Intel CPUManagement Issues in Snow Leopard installer

[21Winters]

Hi all,

I am currently trying to build a Snow Leopard hackintosh and I am having some issues with getting the installer to boot correctly. I have my BIOS and everything tweaked with all the correct CPU power settings and such, and I can get the installer to start (at least get text scrolling down the screen and stuff) with -v and -x options. However, after about a minute, the installer throws a panic message and gives the following errors (not in order):

 

BootCache: hit rate below threshold (90 hits on 3003 lookups)

panic(cpu 0 caller 0xffffff7f0065e6a3) "CPU 1 has no HPET assigned to it"@/SourceCache/AppleIntelCPUPowerManagement/CPUPowerManagement-90/pmThread.c: 164

Debugger called: <panic>

Kernel Extensions in backtrace (with dependencies):

BSD process name corresponding to current thread: kernel_task



Mac OS version:

--------------------------

 

I am thinking that my processor may not be directly supported by one of the driver files (.plist, DSDT, .kext) that come with the OS X Snow Leopard DVD. I think the main issue is the installer not being able to properly figure out how many CPU's are present. It appears that it was trying to "ping" them, and that most of the errors are occuring in the BootCache section. As you have probably already figured out, I am very new to hacking OS X, but I do have previous computer expirience. Please let me know what I need in order to fix this problem. Maybe I need to create a custom .plist file or DSDT for the installer to boot properly. Also, I can post photos of the boot process if needed.

P.S. If you are having the same trouble with your Intel CPU, please reply to this topic post, maybe we can figure this out.

 

 

 

System Specs:

 

~ Intel Core 2 Duo E8400 @ 3.00 GHz

 

~ 4 GB RAM

 

~ PNY Nvidia 9800 GT (1 GB GRAM)

 

~ Abit IP32 PRO Intel motherboard

 

~ SATA Western Digital HD

 

~ Used a few different EFI boot methods, all throw similar error(s) [Dr. Hurt's EFI, pure Chameleon, Empire EFI, Stella's Snow Magic, ...]

 

~ I want to keep a vanilla kernel *if* possible

 

~ Fully legit, Apple OS X Snow Leopard install DVD version 10.6

 

- Thank you!

Neither Snow Leopard nor any of the boot CDs you're using come with a DSDT, DSDT is an ACPI table which is part of your motherboard BIOS:

https://wiki.archlinux.org/index.php/DSDT

 

This is a motherboard issue. Your CPU is 100% compatible and you're good to run the vanilla kernel.

http://en.wikipedia.org/wiki/High_Precision_Event_Timer

 

Make sure ACPI 2.0, ACPI APIC and all advanced CPU features (except CPUID Limit) is enabled in your motherboard BIOS. Look for a HPET setting somewhere, if you find it, try changing it and see what happens. Some motherboards have a 32/64-bit HPET setting in the BIOS.

 

As a last resort try disabling devices that are not strictly necessary during the installation process, like sound, serial/parallel/firewire/game ports etc etc.

 

If the above doesn't help, find (use forum search) and add disabler.kext or nullAppleIntelCPUPowerManagement.kext to your boot CD, this should allow you to bypass the HPET error and continue to the installer.

 

If you don't know how to do this, try to find a guide that explains how to make a Chameleon boot CD (there are plenty of those around) this will teach you how to take one apart and find out what goes where so that you can do whatever you have to do to it.

 

Once the system is installed fix the issue by patching Device (HPET) in your DSDT. Use the forum search to find out more.

 

The bootcache errors don't have anything to do with your CPU, those can be ignored. They will go away once you're done installing.
