Freeze on booting from hard drive, boot disk just fine

[DCKing]

Hello all,

 

First of all, thanks to this great community that made tutorials to show to install OSx86 in the first place.

 

OSx86 10.6.7 is now running fine on my PC (AMD PhII X4, Asrock 880GMH, R4890HD) without any annoyances. To boot it, I use the PirateEFI-X AMD edition 0.3 and it boots fine 90% of the time (sometimes a kernel panic occurs, but only during boot). The trouble is with trying to boot this installation from a hard drive.

 

The PC has Windows and Ubuntu installed as well, and it has a GRUB2 bootloader. I tried to make OSx86 install using that bootloader using this post which seems to have worked fine. When I select the OS X option in the menu, it actually starts booting and I can load up the Chameleon F8 menu for kernel options.

 

If I try to boot OS X with Chameleon with out any options, it hangs at the Apple logo. When I boot using -v, it quickly prints half a screen of (seemingly regular) diagnostic messages and then the screen goes to black. When I boot using -v -f -x it goes through the usuals kext reloading procedure, but after that's done it still goes to a black screen. I've tried this with Chameleon 2 RC5 r699 and r753 and Chameleon 2 RC1, all with the same result. My hard drive is in AHCI mode, and it uses an MBR.

 

So here's what I have: a machine that is perfectly capable of running of OS X, but a boot procedure that goes wrong. Does anybody have any idea what I can do to fix this?

 

Note that the kernel panics that sometimes occur when using PirateEFI occur at a much later stage as when the booting from hard drive fails, so they're probably unrelated.

 

Thanks in advance!
