Instructions to update  are pretty clear in this post. However, avoid a reboot is not so simple as it seems. Every tutorial to update to 10.6.4 starts saying “Install 10.6.4 update, an before reboot…”. My problem is that I did it through the software updates, and it installed the actual update WHILE rebooting, so once installed and automatically rebooted, you’re sold. Probably with the combo update you are more lucky.

So basically, what you should do is:

• Install 10.6.4 update.
• Without reboot you’ll need to change some boot files on your efi partition as well as patch DSDT if you didn’t in previous updates. You can forget about the sleepenabler kext there found as you will be using the native power management kexts (see the links above).

Now you installed the update, and your computer rebooted, and Snow Leopard won’t start. How do you complete the process??

You need your USB Key/USB Hard drive you used to make the vanilla install. Remember?

• Connect your drive to you netbook, and reboot. Select the USB device as boot device in you BIOS/Start menu. Chameleon will start. If you select your main hard drive to boot from chameleon, it will not work. ou have to boot from the Install DVD image partitio that you made.
• Once the installation starts, go to the upper menu and open a Terminal from Utilities menu.
• The main hard drive (the partition where you installed Snow Leopard) should be already mounted by now at /Volumes/hackintosh (or whatever you named your partition).

To change the EFI partition boot file, you can manually mount the EFI partition in /Volumes and just copy it over, assuming you have the boot file somewhere. However, if you need to mess around with the kexts, patch the DSDT and rebuild the cache like I had to,  the safest way is to chroot the the new disk and do it using the typical update scripts.

chroot /Volumes/hackintosh

• From here, the process is as always. Go to your Vanilla folder. To patch DSDT copy the DSDT.aml file and run the update.sh script. -Run the 27ae.sh script to patch video kexts.
• To change the kexts, remove sleepenabler, add the new ones and run update.sh to copy them and rebuild the kext cache. (follow the instructions to modify the SMSBIOS in the linked post).

Now reboot, and you should be ready to go.

If you have been looking for imformation about virtualizing LEopard or Snow Leopard, you’ll probably stumble upon this two sites, which contain most of the useful information. However, when it comes to Snow Leopard, information is spread across hundreds of posts, and most of it is for MS Windows only.

There’s another attempt using empire-efi here, which didn’t worked for me.

I just wrote a guide myself about how to get Snow Leopard working under Ubuntu 9.10 and Virtualbox 3.1.6r59338 and I was about to post it. However, I found another guide, for windows, which will work flawlessly under Linux with some minor tweaks, and has step-by-step screenshots, so I guess there’s no need to duplicate the content there.

Here’s exactly what I did to get things working:

First you need, a Leopard OsX86 working virtualbox machine. To get Leopard working, download any OsX86 distro and install it following this guide. I used iDeneb 1.6 and worked fine.

You DO NOT need to patch the VirtualBox files in order to get Leopard working, so just create the VM without applying any patch.

The only difference you’ll find is that under Linux, the required file to edit will be(assuming you named the virtual machine LeoVM) :
/home/your_user_name/.Virtualbox/Machines/LeoVM/LeoVM.xml

Then, there you can add the required line:

<ExtraDataItem name="VBoxInternal2/SupportExtHwProfile" value="on"/>

The Leopard installation should go without a problem, and boot fine. Everything you need to know is on the guide I linked before.

Now the tricky part. Install Snow Leopard.

You should use this guide. It is really detailed and easy to follow. I used a retail SnowLeopard 10.6.3 image, and worked perfect for me. However, since the guide is for windows, you’ll need to take into account the following changes:

When you create the machine for Snow Leopard (page 13 of the guide), you need to edit the file (assuming you named the VM SnowLeoVM) :

/home/your_user_name/.Virtualbox/Machines/SnowLeoVM/SnowLeoVM.xml

and add ONLY the following lines:

<ExtraDataItem name="VBoxInternal2/Devices/e1000f/0/Trusted" value="integer:1"/>
<ExtraDataItem name="VBoxInternal2/SupportExtHwProfile" value="on"/>

Now we need to patch the Virtual Machine files. The thing is that we need support for SS3 instructions, and ACPI v.14 which is not supported by default in Virtualbox 3.1.x. If you’re using the OSE edition, you can patch the source and recompile the whole thing. However, if you’re using the standard edition, you’ll need to binary-patch the files.

You can find more information about the patches in the comments section in this post. SOME of the info is not correct, and some other is incomplete, so be careful and read everything before doing any patch. I am using the GHex to patch them.

The files to patch are:
/usr/lib/virtualbox/VBoxDD2.so
Every occurence of : 11 00 05 00
Changed for : 14 00 05 00

/usr/lib/virtualbox/VBoxDD2GC.gc
Every occurence of : 11 00 05 00
Changed for : 14 00 05 00

/usr/lib/virtualbox/VBoxDD2R0.r0
Every occurence of : 11 00 05 00
Changed for : 14 00 05 00

/usr/lib/virtualbox/VBoxVMM.so
Every occurence of: 04 C5 01 00 00 00 31 C9
Changed for: 04 C5 01 02 00 00 31 C9


I am providing the files for VirtualBox 3.1.6.r59338 HERE. Just run the patch or unpatch scripts to do the job, or open them to take a look at the files that will be copied and do it manually.

And that’s it.  You should have a Snow Leopard VM working fine. In the guide I provided you have explained how to solve the video resolution problem, which is pretty straightforward.

The network works fine, but you need to set up the static ip address for the interface, and connect/disconnect cable from the Virtualbox menu to get it working. The rest works fine. Of course it will not fly, but it is enough to try the iphone SDK under linux.

First thing was, of course see if the great Unetbootin supported OsX. Not the case.

Well then. I know it can be done with dd. Should I do anything special to do it under OsX?

Then, a simple google search will drive you to the most copied manual excerpt ever. You will see this steps in a lot of sites:

Download the desired .img file

Open a Terminal (in /Applications/Utilities/)

Run diskutil list to get the current list of devices

Insert your flash media

Run diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2)

Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2)

Execute sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img, /dev/rdiskN is faster than /dev/diskN). If you see the error dd: Invalid number `1m’, you are using GNU dd. Use the same command but replace bs=1m with bs=1M.

Run diskutil eject /dev/diskN and remove your flash media when the command completes.

Reboot (and boot from the usb device) and enjoy.

And then, if you’re like me, you will go directly to download the ubuntu image from the ubuntu server to make the process. You will go through these steps and, uh! oh!, surprise! It does not work!.

Well, give it another try. From the beginning again. Nothing. The pc does not boot from this USB drive. What the hell am I doing wrong?

Well, you are downloading an iso file, while you should be downloading an img file. Ahhh, did you think it was the same? I did. Three times. I was wrong!

Then you’ll notice that there are no img files available to download. So?. Here it comes. Run as root (sudo -s):

hdiutil convert "path/to/the/file.iso" -format UDRW -o "path/to/the/output.dmg"

Of course, the first “path to the…” should point to the downloaded iso image, and the second one to the file you want to create as this command’s output.

Now, do it again from step 2 using the dmg file instead of the iso one. It will work this time!

You can check PART I and PART II of this guide. Here, in the third part I’ll post updates, solution to problems, ans useful stuff I came across.

So basically, this third part is “what should be known”  about your kexts already succesful Hackintosh installation.

About the kexts:

(I) The process of changing or updating kexts is fairly simple. Asumming you just kept your Vanilla folder inside your Downloads folder, you just change the kexts to replace inside ~/Downloads/Vanilla/EFIkext, and then from a Terminal run:

sudo -s    (and type your password)
cd ~Downloads/Vanilla/EFIkext
./27ae.sh
./update.sh

Then reboot, and your new kexts will be loaded.

You can check which kexts are loaded typing in a Terminal:

kextstat

If your kext installations is giving you constant kernel panics, you ca debug them by booting the system, and when the chameleon appears write:

debug=0x100

This way, when you have a kernel panic, a lot of information about it will be shown on the screen and most probably the name of the conflicting kext.

Sound Kext Updates:

The sound in the netbooks is improving constantly. Although it has reached a great stability, qith a lot of internal mics now working, the sound related kexts will be probably the ones that you will update most. There is a quite stable sound kext called VoodooHDA. As you can see in the official website, the voodoohda is stalled since some months. Fortunately for us, Slice is making the hell of job with the VoodooHda project. You can see official updates here.

At the time of this writing, version 2.52 is the newest one of the voodooHDA module, so in order to update it, we download the file VoodooHDA.kext_Snow252.zip from its website, and unzip it to our Downloads Folder. Now we replace the folder VoodooHDA in our ~/Downloads/Vanilla/EFIkext folder with the VoodooHDA folder that we just downloaded and go to (I) to update the modules in the EFI partition.

About random Kernel Panics and power management:

The guy whose magic makes possible for us to have powerManagment in our netbooks is Superhai. You can find the lastest updates to his kernel extensions here.

I have found that the VoodooPower, wlthough it works under 10.6.2, it’s a little unstable causing some random kernel panics. I am using now VoodooPowerMini with much better results. I definitely advice to change to VoodooPowerMini. You can download the lastest release it from Superhai’s website and you know what to do (I).

About the fakeSMC update:

A new release of fakeSMC is out. You can download it from netkas website. It is safe and unstable. However, Prasys, from insanelywind.com has made some modifications to it spscifically for the MSI wind and clones, and it works great to, so you might want to try it. You can download it from here , and go to (I).

About the Intel GMA950 Mirroring: The Mirroring does not work. And if you don’t believed it, and you activated it, you probably messed up, because now you can’t see anything in your screen with two screens, and in one screen mode, the option to disable Mirroring is hidden.

How to solve the mirroring black lines problem with Intel GMA950 in the MSi wind? In this case Fabian Cañas will save your day! Download his app, and run it with just one screen. Problem solved!.

About VoodooBattery:

VoodooBattery is the kernel extension from Superhai that allows you to have battery readings. His extension works pretty fine, but I found that appleACPIBatteryManager has more accurate readings. You can download it from here, and go to (I).

After having all the updated kexts, I’m having still an issue I can’t find solution for. I got always a kernel panic if I start the netbook with a different USB configuration (different number of devices or in different ports), and I have to restart it a couple of times until it works. For example when I’m on the go, and I start and halt the netbook several times a never have a problem, because there are no USB gadgets on it. But when I’m at home, I have a mouse, and an external keybord. If I turn off the netbook with those plugged in, and then I start it without them, a KP will appear.

If you have any idea about what could be causing this, please enlight me!!!

In this second part of the guide, we’ll use the USB drive that we created in the PART I OF THIS GUIDE to install Snow Leopard in the Netbook. The guide continues in PART III.  The process is a bit long, but it is pretty easy to follow the indications.

As I stated in the first part, the credit does not go to me. I mainly followed a guide from a spanish forum written by Q3Soft here (spanish), which seems to be translated from a now unavailable guide on the old msiwind.net forum by 18seven and Dalton63841 (who I believe can be found now at insanelywind.com). You better go register at insanelywind.com, cause there are some files you will need to download from the forum. Anyway, it is the best place for netbook hacking so it is a good information resource.

So, Let’s Go!.

Install the OsX on the netbook hard disk

1. Plug the USB drive in and boot the netbook. Press F11 at start (F2 depending on your netbook model) to choose the booting device, and select the USB drive. The OsX Install will boot.
2. Select the Language.
3. Once the language is selected, instead of going on with the install process, select from the top menu bar Utilities->Disk Utility
4. In the disk utility, select on the left panel the netbook hard disk, and click on the Partitions tab.
5. In the Partitions tab, select 1 partition. The partition type will be Mac Os Plus (Journaled). Asign a name to the partition. I called it Hackintosh.
6. Press the Options button and select GUID partition table schema.
7. Apply changes. The resulting partition will be a little smaller that it was before formatting it. This is because the GUID partitions, uses a hidden 200-300Mb partition to handle the EFI boot and the kernel extensions. Later in this guide we’ll add those required extensions for our netbook.
8. Check that your language is correct in the upper right corner.
9. Let’s go on with the installation.  You need to select the hard disk where the OsX will be installed. If you called it like me, it will be Hackintosh.
10. Press the Customize button. Uncheck the Printer Compatibility, and check the options X11, Rosetta and Quicktime 7. Unfold the  Available Languages Node, and select only the language you’re goint to use.
11. Apply the changes, and start the installation process. It will take about 20 minutes. Remember to move around the mouse every now and then, because after 10 minutes the screen seems not to reflresh, giving the impression the computer is dead. When the installation finish, the computer will reboot itself, but it will not boot OsX. That’s because we need to install now the EFI boot system into the netbook main hard disk.
12. So, we will need once more to boot from the USB drive. As mentioned before, the USB drive must be pluged in, press F11 on the BIOS boot screen and select the USB drive as boot device. Chameleon will boot, and this time, select Hackintosh (our netbook disc) instead of the USB Drive (Install DVD) boot as we did before.
13. Select your country. Continue.
14. Select your keyboard type. Continue.
15. When asked if you want to transfer information from another hard disk, or time machine, answer NO. Continue.
16. Enter your registry information, or whatever comes to mind. Continue.
17. Some more questions you should answer. Computer placement and so. Continue.
18. Create the user account. Use a password. Continue.
19. You should be able to see the OsX main desktop now. A lot of things will not work, so it’s better not to start playing with it yet, but don’t worry, we’ll fix all of this.

Install the EFI Boot system on the netbook hard disk

20. We’ll need this four files (Contact or leave a comment if any link is dead):
    • Chameleon 2.0 RC3 r658: A newer version of Chameleon. Brose the right side of the website for releases, and select the file: Chameleon-2.0-RC3-r658-bin.tar.gz
    • Vanilla.zip:  Some kexts.

    Unzip all these files into your Downloads folder. Then you can delete the zip files if you want.

21. Open a Terminal (Applications->Utilities>Terminal)
22. Type:
    sudo -s
    hit enter, and type the password of you user (the one that you created in step 18). Do not pay attention if you see somehing like Error 35 in the output. This will give you root permissions until you close the Terminal, so don’t do it, ok?
23. Let’s see how are our disks called. Type in the terminal:
    diskutil list
    You will see 2 hard disks. One of them will be probably called disk0, which will have a GUID_partition_scheme and it will have the capacity of your netbook hard drive. This is our main hard disk. You will see that it has a partition called Hackintosh (or the name we selected). It will have, just before the Hackintosh partition, another one without name and of type EFI. This will be where we’ll install the booting system. Write down the identifier of this partition. Probably disk0s1.
    The other disk that you see, will be the USB drive that you have plugged in, which you can identify by the BOOTLOADER partition in it that we created in the first part of this guide.
24. So, assuming from now on that the EFI partition of the last step was called disk0s1 type in the Terminal:
    newfs_hfs -v EFI /dev/disk0s1
    This will format the partition with HFS filesystem.
25. Now we need to mount somewhere this unit to start adding things there. In the Terminal:
    mkdir /Volumes/EFI
mount_hfs /dev/disk0s1 /Volumes/EFI
    Now it should be accesible from Finder.
26. We need to create some folders. Create a folder called Extra and hanging from this one, two folders called Extensions and Themes. In the Terminal:
    mkdir -p /Volumes/EFI/Extra/Extensions
mkdir /Volumes/EFI/Extra/Themes
27. Now we need to install chameleon into this partition. You should have unzipped the chameleon tar.gz file into your Downloads folder. So, from the Terminal:
    cd ~/Downloads/Chameleon-2.0-RC3-r658-bin/i386
fdisk -f boot0 -u -y /dev/rdisk0
dd if=boot1h of=/dev/rdisk0s1
cp boot /Volumes/EFI
28. Load more chameleon files into the EFI partition. From the Terminal:
    cd ~/Downloads/Chameleon-2.0-RC3-r658-bin/Optional\ Extras
cp -R smbios.plist Themes /Volumes/EFI/Extra
29. Unmount the EFI unit. From the Terminal:
    umount -f 7Volumes/EFI
rm -rf /Volumes/EFI
fsck_hfs /dev/disk0s1
    You should see in the output: The volume EFI appears to be OK.
    Now this is the default EFI boot system. Now you need to setup the specific kernel extensions to support your netbook.

Install specific kernel extensions for MSI Wind/Akoya and clones

30. First thing we need is to setup the UUID.kext file.It must be filled with your MAC, a number that identofies your wireless card. Click on the upper apple icon on the toolbar, and click on About this Mac. Click on the left menu the Network section. If it is empty, it means that your wifi card is not currently detected by OsX. This is expected in the Medion Akoya E1210, and in the Advent 4211B. If this happens to you, you probably will have a Realtek RTL8187SE card which comes bundled with a lot of netbooks. You’ll need the Realtek utility both to operate the wifi card and now, to get the MAC and configure the UUID extension. Proceed to next step.
    If by chance, you see here your wifi card, and you can see its MAC congratulations. Your card is well detected by OsX. Proceed to step 33. Personally, I bought from Ebay a Dell 1500 wifi card (BCM4312) and it works like a charm jsut by adding a PCID to the native airport driver. I would definitely advice this.
31. Ok, so you have one of the RTL8187SE card?. Well go here and download the driver. Just unzip, install and reboot. Do not unplug the USB drive!. If you do, you will have a kernel panic because your netbook’s hard drive EFI boot is not ready yet. Press F11 on the BIOS boot screen and select the USB drive as boot device again. Chameleon will boot, and you’ll select Hackintosh again.
32. Now your card should be detected, and it should automatically start the realtek utility. In the “Link Status” tab you could see your MAC, as well as in the Profile Explorer we opened in step 30. Just write it down.
33. Now in Finder, go to Downloads/Vanilla/EFIkext/ and right click the UUID.kext file. Select “Show package content”. We need to edit the file info.plist.
34. Oen info.plist in the text editor, and locate the long numeric chain ending with 0016174EE065. Replace this number with the MAC address you wrote down. Save and close the text editor.
35. Now we need to edit the ooting device ID. To do so, open Disk Utility (Applications->Disk Utility) and right click on the Hackintosh (or whatever you called it) partition. Select Information. A window will appear. The string that we need is the Universal Unique Identifier. Copy it.
36. Now go to Downloads/Vanilla/boot.plist and edit the file com.apple.Boot.plist. Locate the <dict> tag. We need to paste the next text just after it:
    <key>boot-uuid</key>
<string>HERE THE STRING THAT YOU COPIED</string>
    Maybe you get a syntax error when you save the file. Do not worry about it. It is normal.
37. Ok, almost there! Now, there’s a script in your Vanilla folder that will patch the intel GMA950 driver to fix the resolution in your screen, and another one that will update the kexts in the EFI partition and rebuild the kernel cache. You need to run those scripts now, and after every OsX update that could touch any driver. In the Terminal:
    cd  ~/Downloads/Vanilla/EFIkext
sudo -s (and enter your password)
./27ae.sh
./update.sh
    It will take some time to finish.
38. Now let’s update the boot.plist file. From Terminal:
    cd ~/Downloads/Vanilla/boot.plist
./update.sh
    You’ll only need this script now.
39. Now let’s mark the Hackinsosh partition as active. Assuming that the netbook hard drive was disk0 (you can check it again using “diskutil list”). From the Terminal:
    fdisk -e /dev/disk0
    And answer the questions with:
    p
f 1
w
y
q
40. Now you can unplug your USB drive (eject it from the desktop first) and reboot your computer. It should reboot just fine, with proper resolution, and without the help of any external drives.

The sound

41. First, download the OsX86Tools, as we’ll need it later. Now, the original guide suggested to download the VoodooHDA.kext and install it though OsX86Tools to make the internal mic work. (Start OsX86Tool, Select Install Kext, and select the just downloaded VoodooHDA). However I think this step is not necessary. In the Vanilla Folder you downloaded, I already introduced the Slice’s VoodooHDA, which has some improvements over the standard voodooHDA. So by now, it should be already loaded in your system and working:D. The only thing that we need is to setup the correct levels on the Prefpane that comes with the Extension.
42. To setup the Prefpane, go in Finder to Downloads/Vanilla/Prefanes/VoodooPrefs/ and double-click VoodooHDA.prefpane. Select Install for all users. The pane will be installed, and accesible from the OsX Settings panel. You can now play with levels to see which fit your needs.Setting up “speaker” and “recording” level at max level , and “monitor” at mid level should work.

Tweaking “About this mac” info

43. If you want to modify some of the information in the About this mac screen for aesthetics purpose, you can do it through the OsX86Tool. Start it,  and select “Modify About This Mac”. You can set the CPU string, and the RAM info to match your netbook.

The trackpad preferences pane

44. Macs have a great trackpad that our netbook has not. But we can make the trackpad config pane to appear in the settings pane with a simple tweak. This will work in the Medion Akoya E1211 for sure. I can’t tell about the others. Edit the file /System/Library/PreferencePanes/Trackpad.prefPane/Contents/Info.plist (you’ll need root permissions, so fire a Terminal, type “sudo -s” whithout the quotes, and launch “TextEdit” again, without the quotes from the Terminal and delete these two lines in the file:
    
<key>VendorID</key>
<integer>1452</integer>
    Now the panel will appear in the OsX Settings pane, and you will be able to customize the parameters.
45. If you’re still with me your hardware should be working fine. Webcam, wifi, ethernet, keyboard and trackpad, video resolution. All of it. To check the camera, fire ichat with the webcam turned on. To check that CoreImage and Quartz Express are working, just start FrontRow. If it works, it is working fine.

Updating Snow Leopard to 10.6.2

46. Now we need to update OsX to 10.6.2. The main problem here is that from 10.6.2 the Intel Atoms processors are no longer supported, so if we just update using the software updater and reboot, the computer will not boot and we’ll have a nice Kernel Panic. Fortunately some russian guys patched the kernel to allow 10.6.2 work almost vanilla in our netbooks. You could always use the 10.6.1 kernel, but, the new one seems absolutely stable, so why not update? First download the kernel from here (at the end of the post you’ll see the links) or here. It contains a single file. Unzip the file in your Downloads folder, and rename it mach_kernel_10_6_2.
47. Dowload the C10.6.2 combo update from apple website to your Downloads folder.
48. Let’s make a backup of our actual kernel.From a Terminal:
    
sudo -s             (and insert your password)
cp /mach_kernel /mach_kernel_10_6_x
49. Now install the combo update, but (and there’s not enough bold here) DO NOT REBOOT THE COMPUTER AFTER THE INSTALLATION FINISH.
50. Now restore the 10.6.1 kernel. Well check that everything in the OS is fine with a reboot. From the terminal:
    
cp /mach_kernel /mach_kernel_10_6_2_original
cp /mach_kernel_10_6_x /mach_kernel
51. Now, as we said before, we run the kext patching scritps:
    cd ~/Downloads/Vanilla/EFIkext
./27ae.sh
./update.sh
52. Now you can reboot. Everything will go just fine. Now you’re running 10.6.2 with the 10.6.1 kernel. Your system should be stable, but anyway we’ll use the 10.6.2 kernel.
53. Basically, what we’ll do is to replace the 10.6.1 kernel with the patched 10.6.2. Besides that, there’s an important kext that we should update as well, because it changed for 10.6.2.So, assuming you unzipped the kernel into your Downloads folder, run in a Terminal:
    sudo -s   (and type your password)
cp ~/Downloads/mach_kernel_10_6_2 /mach_kernel_10_6_2patched
    (this way we will keep all the kernels in /. The 10.6.1 (renamed 10_6_x), the 10_6_2original, and the 10_6_2patched.
    cp /mach_kernel_10_6_2patched /mach_kernel
cd ~/Downloads/Vanilla/EFIkext
mv SleepEnabler.kext ./_Disabled/SleepEnabler_10.6.1.kext
cp -R ./_Disabled/SleepEnabler_10.6.2.kext ./SleepEnabler.kext
54. Again, we run the kext patching scritps:
    ./27ae.sh
./update.sh
55. And that’s it. Congratulations. Reboot and enjoy. You’re running 10.6.2 in your netbook. Everything should work by now. It’s been a long process, but once it’s done, you can enjoy an almost Vanilla system, without scripts patching things over there like other OsX86 distributions. Your netbook only loads some kexts at start, but the rest of the system remains untouched, making safe for further updates (executing the scripts as mentioned before, and just restoring the kernel if the update has changed it).If you find any mistake in the proces or any  dead link please leave a comment.

Update: There’s a Third Pard of this guide. There I post some kernel extensions updates that will make the netbook even more stable, and maybe will solve other problems that you may face. Take a look at it to see if something helps you.

As you will see, the system is almost completely Vanilla, except a couple of kext modules.

The credit does not go to me. I mainly followed a guide from a spanish forum written by Q3Soft here (spanish), which seems to be translated from a now unavailable guide on the old msiwind.net forum by 18seven and Dalton63841 (who I believe can be found now at insanelywind.com).

In this first part, we’ll see how to create a USB (pendrive or hard disk) from the Snow Leopard DVD image. This USB device will be used in PART II OF THIS GUIDE to install Snow Leopard in the Netbook. After the install, we’ll make a few changes to leave the system as stable as possible, and we’ll update some kexts with newer versions in PART III.

To start we will need a 8GB or more USB device, the retail image of a Snow leopard DVD or the DVD itself and a Mac.
If you don’t have a mac (neither do I) you can make a quick install on your netbook with the WindOsX (google it, is a Leopard DVD ready to install) and create the Snow Leopard USB device using your netbook.

If you don’t have the Snow Leopard retail DVD image, but you do have the DVD itself, you will obviously need an external USB DVD Drive to make the install.

Let’s Start!

1. Connect the USB drive on the Mac and fire up the fisk utility. We are going to format the usb drive. The utility is pretty straightforward, so no further explanation is needed. We need to  make 2 partitions. The first one should have 200Mb. The next one should have at least 8Gb. If the Usb drive is bigger, you may want to make another partition for data. It is important that both partitions are Mac OS+ Journaled, and the Partition Schema must be MBR.
   Call the first partition BOOTLOADER. Second’s partition name is not important.
2. Now select the Restore tab and drag the image of the Snow Leopard DVD (or the DVD itself) to the Source text box. Now select our freshly created second partion in the pendrive as Destination. Check the “Erase Destination” Checkbox. Let it finish.
3. Once we have the Snow Leopard Installed in the 8Gb partition of our USB drive, we need to install a bootloader in the small one. We’ll use Chameleon R2. You can download the package from the Chameleon website.
   The file that we want is Chameleon-2.0-RC2-r640.pkg.zip. This version has proven to work flawless for me, although there are newer version available. Just extract the installer and start the installation of the bootloader. Eventually the installer will ask for a target partition. Select BOOTLOADER, our 200Mb partition. Finish the installation.
4. Now open a Terminal. and write: (BOOTLOADER is the label used to you bootloader partition)
   sudo -s
/usr/bin/vsdutil -a /Volumes/BOOTLOADER
5. Now we need to mark the active partition. To do so, we need to know the system’s identifier for this partition. On the terminal run:
   diskutil list
6. Get the identifier of the Bootloader partition. To do so take a look at the output of the last command. You will see one disk (/dev/disk1 or /dev/disk2) that will have 2 partitions, one with the bootloader 200Mb long, and the other with our 8GB partition. Write down the BOOTLOADER partition identifier in the right most column. For example, if it was disk2 and first partition, the identifier would be disk2s1. In general we will have a code like diskXsY, being X the disk and Y the partition.
   Now in a terminal run:
   fdisk -e /dev/diskX   (change the X for your disk number obtained before)
   The answers that you need are in sequence:
   p
f Y    (change Y for your partirion number obtained before)
w
y
q
7. Now you need to download this file. Unzip it in you Downloads folder so the paths written here would be the same for you.
8. You need to create 2 directories in the BOOTLOADER partition, inside the Extra folder: Extensions and Themes. If the Extra folder does not exist just create it. To do do so, run in the Terminal:
   mkdir -p /Volumes/BOOTLOADER/Extra/Extensions
mkdir /Volumes/BOOTLOADER/Themes
9. Now, it chameleon had any default text (probably not) we need to delete them. From a Terminal:
   rm -R /Volumes/BOOTLOADER/Extra/Extensions/*.kext
10. Now we copy the new files to their appropiate places in the BOOTLOADER partition. From a Terminal:
    cd ~/Downloads/USBboot/
cp com.apple.Boot.plist /Volumes/BOOTLOADER
cp -R *.kext /Volumes/BOOTLOADER/Extra/Extensions/
    (Notice that the ~ symbol refers to your home dir. You coud replace it with /home/yourusername)
11. Now we update the extensions cache and the com.apple.Boot.plist. To do so, from a Terminal:
    cd ~/Downloads/USBboot     (in case you left the directory)
chmod +x update.sh
cp update.sh /Volumes/BOOTLOADER
cd /Volumes/BOOTLOADER
./update.sh
12. And that’s it. Your USB drive is ready to install Snow Leopard into a hard disk. If you start your computer from the USB drive, now chameleon should start.
