This is a guide for AMD 790GX Based Mobo's i'm using a ECS A790GXM-AD3 Motherboard.

Based Off Of This Great Guide

[AMD] Installing Snow Leopard 10A432 on AMD System, Running Snow Leopard On AMD n Non Vanilla Kernel User

 

Step One Get All of the files.

• Kernel for install: Modbin Test 7 Download
  
• Kernel after updating to 10.6.2:Snow Leopard kernel by qoopz/nawcom 10.2 Download
  
• Bootloader: Chameleon RC3 Installer By Dr. Hurt Download
  
• Required Kext's:
  
  • dsmos.kext - required to decrypt encrypted binaries
    
  • NullCPUPowerManagement.kext - attaches in place of the real AppleIntelCPUPowerManagement which doesn't work right on PCs (kernel panic, cpu running hot)
    
  • OpenHaltRestart.kext - very simple kext that makes reboot and shutdown work on PCs
    
  • PlatformUUID.kext - sets the platform UUID so that you have a uniform UUID from the very start of the boot.. this UUID is used in your preferences files (among other things) and I think it is important for a clean install to have this right from the first boot.
    

  Download

  [*]And of course a retail dvd (i used the boxed edition)

Step Two:

• Install Leopard (10.5) if you don't have a working install
  
• Make sure you format HFS+ Journaled GUID Partition Scheme.
  

Step Three:

• In Leopard Make a Partition for Snow Leopard, in my case its named Snow Leopard
  
• Also get the UUID
  
• Right Click On You Snow Leopard partition and hit info and find UUID and write it down or copy it somewhere safe.
  

Step Four:

• Run the Chameleon RC3 Installer by Dr. Hurt and install it to whatever partition you want.
  
• Then in the partition you installed Chameleon Open the Extra Folder and make a folder named "Extensions".
  then unarchive the kext's in the download into that folder.
  
• In the "PlatformUUID.kext" Right click and select show package and open the folder and edit "Info.plist" and where you see "00000000-0000-1000-8000-000000000000" Put the UUID you put earlier.
  
• Also in the Extra Folder make a file called smbios.plist and put this
  

  <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
     <key>SMbiosvendor</key>
     <string>Apple Inc.</string>
     <key>SMbiosversion</key>
     <string>MP21.88Z.005C.B01.0608221120</string>
     <key>SMbiosdate</key>
     <string>04/01/2008</string>
     <key>SMboardmanufacturer</key>
     <string>Apple Computer, Inc.</string>
     <key>SMboardproduct</key>
     <string>Mac-F4208DC8</string>
     <key>SMfamily</key>
     <string>MacPro</string>
     <key>SMmanufacturer</key>
     <string>Apple Inc.</string>
     <key>SMproductname</key>
     <string>MacPro2,1</string>
     <key>SMserial</key>
     <string>W88033AKY51</string>
     <key>SMsystemversion</key>
     <string>1.0</string>
     <key>SMUUID</key>
     <string>0000000-0000-1000-8000-000000000000</string>
     <key>SMmemtype</key>
     <string>19</string>
     <key>SMmemspeed</key>
     <string>800</string>
     <key>SMmemmanufacter</key>
     <string>Apple Computer Inc.</string>
     <key>SMmemserial</key>
     <string>100000000</string>
     <key>SMmempart</key>
     <string>1</string>
    <!--
     <key>SMexternalclock</key>
     <string></string>
     <key>SMmaximalclock</key>
     <string></string>
    -->
    </dict>
    </plist>

  
  and where you see "00000000-0000-1000-8000-000000000000" Put the UUID you put earlier.
  

Step Five:

• Insert Your Snow Leopard Install DVD in to your dvd-rom drive.
  
• If you cant view hidden files install onyx and go to preferences and then hit finder and then check the option to show hidden files/ folders.
  
• Then navigate to System/Installation/Packages
  
• Then Run OSInstall.mpkg
  
• Select Your Snow Leopard Partition and hit customize select anything you want except the printer drivers deselect those they cause the install to fail on some systems.
  
• Then Let It install
  

Step Six:

• Copy the modbin kernel to the root of the install partition naming it mach_kernel
  

Step Seven:

• It's Finally time to boot into Snow Leopard reboot your PC and in Chameleon put -v -x arch=i386 just to make sure it works.
  
• If it Hangs / Kernel Panics Post here and i will see if i can help.
  

Step Eight:

• Update to 10.6.2
  
• Then copy the kernel from qoopz/nawcom to the root of your snow leopard partition naming it mach_kernel replacing the other modbin kernel

I would love to do this, the problem however is:

I can't install leopard. I have tried ideneb didn't work while some people did actually ran it.

[m3a790gxh]

Hi,

 

I read alot here and there. And i am very happy to see a guide for a motherboard which is alike to mine. I have a m3a790gxh from Asrock. Well, i know for installing Snow Leopard that i need a running osx system. I have bought my Snow Leopard DVD and now i wanted to know which distribution i could download to start getting my Leopard first of all.

 

I tried iDeneb 1.6 - no luck with booting

now i will try with iPC 10.5.6

 

my question is: which distribution did u use for your board? And is it possible to build from a loaded distribution one where i can implement my mach_kernel (test7) so i can boot ?

 

thx in advance

 

 

EDIT:

 

iDeneb 1.4 WORKING

internal GraphicCard 1400x1000 something. But NOT WORKING right

Onboard Sound ALC890 NOT WORKING

 

 

Will try the next days to install Snow leopard on other partition

[m3a790gxh]

Hi Andrew,

 

i did try Snow Leopard yesterday and today but i get a kernel panic.

 

Did exectly all the steps how u wrote it down, but no luck.

 

 

EDIT: well in your guide you forgot mentioning the modbin kernel. I copied the kernel into the root of installing partition and renamed it to boot after installing the Chameloeon 2 rc3.

 

I thought that now it would work, but no. No Luck. After 70% i get kernel panic

 

any ideas?

 

chau

[andrewq2]

This is what i used on my board

• Distro
  
  • i_ATKOSv7 10.5.7
    

  [*]Kernel

  • 10.5.5
    

Hopefully this will help.

 

Andrew

 

I would love to do this, the problem however is:

I can't install leopard. I have tried ideneb didn't work while some people did actually ran it.

I used iATKOSv7 10.5.7 just look in the usual places

I used this guide on a Biostar TA790GX A3+ board. I'm running snow leopard, but have 2 problems. One is that my onboard LAN doesn't work, and I am using a PCI network card thats slow as {censored}, and my video card (4650) is not supported. But otherwise, great guide!

[ebgamer123]

Would I be able to install this on an external harddrive from a MacBook? And use it on my system as a dual boot with windows 7 if I boot from the external harddrive to run chameleon?

In case someone wants to install Snow Leopard to a MBR partition change the OSinstall.mpkg with the one on my attachment.

 

Just make sure you have your OSX86 Retail DVD stored on your GUID partitioned usb drive (8gb at least).

 

Retail OSinstall.mpkg for MBR

 

Awesome guide.
