What you will need:
1. A working OS X Installation: Leopard. 10.5.7 Leopard GUIDE by ihavearedcouch or a distro (ex. Kalway) --- just use Kalway, search for it...it installs w/o hassle. you might get kernel panics, but just keep restartin computer until it boots up.
2. Retail/Beta copy of Snow Leopard 10A432.
3. A HD to install Snow Leopard on.
4. Airwalk's EXTRA FOLDER - Click to download
5. Airwalk's DSDT.aml - I prefer you create your own so it specifies your own hardware.
6. Chameleon RC3 - Click to download
7. SET YOUR BIOS SETTINGS: TO ENABLE, ENABLE, AHCI MODE + IDE, AHCI MODE - just the jmicron stuff
8. Check NOTES in the bottom of this post for extra stuff you might need...
9. Apple Combo Updater 10.6.2
This installation will take about 1-3 hours tops so be patient. it'll even take a whole day if you dont know what your doing...
Step 5: Now we need to make/edit the boot.plist file located in the EXTRA folder. Open up the apple.boot.plist and replace the text with this:
<key>Kernel Flags</key>
<string>busratio=20 -x64 boot-uuid= 93F4654A-DEAC-3A5D-9FB9-4AAF355BAD3D</string>
Also audio works natively with airwalks DSDT.aml with his LegacyHDA kext.

As a 1st timer I will note a few things that I encountered with my EVGA X58 Classified (E760) board. With the lasted bios installed. 1st this guide is excellent to get you a long ways. I made a few mistakes along the way and it took me about a week of 12 hour days to get me back on track. This is with reading I did along the way about dsdt's and becoming a forum member to 8 other forums, LOL.
Step 1: It says a disto of Kalyway 10.5.7 but if all you can get your hands on is a copy of 10.5.2 then that works great too. That is what I used. Don't bother trying to upgrade to 10.5.7 though, it didn't work for me and it is a waste of time. With 10.5.2 I had internet and that was excellent to download and read what I needed to without going back and for between my PC.
4. Airwalks DSDT.aml was the same as mine in everyway even though I have some different drives and more ram and different vid card.
Step 6: Is now
Chameleon 2.0-RC4
I love this little program.
I confirmed that you don't need "busratio=20" in the boot.plist file. BUT you need the -x64, nothing else. To confirm once your OSx boots go to the apple, select About This Mac, select "More Info" and go to Software, in the System Software Overview it will tell you whether 64bit kernel is running or not.
Or open Terminal and copy and paste:
ioreg -l -p IODeviceTree | grep firmware-abi
In reality you may be changing between this depends on how you want your computer to function. For example using a 64bit photographic program in 64bit mode will give you about 30% faster results. BUT as I discovered I lost 3ware Raid. My Ethernet that I had running is gone. Audio doesn't matter because that wasn't working for me anyways. It's funny because you can use a slightly different code that everyone running a regular Mac has to use anyways because every new Mac except for the Xserver's run at 32bit by default.
So in your boot.plist you enter
arch=-386 for 32bit
or
-x64 for 64 bit
or
arch=x86_64 also does 64 bit mode.
Is it worth it, I don't think so. Why? You can get more or less the same use of your RAM as long as you make sure the 32 bit box is unchecked. (see photo).
When I get 64bit drivers for my necessary stuff then I will switch.
