I have Asus P8Z77V-LX
EVGA- GTX 570

I did install ML and #####. After first restart,it ended up with whitescreen and mouse pointer on the left.

I tried inject PCIRootUID = 0

GraphicsEnabler=No

But no luck

Use these kernel flags at boot time (you won't get the white boot screen due to the -v switch):

npci=0x2000 -v

i always use '-v'
this 'whitescreen' is something different...

-v is just for verbose. did you also give npci=0x2000 at boot prompt ?

also, at what stage does the "whitescreen" show up ? if you have used -v at the time of booting, you should see a bunch of messages. can you post the last message that you see ? or you can also post a pic of the screen before the white screen appears.

What about asking Tonymac about this, since you did not follow the very good guides posted here at Insanely !?!?

a video about nothing...a white screen, would be stupid...I'm not at my first hackintosh...
this is not a matter of flags, or may be a questions of boot ..plist
so...I start booting from a kakewalk usb [defined as z68x-ud3] , is same scenario like with uni-bi-st
tried booting with -v, DSDT=No, -f -x... nothing...when it shoud show the welcome screen, it becomes completelly white, and stays like that

also, in boot.plist...tried graphics enabler = yes / no,
smc...plist...defined imac12,1/12,2/macpro3,1
still nothing

tried also, the power button to put it on sleep, but then it doesn't wake up

completelly disarmed... dunno what to do

If you still get white screen boot with -f -x after removing the mentioned kexts - this will solve your problem.

I would appreciate if you could let me know wether the flags are necessary or not

If it didnt solve the issue, it could be NVCAP hence the white screen.

I've never heard of NVCAP, if your graphics card is what it says it is in your sig then your problem is almost certainly the ATi6xxx kext

well, rockinron_1, I must buy u a drink...
thank u very much bud...as I was suspected, that was the problem...
there wasn'n needed any other flags [use -v anyway]
so, installed, from a kakewalk* usb [used z68x-ud3-b3 predefined mobo]
and after the install, I have reinstalled the ati6000.kext...repaired permissions
I felt necessary to change the dsdt with the one of the tony's specially designed dsdt for my board [z68x-ud5-b3]
--latest chimera
and now, everything seems to be ok**
didn't tested yet the sleep, since my hktosh is still defined as macpro3
I think I will redefine it as imac12,2 and then I'll test the sleep

again, thank you...what's your preferred beer?
:))

*kakewalk manual has a small error
at Step 4 / 4. Select Install to USB [it should be 'Install Kakewalk']... in fact is somehow logic
the installer, then never ends, but, after some couple of minutes u can exit, it has done its job

** audio--ok
ethernet--ok
graphics--ok

sleep... testing-----ok
icloud...testing-----ok
usb3... don't have such a device, but I think is fine


good luck everybody
