Black screen after DSMOS has arrived

[student1242]

hi @all,

I created the USB-stick installer thing with unibeast and the mavericks install app from the mac app store.
When i try booting it in verbose (and cpus=1), i get the following lines and the screen blacks out immediately (it took quite a few tries to shoot this pic ).
my Notebook is a HP pavillion g6 2348sg with a i7-3632QM, the Intel HM76 Express chipset and dual graphics with the AMD Radeon HD 7670M and some intel Chipset (HD 4000).
I assume it is some problem with the graphics, so i tried GraphicsEnabler= Yes/No but neither worked.
Additional, the screen totally shuts off, it is not "black" it is "off"

Any ideas how to get the screen bright again?

Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)

System: manufacturer/model
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
System: HP ProBook 4540s
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx). For a laptop, these details are important and affect critical installation procedures.

Try with:
IGPEnabler=01660003 dart=0 -v

If that doesn't work, remove all Radeon kexts (AMD*, ATI*) and try:
IGPEnabler=01660003 dart=0 -v -f

Try with:
IGPEnabler=01660003 dart=0 -v

Totally did the trick!

Now i installed Mavericks on a spare HDD but when I boot the installed OSX with -v cpus=1 IGPEnabler=01660003 dart=0 I get the following screen and it freezes

Again, any ideas?

Remove Radeon kexts (AMD*, ATI*). Instead of cpus=1 install KernelPatcher module from Chameleon.

Might be a silly question, I'm a total noob to the mac world

How do i actually remove kexts and how do i install this kernel patcher ?

Kexts are in /System/Library/Extensions.

The kernel patcher module can be installed via the Chameleon installer or Chameleon Wizard.

Okay, and how do I access them and install a bootloader patch when it doesn't even boot?
Can i do this from the bootable installer stick?

You can do it in Terminal from the USB/OS X installer. You could also try safe mode... (-x)

Use cpus=1 until you can install kernel patcher.
