INTRODUCTION

*************************************************************

This guide is:

1. Is focussed on installing and running OS X Lion on a Series 6 or 7 nForce chipset / Intel CPU MOBO with an nVidia graphics card:

simply because I have a 650i nForce chipset + Intel Q6600 CPU MOBO + Inno3D GeForce 9800GT 512MB graphics card........and what works for the 650i should and invariably does work for the 650i Ultra, 680i, 750i, 780i, 790i, and 790i Ultra.....hence my topic tags....

However, in my topic tags, I say 630i only possibly.

This is because my current understanding is that the following nForce chipsets are not fully AHCI compliant and so can be used with imk's 64bit version of the always mentioned nForceATA.kext:

nForce 430/410 (MCP51), nForce 590/570/550/680i/650i/780i/750i/790i (MCP55) and nForce 430/405/400 (MCP61); nForce 560/520 (MCP65) and nForce 630a (MCP67)

Furthermore, the MOBOs using one of these nForce chipsets usually have the BIOS option to set the enable nForce SATA Controller and require SATA RAID to be Enabled (implicitly enabling AHCI mode) even when not running a RAID system, for the NForceATA.kext to work.

In contrast, the following nForce chipsets are/may be fully-AHCI compliant and so do not/may not work with the AppleNForceATA.kext:

nForce 560/520 (MCP65) and nForce 630a (MCP67); nForce 630i/620i/610i (MCP73), nForce 730a/720a/710a (MCP78) and nForce ION (MCP79)

nForce chipsets (MCP65 and higher) support the advanced SATA features in the AHCI standard, such as NCQ etc.

The MOBOs using one of these nForce chipsets usually have the BIOS option to set the nForce SATA Controllers to "AHCI Mode" instead of "IDE Mode".

*************************************************************

As I use an nVidia graphics card, the guide is naturally written from an nVidia perspective; nevertheless, I hope that owners of a Series 6 or 7 nForce chipset / Intel CPU MOBO with an ATI graphics card will use it too because hopefully the method that you have used to get full CI/QE and multi-resolutions in OS X Lion and/or OS X Snow Leopard work the same for OS X Mountain Lion, or work with only convenient minor changes.

*************************************************************

For help with:

1. AMD/ATI graphics cards go here

2. Multiple nVidia graphics card(s) and/or displays go here but go here for setting up your DSDT.aml for AMD/ATI graphics cards

3. For help with mixed multiple AMD/ATI and/or nVidia graphics cards and /or multiple displays, Google is your friend......as are aqua-mac, netkas, and others.......

I also hope that non-nForce chipset + Intel CPU MOBOs also find it interesting and even helpful too.......

I say this because:

{a} Each reader's MOBO brand/model typically has to have its own custom setup for DSDT/audio/networking/video etc.

{b} It is primarily the need for the AppleNForceATA.imk64bit.kext in /Extra/Extensions/ and nForceLAN.0.64.5.kext in /System/Library/ Extensions/, as well not being able to use a SleepEnabler.kext and having issues with sleep that distinguishes nForce chipset + Intel CPU MOBOs from non-nForce chipset + Intel CPU MOBOs rather than the basic procedures for installing OS X.........

2. Split into sections and sub-sections (from post #1 to post #8) for ease of following and adding to....

3. A "live guide" that will evolve with both Mountain Lion and time (with some inevitable typo corrections, additions, deletions etc.).......

So, please read the current online "live" guide before attempting to follow it, even if you had previously followed an earlier version successfully.....

4. Starts with the assumption that you already have OS X Snow Leopard (10.6.6 or later) OR OS X Lion (10.7.2 or later) installed and running in 64bit mode on a Mac or Hack using at least the following 64bit capable kexts in /Extra/Extensions:

AppleNForceATA.imk64bit.kext

EvOreboot.kext or OpenHaltRestart.kext

FakeSMC.kext

NullCPUPowerManagement.kext or Disabler.kext

HOWEVER, if you are currently running OS X Leopard, then see my nForce RETAIL INSTALL GUIDE for Snow Leopard (10.6) on a Series 6 or 7 nForce chipset / Intel CPU MOBO on how to install Snow Leopard.......

Or my nForce OS X Lion (10.7) APP STORE DOWNLOAD INSTALL GUIDE on a Series 6 or 7 nForce chipset / Intel CPU MOBO on how to install Lion.......

While I realise that some of you may have already obtained the OS X Mountain Lion 10.8.0 Installer as a .dmg /.iso image file, my working assumption is that most of you will need to have Snow Leopard installed in order to purchase and download the OS X Mountain Lion 10.8 Installer from the Apple App Store.......

My plea to all readers is:

Remember Apple are a company not a charity and they will do all they can to protect their market share and profits, and if they ever begin to see the OSx86/Hackintosh web fora as a 'serious threat', they may decide to fully 'lock down' OS X......!

SO PLEASE THANK APPLE FOR THEIR FANTASTIC OS AND FOR NOT FULLY LOCKING IT DOWN TO THEIR OWN HARDWARE BY SUPPORTING FURTHER AND FUTURE APPLE R&D ON OS X IF YOU CAN, BY......

[1] BUYING AND DOWNLOADING OS X MOUNTAIN LION 10.8 FROM THE APPLE APP STORE......

[2] IF AND WHEN YOU CAN AFFORD IT, PURCHASING A MAC AND/OR OTHER APPLE PRODUCTS IF THEY CAN DO WHAT YOU NEED THEM TO DO......

*************************************************************

Part A. Enabling Snow Leopard running in 64bit mode or Lion running in default 64bit mode on an nForce MOBO for purchasing and downloading OS X Mountain Lion from the Apple App Store

*************************************************************

According to Apple, to upgrade to OS X Mountain Lion, the following must be done:

Step 1: Make sure your Mac can run Lion.

To run OS X Mountain Lion, your Mac must have a 64-bit capable Intel Core 2 Duo processor or better processor, as well as

being capable of booting the Mountain Lion 64-bit kernel, 64-bit EFI, and 64-bit graphics drivers.

Find out if your current Mac has one of these processors by clicking the Apple icon at the top left of your screen, then choosing About This Mac.

General Requirements

* OS X v10.6.8 or later

* 2GB of memory

* 8GB of available space

* Some features require an Apple ID; terms apply.

* Some features require a compatible Internet service provider; fees may apply.

Supported Models

* iMac (Mid 2007 or newer)

* MacBook (Late 2008 Aluminum, or Early 2009 or newer)

* MacBook Pro (Mid/Late 2007 or newer)

* Xserve (Early 2009)

* MacBook Air (Late 2008 or newer)

* Mac mini (Early 2009 or newer)

* Mac Pro (Early 2008 or newer)

For further information read this article and for a list of non-compatible real Macs, read this article.

Step 2: Make sure you have the latest version of OS X Snow Leopard or OS X Lion.

Get up to date with the latest version of OS X Snow Leopard or OS X Lion to purchase OS X Mountain Lion from the Mac App Store.

If you have Snow Leopard, click the Apple icon and choose Software Update to install the latest version, which is 10.6.8.

If you have Lion, click the Apple icon and choose Software Update to install the latest version, which is 10.7.4.

Step 3: Download OS X Lion from the Mac App Store.

Open the Mac App Store from your Dock to buy and download Lion. Then follow the onscreen instructions to install it.

In the case of OSx86 / Hackintosh PCs, the equivalent steps are:

Step 1: Make sure your OSx86 / Hackintosh PC can run Mountain Lion.

Initial Requirements:

* A 64-bit capable Intel Core 2 Duo processor or better processor, as well as being capable of booting the Mountain Lion 64-bit kernel, 64-bit EFI, and 64-bit graphics drivers.

* OS X v10.6.8 or later

* 2GB of memory

* 8GB of available space

* Some features require an Apple ID; terms apply.

* Some features require a compatible Internet service provider; fees may apply.

Further Requirements:

1. If your PC has a CPU that System Profiler lists as 'Unknown' even though it is an Intel CPU, it is not just a case of editing:

The AppleSystemInfo.strings "UnknownCPUKind" entry from "Unknown" to, for example, "Intel® Core™2 Quad CPU Q6600" (found in OS X 10.6.8 /System/Library/CoreServices/Resources/English.lproj/}.

[ii] The AboutThisMac.strings for Processor text fields in the About This Mac window (found in 10.6.8 /System/Library/CoreServices/loginwindow.app/Contents/Resources/), to get, for example, "3.0 MHz Intel® Core™2 Quad CPU Q6600" to display properly in the About This Mac window.

because these changes are purely cosmetic......OS X still regards your CPU as Unknown......consequently, some software installers (if not hacked) will fail to install because the CPU is not properly detected, e.g. the Microsoft Silverlight installer.

The solution is to use a bootloader with auto-CPU detection (following the work of DigitalDJ; see here).

RECOMMENDATION: Try using a current Chameleon bootloader version, such as Chameleon Chameleon v2.1svn r2042

Hence, with a Core2Quad CPU, e.g. Q6600, the Chameleon v2.1svn r2042 bootloader will inject a "Quad-Core Intel Xeon" CPU-type......

2. It is necessary to use a SMBIOS.plist which gives 'vaild' details as far as OS X Snow Leopard, OS X Lion and OS X Mountain Lion are concerned for the following keys:

<key>SMbiosdate</key>
<key>SMbiosversion</key>
<key>SMboardproduct</key>
<key>SMfamily</key>
<key>SMmanufacter</key>
<key>SMproductname</key>
<key>SMserial</key>

because in OS X Lion 10.8 /System/Library/CoreServices/PlatformSupport.plist, there is a list of Supported Board IDs:

Recommendation: Use the very useful Extra Folder Installer prepared by MaLd0n:

Extra_Lion.pkg.zip

and run the Installer with the Extra Folder option UNCHECKED but CHECK the smbios.plist option that is applicable to your CPU:

iMac9,1 -> Intel Core 2 Duo ("Penryn")
iMac10,1 -> Intel Core 2 Duo ("Wolfdale")
iMac11,1 -> Core i5, or Core i7 ("Nehalem")
iMac11,2 -> Intel Core i3 or Core i5 ("Clarkdale")
iMac11,3 -> Intel Core i3, Core i5, or Core i7 ("Clarkdale, Lynnfield")
iMac12,1 -> Intel Core i5 or Core i7 ("Sandy Bridge")
iMac12,2 -> Intel Core i5 or Core i7 ("Sandy Bridge")
MacBook2,1 -> Intel Core 2 Duo Mobile ("Merom") / Intel Graphics Media Accelerator (GMA) 950
MacBook4,1 -> Intel Core 2 Duo Mobile ("Penryn") / Intel Graphics Media Accelerator (GMA) X3100
MacBookPro4,1 -> Intel Core 2 Duo Mobile ("Penryn") / NVIDIA GeForce
MacBookPro6,1 -> Intel Core i5 or Core i7 Mobile ("Arrandale") / NVIDIA GeForce and Intel HD Graphics
MacBookPro8,1 -> Intel Core i5 or Core i7 Mobile ("Sandy Bridge") / Intel HD Graphics 3000
MacBookPro8,3 -> Intel Core i7 Mobile ("Sandy Bridge") / AMD Radeon HD and Intel HD 3000 Graphics
MacPro3,1 -> Intel Xeon 5400 series ("Harpertown") / Use for Core2Quad
MacPro4,1 -> Intel Xeon 3500 or 5500 series ("Bloomfield, Gainestown") / Use for Core i Nehalem/ Quad Core HT / Line 9xx
MacPro5,1 -> Intel Xeon W3530, W3565, W3680, E5620, X5650, or X5670 ("Bloomfield, Westmere") / Use for Core i Nehalem/ Quad or Six Core HT / Line 9xx

I have found that without the correct SMBIOS.plist details, i.e. all the details recognisable as 'valid' by the Apple App Store, it is not possible to purchase and download the Install Mac OS X Lion app from the App Store, even though other software can be purchased and downloaded via the App Store using a 'validated' Apple ID......

For example, I have found that using SMBIOS.plist details for a MacPro2,1 with my Core2Quad Q6600 CPU, which results in my OSx86 / Hacintosh PC being recognised by Geekbench as a Mac:

did not enable the purchase and download of the Install Mac OS X Lion app, whereas using 'valid' SMBIOS.plist details for a MacPro3,1 (thanks to MaLd0n), which results in my OSx86 / Hackintosh PC being recognised by Geekbench as a Hackintosh:

did enable the purchase and download of the Install Mac OS X Lion app.....!

So, a OSx86 / Hackintosh PC being recognised by Geekbench as a Hackintosh is not necessarily an obstacle to being able to purchase and download the Install Mac OS X Lion app from the Apple App Store........

Step 2: Make sure you have the latest version of Snow Leopard or Lion.

While Apple have recommended using the latest version OS X Snow Leopard version, which is 10.6.8 (make sure you run Software Update, so that the recently released Mac OS X 10.6.8 Supplemental Update is installed; alternatively, you can download and run the standalone Mac OS X 10.6.8 Update Combo v1.1.....the same advice to use the standalone Update Combo applies if you are running OS X Lion, i.e. MacOSXUpdCombo10.7.4.dmg.

However, some IM members have had problems with 10.6.8 but success with 10.6.7 when attempting to purchase and download the Install Mac OS X Lion app.....so, if 10.6.8 does not work for you, try 10.6.7, or even 10.6.6.....the same advice applies if you are running OS X Lion.

Step 3: Download OS X Mountain Lion from the Mac App Store.

Before attempting to purchase and download the Install Mac OS X Lion app from the Apple App Store, you should check the following:

That you can enter your Apple ID and password and have it accepted.......

If you have problem, then follow the procedure recommended by Apple.....the procedure has worked for me on an Ethernet connection.....

[ii] That you can start the process of purchasing software from the App Store......

[iii] Read Section 1 of Part B. of this guide (in post #1)

If and [ii] are achievable and [iii] has been done, then you should hopefully be able to open the Mac App Store from your Dock to buy and download Install OS X Mountain.app BUT DO NOT click on the “Install OS X Mountain Lion” installer app icon that will show up in the Dock......If you still have problems then try the following:

[1] Go to System Preferences, then to Network......select your Network Service i.e. Ethernet or AirPort in the sidebar and click the '-' tab at the sidebar bottom, which will delete the service

[2] Modify your org.chameleon.Boot.plist by adding in the following:

<key>EthernetBuiltIn</key>
<string>Yes</string>

If you have a PIC NIC installed it may also be necessary to add an entry in org.chameleon.Boot.plist for PCIRootUID because a MOBO may have pciroot=0 or pciroot=1, shown here for pciroot=1:

<key>PCIRootUID</key>
<string>1</string>

To find your pciroot value, use this command in Terminal:

ioreg -l | grep -15  "AppleACPIPCI" | grep "_UID"

which should give "_UID" = "1" or "_UID" = "0".

[3] Reboot into OS X Lion and again go to System Preferences > Network......but now click the '+' tab at the sidebar bottom, to add a new Network Service named Ethernet (en0) for your LAN service.....

I have a PIC NIC that is connected to the internet under the Network Service name 'Ethernet Adaptor (en0)' but is seen as built-in......System Profiler says against Ethernet Cards: This computer does not appear to have any PCI Ethernet cards installed.

I wish you the same success I had in purchasing and downloading the Install Mac OS X Lion app from the Apple App Store...... Posted Image

If you have problems with using

<key>EthernetBuiltIn</key>
<string>Yes</string>

and/or

<key>PCIRootUID</key>
<string>1</string>

then go to post #4 Issue 2 Setting up Builtin Ethernet / LAN0 / (en0)

*************************************************************

Part B. Making a Bootable GPT Partitioned USB Flash Drive OS X Lion 10.8 Installer

*************************************************************

1. You will need:

[1] Access to a working Mac or Hack x86 OS X Snow Leopard 10.6.8 or OS X Lion 10.7.4

(I am assuming that you already have OS X Snow Leopard 10.6.8 or OS X Lion 10.7.4 installed and running)

[2] A 8GB USB flash drive (memory stick)

[3] To be able to purchase and download OS X Mountain Lion from the Apple App Store. See Part A.

[4] To download my "verdant_Mountain Lion_Support_Files_v1.0.zip" folder

The “Install OS X Mountain.app” installer app icon will show up in the Dock.

If it does, then the installer should also show up in your Applications folder.

* DO NOT click on the icon NOR right-click on the icon and select Open

* DO NOT double-click on its icon in the Applications folder

2. Extracting Necessary Files from Lion Installer App

[1] Boot into Snow Leopard or OS X Lion and go to the Applications folder and find Install OS X Mountain.app WITHOUT clicking on the icon NOR right-click on the icon and selecting Open

[2] Unhide all files via a Terminal command:

***********************************************************

Terminal commands to show/hide hidden and system files:

To show hidden and system files:

defaults write com.apple.finder AppleShowAllFiles TRUE

killall Finder

To hide hidden and system files:

defaults write com.apple.finder AppleShowAllFiles FALSE

killall Finder

***********************************************************

Or, you can download and run TinkerTool......select the Finder options: 'Show hidden and system files' option and then click Relaunch Finder to unhide......and deselect the Finder options: 'Show hidden and system files' option and then click Relaunch Finder to hide......

[3] Right-click on the Install OS X Mountain.app installer icon and select Show Package Contents.

Open the Contents folder and the SharedSupport folder within it, and look for InstallESD.dmg

[4] Open i.e. mount InstallESD.dmg and look for BaseSystem.dmg……LEAVE the Mac OS X Install ESD window open…….

3. Preparing the USB flash drive as a Mac bootable device volume

[1] Plug in the USB flash drive and then using the Snow Leopard or Lion Disk Utility, partition/format it as a single GPT/HFS+ volume named OSX_Lion_USB_Installer (or your chosen name without spaces) as follows:

In the Disk Utility sidebar, highlight your USB flash drive device icon

In the Disk Utility main window, click on the Partition tab and select to partition as 1 volume, using a name with no spaces and format as Mac OS Extended (Journaled)……

Then click on Options button -> select GUID Partition Table (GPT) -> click Apply

Doing this will make the USB flash drive bootable on a Mac. Note that this operation will erase everything on the drive.

4. Installing necessary /Extra/ and /Extra/Extensions/ directory files and the Chameleon v2.1svn r2042 bootloader onto the partitioned/formatted USB flash drive

[1] In the Disk Utility main window, click on the Restore tab to load the BaseSystem.dmg onto the OSX_Lion_USB_Installer volume.....doing this puts a base OS X Lion system on the USB flash drive volume……

Choose the BaseSystem.dmg file as the Source by 'drag and dropping' it from the Mac OS X Install ESD window into the Source Window (note that a '+ in green circle' appears momentarily)

Choose your USB flash drive volume icon as the Destination by 'drag and dropping' it from the Disk Utility sidebar into the Destination window (note that a '+ in green circle' appears momentarily).

Click the Apply button and it will create your bootable USB drive. Note that Erase destination checkbox will be ticked by default.

The USB flash drive device name will be automatically changed to Mac OS X Base System in the sidebar……

[2] On the USB flash drive volume, open the System folder and double-click on the Installation folder within it…..this opens an Installation folder window….

Right-click on the Packages alias icon and select Move to Trash

Go to the open Mac OS X Install ESD window and 'drag and drop' the Packages folder in the window into the open Installation folder window……the 3.85 GB Packages folder will take about 10 or minutes to copy over……

Also 'drag and drop' the mach_kernel file from the open Mac OS X Install ESD window into the into the USB flash drive volume's / directory…….i.e. into the open Mac OS X Base System Window……

[3] Note that the USB flash drive Mac OS X Base System volume /System/Library/Extensions/ folder does not contain all the graphics kexts that the installed OS X Mountain Lion /System/Library/Extensions/ does. The Mac OS X Base System volume /System/Library/Extensions/ folder is missing the following kexts, bundles and plugins, as well as the BJUSBLoad.kext:

AMDRadeonAccelerator.kext
AMDRadeonVADriver.bundle
AMDRadeonX3000GLDriver.bundle
AppleIntelHD3000Graphics.kext
AppleIntelHD3000GraphicsGA.plugin
AppleIntelHD3000GraphicsGLDriver.bundle
AppleIntelHD3000GraphicsVADriver.bundle
AppleIntelHD4000Graphics.kext
AppleIntelHD4000GraphicsGA.plugin
AppleIntelHD4000GraphicsGLDriver.bundle
AppleIntelHD4000GraphicsVADriver.bundle
AppleIntelHDGraphicsGLDriver.bundle
AppleIntelIVBVA.bundle
ATIRadeonX2000GA.plugin
ATIRadeonX2000GLDriver.bundle
ATIRadeonX2000VADriver.bundle
GeForce.kext
GeForceGA.plugin
GeForceGLDriver.bundle
GeForceVADriver.bundle

Thus, depending on your installed graphics card i.e. nVidia or ATI, you may need to use Pacifist v3.0.8 to extract the relevant kexts, bundles and plugin from /Volumes/Mac\ OS\ X\ Install\ ESD/Packages/Essentials.pkg into the USB flash drive Mac OS X Base System volume /System/Library/Extensions/ folder, in order for your GPU and display to function properly when booting from the Bootable GPT Partitioned USB Flash Drive OS X Lion 10.8 Installer, i.e. not present you with a black display screen at worst, or less worse, an incorrect and fixed display resolution, on reaching the OS X Lion Installer window.

Since I have an Inno3D GeForce 9800GT 512MB graphics card, I had to extract the following files into my USB flash drive Mac OS X Base System volume /System/Library/Extensions/ folder so that booting the USB installer did not just present me with a black display screen on reaching the OS X Lion Installer window:

GeForce.kext

GeForceGA.plugin

GeForceGLDriver.bundle

GeForceVADriver.bundle

Please be note that being able to use GraphicsEnabler=Yes in org.chameleon.Boot.plist for the same graphics card under different OS X versions via different Chameleon bootloader versions/revisions is not a given.

For example, with my Inno3D GeForce 9800GT 512MB graphics card, to get full CI/QE and changeable display resolutions, the situation is as follows:

OS X Leopard 10.5.8 - GraphicsEnabler=No and NVEnabler.kext

OS X Snow Leopard 10.6.8 - GraphicsEnabler=Yes and so no NVinjector kext such as NVEnabler64.kext

OS X Lion 10.7.4 - GraphicsEnabler=No and NVEnabler64.kext

OS X Mountain Lion 10.8.0 - GraphicsEnabler=No and either a <key>device-properties</key> custom hex entry in org.chameleon.Boot.plist, that I generated using OSX86 Tools, or NVEnabler 64.kext

For help with:

1. ATI graphics cards go here

2. nVidia graphics cards go to post #3 in this topic for single nVidia graphics card use

3. Multiple nVidia graphics card(s) and/or displays go here.

4. For help with mixed multiple ATI and/or nVidia graphics cards and /or multiple displays, Google is your friend......as are aqua-mac, netkas, and others.......

[4] Run the Chameleon-2.1svn-r2042.pkg installer (in the verdant_Mountain Lion_Support_Files_v1.0 folder) and click on the Continue button in the Chameleon v2.1svn r2042 Bootloader Installer window…….then click Continue and Continue again and Agree…..then in the Standard Install window click Change Install Location and select the USB flash drive Mac OS X Base System volume in the Select a Destination window and click Continue……then click Install…..after a hopefully successful install, click Close....

[5] Go back to the open Mac OS X Base System Window……the Chameleon bootloader installer should have created the /Extra/ and /Extra/Extensions/ directories or folders……BUT you may have to create them manually afterward (as I did)……

[6] Copy across from your running 64bit mode Snow Leopard or Lion system, your MOBO's OS X DSDT.aml file into the open target HDD OS X Lion System Window, i.e. the target HDD volume's / directory…….

[7] Copy across from your running 64bit mode Snow Leopard or Lion system, or from the verdant_Mountain Lion_Support_Files_v1.0 folder, into /Extra/ on the USB flash drive Mac OS X Base System volume, the following .plist files:

smbios.plist for MacPro3,1 (use the one from MaLd0n's Lion installation via USB stick using Chameleon, DP4, GM and FINAL topic…….), or whatever MacProx,y designation matches your CPU....

org.chameleon.Boot.plist (assuming that you are using a recent/current Chameleon boot loader version later than v2.0 r11xx, or a version 2.1 revision)

Also copy across (if you wish) your Chameleon bootloader Themes folder from your running 64bit mode Snow Leopard or Lion system, or from the folder....

[8] Copy the following kexts in /Extra/Extensions/ on your running 64bit mode Snow Leopard or Lion system, or from the verdant_Mountain Lion_Support_Files_v1.0 folder, into /Extra/Extensions/ on the USB flash drive Mac OS X Base System volume...

FakeSMC.kext

EvOreboot.kext

NullCPUPowerManagement.kext

AppleRTC.MLion.Patched.kext

AppleNForceATA.imk64bit.kext

AD1998b.FIX.kext or VoodooHDA.kext (for AD1998b) if this is the audio chipset/codec of your nForce chipset + Intel CPU MOBO

You may also have AppleHDA.10.6.2.kext, FakeSMC.kext and nForceLAN.0.64.5.kext in /Extra/Extensions/.

Note the later versions/revisions of FakeSMC.kext v3.0 and later by mojodojo can function from /Extra/Extensions/ or from /System/Library/Extensions/ but be aware that earlier versions/revisions of FakeSMC.kext can only function from /System/Library/Extensions/ - hence step [8] below:

[9] If you have AppleHDA.10.6.2.kext, FakeSMC.kext and nForceLAN.0.64.5.kext in /System/Library/Extensions/ on your running 64bit mode Snow Leopard or Lion system, then these need to copied from there, or from the verdant_Mountain Lion_Support_Files_v1.0 folder, into /System/Library/Extensions/ on the USB flash drive Mac OS X Base System volume……

[10] Having added AppleHDA.10.6.2.kext, FakeSMC.kext and nForceLAN.0.64.5.kext to /System/Library/Extensions/ on the USB flash drive Mac OS X Base System volume, you need to use Terminal to reset the kexts ownership and permissions and rebuild the kernelcache file etc.....alternatively, you can use janek202's Kext Wizard for a Terminal-free life.......

In Terminal type:

sudo chown -R root:wheel /Volumes/Mac\ OS\ X\ Base\ System/System/Library/Extensions
sudo chmod -R 755 /Volumes/Mac\ OS\ X\ Base\ System/System/Library/Extensions
sudo touch /Volumes/Mac\ OS\ X\ Base\ System/System/Library/Extensions

followed by

sudo chflags nouchg /Volumes/Mac\ OS\ X\ Base\ System/System/Library/CoreServices/boot.efi
exit

[11] Close all open folders within the Mac OS X Base System folder and in the Terminal type:

sudo chown -R 0:0 /Volumes/Mac\ OS\ X\ Base\ System

[12] Close Terminal and then go to /System/Library/Caches/com.apple.kext.caches/Startup and delete the files within Startup….

Part C. Installing a Bootable OS X Mountain Lion (OS X 10.8) system on a GPT Partitioned Hard Drive Volume Using a Bootable GPT USB Flash Drive Installer

*************************************************************

1. Preparing the target Hard Drive volume as a Mac bootable device volume

[1] Use the running Snow Leopard or Lion Disk Utility to partition/format your target HDD volume for OS X 10.8 as GPT/HFS+ volume named OSX_10.8_GPT_A (or your chosen name without spaces)

****************************************************

VERY IMPORTANT TO CHECK : OS X target HDD ownership

****************************************************

Right-click on the target OS X HDD volume icon on your Desktop, and select Get Info. If the checkbox next to "Ignore ownership on this volume" is checked then click on the padlock symbol to authenticate and UNCHECK the checkbox.

Then to ensure that the target OS X HDD volume's root directory is owned by the root user, go to Terminal and type: (note that using 0:0 is equivalent to using root:wheel)

sudo chown 0:0 /Volumes/"your target OS X HDD volume name"

This is to make certain that the permissions are not scrambled after the installation of OS X.....and hence that you are able to boot from the OS X 10.8 hard drive........

[2] Now close all open windows on the Snow Leopard or Lion Desktop and any open applications.......

Reboot your PC and press the F8 key (or whichever key you need to) IMMEDIATELY after the message "Press DEL to enter SETUP, Press TAB to display BIOS POST message" or similar appears on-screen, in order to bring up the message "Loading Boot Menu......"

When the PC BIOS "Boot Menu" window appears on-screen, select the USB flash drive OS X Mountain Lion installer from the list of bootable drives presented in the "Boot Menu", and press Enter......

OR

Choose it from the list of bootable volumes presented by the Chameleon bootloader.....

Boot from the USB flash drive Mac OS X Base System volume and follow the onscreen Mac OS X Installer instructions to install OS X Lion onto the target HDD volume.....

[3] Re-boot back into OS X Snow Leopard or OS X Lion and run the Chameleon-2.1svn-r2042.pkg installer (in the verdant_Mountain Lion_Support_Files_v1.0 folder) and click on the Continue button in the Chameleon v2.1svn r2042 Bootloader Installer window…….then click Continue and Continue again and Agree…..then in the Standard Install window click Change Install Location and select the target HDD OS X Mountain Lion volume icon in the Select a Destination window and click Continue……then click Install…..after a hopefully successful install, click Close…..

[4] Set up your video driver as you have done for running OS X 10.6.8 Snow Leopard in 64bit mode or OS X Lion 10.7.4 in default 64bit mode......

[5] Go back to the open target HDD OS X Mountain Lion System Window……the Chameleon bootloader installer should have created the /Extra/ and /Extra/Extensions/ directories or folders……BUT you may have to create them manually afterward (as I did)……

[6] Copy across from your running 64bit mode Snow Leopard system, or running OS X Lion 10.7.4 system, the DSDT.aml file into the open target HDD OS X Mountain Lion System Window, i.e. the target HDD volume's / directory…….

[7] Copy across from your running 64bit mode Snow Leopard system, or running OS X Lion 10.7.4 system, into /Extra on the target HDD volume, the following .plist files:

smbios.plist for MacPro3,1 (use the one from MaLd0n's Lion installation via USB stick using Chameleon, DP4, GM and FINAL topic…….), or whatever MacProx,y designation matches your CPU....

org.chameleon.Boot.plist (assuming that you are using a recent/current Chameleon boot loader version later than v2.0 r11xx, or a version 2.1 revision)

Also copy across (if you wish) your Chameleon bootloader Themes folder from your running 64bit mode Snow Leopard or Lion system, or from the folder....

[8] Copy the following kexts in /Extra/Extensions/ on your running 64bit mode Snow Leopard, or in /System/Library/Extensions/ on your running Lion system, or from the verdant_Mountain Lion_Support_Files_v1.0 folder, into /System/Library/Extensions/ in the open target HDD OS X Lion System Window……

FakeSMC.kext

EvOreboot.kext

NullCPUPowerManagement.kext

(NullCPUPowerManagement.kext is not present or needed if you have already enabled, or are going to enable, Natural Power Management i.e. "vanilla SpeedStepping")

AppleNForceATA.imk64bit.kext

AD1998b.FIX.kext or VoodooHDA.kext

(AD1998b.FIX.kext or VoodooHDA.kext are only present or needed if AD1988b the audio chipset/codec of your nForce chipset + Intel CPU MOBO; alternatively, you may have or need AppleHDA.10.6.2.kext for audio in /System/Library/Extensions/)

Then also copy the AppleRTC.MLion.Patched.kext from the verdant_Mountain Lion_Support_Files_v1.0 folder, into /System/Library/Extensions/ in the open target HDD OS X Mountain Lion System Window…

Alternatively, you can directly patch the installed OS X Mountain Lion AppleRTC.kext in /System/Library/Extensions/ in the open target HDD OS X Mountain Lion System Window, by running this perl script in Terminal, which has been posted by rayap, which forces an unconditional jump over the rtcWrites() in updateChecksum() to prevent CMOS Resets:

sudo perl -pi -e 's|\x75\x30\x89\xd8|\xeb\x30\x89\xd8|' /System/Library/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC

N.B. If you have added the AppleRTC.MLion.Patched.kext from the verdant_Mountain Lion_Support_Files_v1.0 folder, into /System/Library/Extensions/ in the open target HDD OS X Mountain Lion System Window, then to ensure that this is the RTC kext that is loaded, rename the installed OS X Mountain Lion AppleRTC.kext in /System/Library/Extensions/ in the open target HDD OS X Mountain Lion System Window using the Terminal as follows:

sudo mv /Volumes/"your target OS X Mountain Lion HDD volume name"/System/Library/Extensions/AppleRTC.kext /Volumes/"your target OS X Mountain Lion HDD volume name"/System/Library/Extensions/AppleRTC.kext_Original

Note the later versions/revisions of FakeSMC.kext v3.0 and later by mojodojo can function from /Extra/Extensions/ or from /System/Library/Extensions/ but be aware that earlier versions/revisions of FakeSMC.kext can only function from /System/Library/Extensions/ - hence step [9] below:

[9] If you have AppleHDA.10.6.2.kext, FakeSMC.kext and nForceLAN.0.64.5.kext in /System/Library/Extensions/ on your running 64bit mode Snow Leopard system, or in /System/Library/Extensions/ on your running Lion system, then these kexts need to copied from there, or from the verdant_Mountain Lion_Support_Files_v1.0 folder, into /System/Library/Extensions/ in the open target HDD OS X Mountain Lion System Window……

[10] Having added these non-vanilla, i.e. non- Apple kexts, plus any others specific to your system; for example, I have added:

ACPIMonitor.kext

AppleNForceATA.imk64bit.kext

AppleRTL8169Ethernet.kext

AppleRTC.kext_ORIG

AppleRTC.MLion.Patched.kext

EvOreboot.kext

FakeSMC.kext

IntelCPUMonitor.kext

IntelThermal.kext

nForceLAN.0.64.5.kext

NVClockX.kext

SuperIOFamily.kext

VoodooHDA.kext

to /System/Library/Extensions/ on the open target HDD OS X Mountain Lion System Window, you need to use Terminal to reset the kexts ownership and permissions and rebuild the kernelcache file……alternatively, you can use janek202's Kext Wizard for a Terminal-free life.......

In Terminal type:

sudo chown -R root:wheel /System/Library/Extensions
sudo chmod -R 755 /System/Library/Extensions
sudo touch /System/Library/Extensions
exit

Close Terminal and then go to /System/Library/Caches/com.apple.kext.caches/Startup and delete the files within Startup….

KextPropertyValues_OSBundleHelper_x86_64.plist.gz

[11] Close the open target HDD OS X Mountain Lion System Window and boot from the target hard drive OS X Lion System volume......

[12] If you find that on shutting down OS X Lion and rebooting, that the CMOS has been "wiped clean" of your custom BIOS settings profile and the BIOS has reverted to using the in-built default BIOS settings, then reload your backed-up custom BIOS settings profile from its source (e.g. USB flash drive) and boot back into OS X Lion......

If this happens, then you have either not copied the AppleRTC.MLion.Patched.kext from the verdant_Mountain Lion_Support_Files_v1.0 folder, into /System/Library/Extensions/ in the open target HDD OS X Mountain Lion System Window, or not directly patched the installed OS X Mountain Lion AppleRTC.kext in /System/Library/Extensions/ in the open target HDD OS X Mountain Lion System Window, by running this perl script in Terminal, which has been posted by rayap, which forces an unconditional jump over the rtcWrites() in updateChecksum() to prevent CMOS Resets:

sudo perl -pi -e 's|\x75\x30\x89\xd8|\xeb\x30\x89\xd8|' /System/Library/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC

N.B. If you have added the AppleRTC.MLion.Patched.kext from the verdant_Mountain Lion_Support_Files_v1.0 folder, into /System/Library/Extensions/ in the open target HDD OS X Mountain Lion System Window, then to ensure that this is the RTC kext that is loaded, rename the installed OS X Mountain Lion AppleRTC.kext in /System/Library/Extensions/ in the open target HDD OS X Mountain Lion System Window using the Terminal as follows:

sudo mv /Volumes/"your target OS X Mountain Lion HDD volume"/System/Library/Extensions/AppleRTC.kext /Volumes/"your target OS X Mountain Lion HDD volume name"/System/Library/Extensions/AppleRTC.kext_Original

Now you need to again use Terminal to reset the kexts' ownership and permissions and rebuild the kernelcache file etc.....alternatively, you can use janek202's Kext Wizard for a Terminal-free life.......

In Terminal type:

sudo chown -R root:wheel /System/Library/Extensions
sudo chmod -R 755 /System/Library/Extensions
sudo touch /System/Library/Extensions
exit

Close Terminal and then go to /System/Library/Caches/com.apple.kext.caches/Startup and delete the files within Startup….

[13] Close the open target HDD OS X Mountain Lion System Window and re-boot from the target hard drive OS X Mountain Lion System volume......

[14] Use the OS X Mountain Lion Disk Utility to repair the HDD OS X Mountain Lion system permissions......

N.B. If you experience the [PCI configuration begin] error on booting from the OS X Mountain Lion System installed on your target HDD volume, then see post #6, which gives four proposed solutions to this error.......

*************************************************************

Part D. Installing a Bootable OS X Mountain Lion (OS X 10.8) system on a MBR or GPT Partitioned Hard Drive Volume Using a Bootable GPT USB Flash Drive Installer

*************************************************************

There are two possible procedures you can follow, depending on your situation:

Procedure 1. (No pre-existing OS X Mountain Lion (OS X 10.8) system installation)

This 2-stage procedure assumes that you have already followed "Part B. Making a Bootable GPT Partitioned USB Flash Drive OS X Lion 10.8 Installer" of this guide, and now have a working bootable GPT USB Flash Drive Installer......

In order for you to install OS X Mountain Lion 10.8 onto your target HDD volume partitioned/formatted as MBR/HFS+ you need to use a modified OSInstall.mpkg package and OSInstall Unix executable file in place of the ones that the OS X Mountain Lion Installer on your bootable GPT USB Flash Drive Installer uses......

The versions of OSInstall.mpkg and OSInstall that I have used have been posted by crazybirdy and are based on nawcom's work. The Board-ID and RAM checks have been removed, and some Custom Install Options have been added too.

Here is a zipped archive for your convenience: 2815-OSInstall(MBR)+OSInstall.zip

Stage 1. Inserting the MBR modified OSInstall.mpkg package and OSInstall Unix executable file in place of the ones that the downloaded OS X Mountain Lion Installer on your bootable GPT USB Flash Drive Installer uses

Download and unarchive the 2815-OSInstall(MBR)+OSInstall.zip file…….the unarchived folder contains the modified OSInstall.mpkg package and the OSInstall Unix executable file.

The procedure for installing the modified OSInstall.mpkg package and OSInstall Unix executable file on your bootable GPT USB Flash Drive Installer in place of the original OS X Mountain Lion Installer versions is as follows:

1. Unhide the hidden and systems files on your OS X Mountain Lion USB Flash Drive Installer, named Mac OS X Base System, using Terminal commands or Tinker Tool (see Part C. above)

2. Go to Terminal and then:

[1] Either type:

cd /Volumes/Mac\ OS\ X\ Base\ System/System/Installation/Packages

or type

cd

and press the 'Space Bar', and then having navigated to System, then to Installation, then to Packages, 'drag and drop' the Packages folder into Terminal……

[2] Type the following:

sudo mv OSInstall.mpkg OSInstall.mpkg.GPT
ls

Note that you have now renamed the original file as shown by the 'ls' command…..

[3] Either type:

cd /Volumes/Mac\ OS\ X\ Base\ System/System/Library/PrivateFrameworks/Install.framework/Frameworks/OSInstall.framework/Versions/A

or type

cd

and press the 'Space Bar', and then having navigated to System, then to Library, then to PrivateFrameworks, then to Install.framework, then to Frameworks, then to OSInstall.framework, then to Versions, and finally to the A folder, 'drag and drop' the A folder into Terminal……

[4] Type the following:

sudo mv OSInstall OSInstall.GPT
ls
exit

Note that you have now renamed the original file as shown by the 'ls' command…..

****************************************************

As a reminder if ever you wish to revert back to the original GPT installer versions......simply rename the original files by removing the .GPT extensions after having renamed the patched files with the .MBR extension, via Terminal:

cd /Volumes/Mac\ OS\ X\ Base\ System/System/Installation/Packages																															
sudo mv OSInstall.mpkg OSInstall.mpkg.MBR
sudo mv OSInstall.mpkg.GPT OSInstall.mpkg

followed by

cd /Volumes/Mac\ OS\ X\ Base\ System/System/Library/PrivateFrameworks/Install.framework/Frameworks/OSInstall.framework/Versions/A
sudo mv OSInstall OSInstall.MBR																										
sudo mv OSInstall.GPT OSInstall																						
exit

****************************************************

3. Then either 'drag and drop' the chosen version of OSInstall.mpkg into /Volumes/Mac\ OS\ X\ Base\ System/System/Installation/Packages......(or use cp command via Terminal):

sudo cp -p -R /Users/"User Name"/Desktop/2815-OSInstall\(MBR\)+OSInstall/OSInstall.mpkg /Volumes/Mac\ OS\ X\ Base\ System/System/Installation/Packages

4. Then 'drag and drop' OSInstall into /Volumes/Mac\ OS\ X\ Base\ System/System/Library/PrivateFrameworks/Install.framework/Frameworks/OSInstall.framework/Versions/A......(or use cp command via Terminal):

sudo cp -p -R /Users/"User Name"/Desktop/2815-OSInstall\(MBR\)+OSInstall/OSInstall /Volumes/Mac\ OS\ X\ Base\ System/System/Library/PrivateFrameworks/Install.framework/Frameworks/OSInstall.framework/Versions/A

5. Close all windows.......

6. Now follow the following procedure in Stage 2. to install OS X Mountain Lion 10.8 onto your target HDD volume partitioned/formatted as MBR/HFS+ :

Stage 2. Preparing the target Hard Drive volume as a Mac bootable device volume

[1] Use the running Snow Leopard or Lion Disk Utility to partition/format your target HDD volume for OS X 10.8 as GPT/HFS+ volume named OSX_10.8_GPT_A (or your chosen name without spaces)

****************************************************

VERY IMPORTANT TO CHECK : OS X target HDD ownership

****************************************************

Right-click on the target OS X HDD volume icon on your Desktop, and select Get Info. If the checkbox next to "Ignore ownership on this volume" is checked then click on the padlock symbol to authenticate and UNCHECK the checkbox.

Then to ensure that the target OS X HDD volume's root directory is owned by the root user, go to Terminal and type:

sudo chown 0:0 /Volumes/"your target OS X HDD volume name"

(Note: root:wheel and 0:0 are equivalent; but it is good to know both)
