5.0 on a small 8GB partition on my second HD. I can use this boot method to boot that partition just fine. Further more, the alternate kexts are being loaded since I have PS2 support. My primary partition has 10.5.5, so something is definately broken here.

Mine freezes at the Apple Logo screen also.

Here is error with -v:

With -v -f: it freezes at the mDNSresponder line this is a few up from bottom.

It works fine with my USB or CD Boot-132.

Could it be a problem with the Stage-2 as noted in the post here:

Its the very last line of first post.

I am using 10.5.5 also.

I have 2 drives which were installed from the retail dvd - one internal ata and the other external usb. Both are getting the same result as you are seeing here.

Lucky for me, I also have a third partition which can still be booted from the boot-132 iso.

GPTEFIBoot is a similar but unrelated project, so I cant really comment on it.

Did you place System.kext on your EFI partition?

I'm pretty sure you need the correct version of System.kext in the /System/Booter/Extensions folder on the EFI partition. Give it a try.

What kind of hardware are you using? Core cpu or pre-Core? Which kernel?

bladerunner can u try this also please? if u are using a 9.4.0 kernel (10.5.4) then please use the 9.4.0 / 10.5.4 System.kext in your /System/Booter/Extensions folder on the EFI partition.

to mount:

sudo -s
mkdir /Volumes/EFI
mount_hfs /dev/diskXs1 /Volumes/EFI

to unmount once finished:

sudo -s
umount -f /Volumes/EFI
rm -rf /Volumes/EFI


please also make sure u copy the kexts as root (sudo -s). otherwise permissions errors may be a problem.

I do not think I have the system.kext. I will try when I get home. I used all the kexts from my initrd.img off my boot CD.

I can still boot with the boot-132 no problem.

I am using a Gigabyte GA-EP45-DS4. With a Q9550 CPU.

yay! first success story.

yes, EFI strings will NOT work, as the stage2 booter is NOT Chameleon, but a fork of dfe's bootloader. means you have to go back to injectors or whatever, or wait for the next Chameleon... :)

Teh EFI strings may be what is causing the hang on my systems. I have been using them in place of the nvinject kect. I am working on changing that not. Results later :)

With Efi strings the system hangs before the GUI, with Nvkush & Nvinject i only have resolutions, with Natit full QE/CI (10.5.5).

BTW is there any big difference between EFI strings and injectors ?


i have better results in OpenGL Extensions Viewer tests with natit than nvinject , nvkush or efistrings
