Kernel Panic on Startup "unable to find driver for this platform: \"ACPI\".../IOPlatformExpert.cpp:

Hey Guys,
I got a problem with my hackintosh. I had a succesfully installed hackintosh on my pc, but then i made a terrible experiment and now i know the mention of "never touch a running System". On my pc are two hackintoshs installed, the first one which is now ****ed up and the second one which is still running. Because of some issues on the first hackintosh, which the other hasn´t , i copied all the kext from the first one to another place on my Volume and put the kexts from the second one to the S/L/E of the first one, repaired permissions and emptied the cache then i tried to start and what a surprise Kernel Panic. I just wanted to test it, because i thought everything will be working fine if i put the old Extensions back and repair permissions. But this Fails!

Now i get this Kp:

Panic(cpu 0 caller 0x563ebd): "unable to find driver for this platform: \"ACPI\".n"@/SourceCache/xnu/xnu-1504.15.2/iokit/Kernel
/IOPlatformExpert.cpp:1378
Debugger called: <panic>

Booting with -v works.

My specs Are:
CPU: Intel Pentium Dual Core E5200 @ 2.50 GHz
Mainboard: Msi p43 neo
Video Card: Ati Radeon 4830

Is there any chance to get my System working, without a completly new install?

Greetings

Not sure if you have both hack volumes screwed up from your write up but
if you trying to turn off ACPI suggest you use these boot switches when you boot
test these on each volume.

-x -v -f acpi=off PCIRootUID=1 GraphicsEnabler=No

what does what :
-x is safe mode like windows
-v is the text mode debugger
-f is the clear cache mode
acpi-off is the turn off acpi functions
PCIRootUID=1 is the video source internal or external
GraphicsEnabler=No is the restrict gfx to basic mode 1024x768

 

As i said, one hackintosh is working more or less correctly but it works. Its an old Installation i forgot to deinstall. My main hackintosh got the KP.
So i booted succesfully with this flags. My question is, whats the cause of these flags? The safe mode is already working. Now do you have any idea how i can get my main System working on the normal mode? I mean i got all the kexts which worked in this system nearly perfect.

Thanks man for your reply!

Glad that the string worked for you

Now all you have to do is to isolate what the problem is

suggest you start by shortening the string - by removing items from the string

so what happens when you do not use the PCIRootUID or the GraphicsEnabler

do these one and a time to see what happens

Most likely you will need to run MulItBeast on the system volume that is having the problem.

Also in MultiBeast you need to run the System Utilities for permissions and file rights -
Do this asap

moving kexts helter skelter rests the rightes from what they were to what Your user permissions rights are and this is a problem.


If you get to the one w the ACPI=off and this does not work its the power management that is the problem

Test and repeat as required.

 

So now i tried to boot with theese flags:
-x -v -f acpi=off PCIRootUID=1 GraphicsEnabler=No
-x -v -f acpi=off PCIRootUID=1
-x -v -f acpi=off
-x -v -f
-x -v

The system boots fine with all of theese.

I already repaired permission with Multibeast. So whats the problem ? Did i do the right, or am i´m doing it wrong ?

 

Killer...

I think the permissions was the problem and your working

I see you down to two switches

the next selection would be to drop the -x to remove safe mode ( if your still using it)

and use only the -v

then if that works drop the -v and use NO switches and see if your still in the Ball Game.

 

Ok sorry for my missunderstaning and thanks for your reply!

If i leave -x it always stucks at this:



Leaving the -v theres no KP but it hangs on this:



Greetings

 

Is there anything on the non-working drive that is not on the working one? If yes, boot to working drive and back up those items.
Boot the working system and make a time machine backup of it. Then you can do a partial restore of the backup to the non-working one, selecting option to restore files you select only.

 

Hey Going bald.
I think this is more work than reinstall macosx.
Ok i have to admit i have already spent more time on that as the the reinstallation would need. But this was a perfect working System and i dont want to give it up.
There must be another way. I have all the kexts which worked together nearly fine, so how can i solve this?

I tried to install the kexts with kext utility, kext helper, kext wizard but if i go to the /S /L /E it also tells me that they aren´t installed correctlly.

it looks like this

this kext is from National Instruments something to do w labview and a NA GPIB card - you have this in the Hack.

If this was installed onto the orginal

then I am still thinking its permissions here is an article on how to check.
