What you need:
- MSI Wind
- SnowyWindOSX.iso (can be downloaded here- (EDIT- search for Snowywindosxalpha on Google and you should find what you are looking for )
- Single-layer or dual-layer DVD
- External DVD drive

Instructions:

1. First of course you need to burn the iso. It will fit on a single layer dvd.

2. Put in the disk and power on, then tap F11 to get to the boot menu. Choose the SnowyWindoSX Alpha.iso. It does take about 4-5 minutes to boot the disk, don't worry, that is not the case with the final install.

3. Once booted up, choose the language, click continue, and agree on the licence.

4. Click on Utilities on the menubar, and click Disk Utility. Create and/or format your partition as Mac OS Journaled. It can be MBR OR GUID.

5. Close Disk Utility and choose your partition.

6. Click Continue. Do NOT click customize. It is pointless. There is nothing on the list to customize.

7. When you get to the Install button it will check the disk, you can skip it or not.

8. After it is finished, Reboot back into the disk, choose your language, and then click Utilities on the menubar and click Terminal.

9. In terminal, type:

cd /Volumes/MacOSXInstall/fix
diskutil list (This will give you the disk and partition number for your Mac install)
fdisk -f boot0 -u -y /dev/rdiskX
dd if=boot1h of=/dev/rdiskXsY
fdisk -e /dev/diskX
p
f Y
w
y
q

(X=disk number from diskutil list)
(Y= partition number from diskutil list)

10. Now reboot and boot into your newly installed Mac. Note that sound and graphics won't be working at this point.

11. Once booted into your fresh install, mount SnowyWindOSX Alpha on your desktop. Look in the Optional Installs folder for the 10.6.1 update. Install it, but DO NOT REBOOT.

12. In the Optional Installs folder there is a package called Update Handler. Install that package. Then stored that package on your hard drive. It will handle future updates in this same manner.

13. Now you can reboot into your perfect system.

14. If at this point you do not have full graphics, look in the Optional Installs folder. Read the Read Me file. It will explain the use of EVERYTHING in the folder.
