Finally I got it to work on my PC as well.
I messed up my 10.5.8 installation, so I "had" to get 10.6 to work..
And I finally did!

I used your old guide tho.
And my vital part was the "First Boot: - turn on your computer and go to Boot Menu (F12) then choose 8GBsnow as the first boot then press enter, on the Chameleon menu choose your hard drive with recently installed snow and boot with -v -x32 (very important), it will boot in verbose mode displaying lots of text, if all goes well you will greeted with SnowLeopard intro video but no sound yet, just continue the process until you reach your desktop."

That made me able to finish up everything.

I had a problem installing Chameleon 2 RC1 on the SL Disk tho.
So I had to manually install it.

Also, my Network-cards dont work in 64bit, only 32bit (atleast it seems so atm.)
I got a DLink DWA-556 (PCI-E N Card) and a DLink DWA-140 (USB N Card)
Both uses Ralinks chipsets, so I guess thats why.
If anyone get a hold of some working drivers for 64bit from Ralink. Please, do tell :-)

Thanks a bunch for the guide. After a week of struggling, blood, sweat and tears. I finally made it. Boy, what a ride!

Edit: Now it seems that my Ethernetadapters have given up on me.
They wont work in 32bit now. sigh

Edit Again: I did a reformat etcetc. and installed everything from scratch. Except that I kept one SL install alive to modify everything.
Installed. Used the -x32 in the boot.plist, and now everything seems to be working allright
I just used OSX86Tools to enable Quartz (I allready had my 9600 GT 1GB String in the boot.plist)
and it seems to be working quite allright.
I just got a shocker when it said "boot: error" on my Chameleon boot. But I restarted, and it was allright. wierd tho.
Anyhow. All fine and dandy now! :-D

I'm going to try installing SL tonight w\ this thread's original tutorial and the information bzen has provided. The only thing I don't quite understand is where I obtain my UUID. I've read up on it and I understand what it is and why it's needed but don't know where to find it.

Thanks for explaining about mkexts, I also found rebuilding the mkext helped me avoid kp when installing little snitch.

go to utilities and open "Disk Tool" or "Disk Utility" or whatever its called in English (Im using Norwegian so..)

Then rightclick the device you want the UUID of and click information.
There the UUID will be shown. Its a long number, so you most likely will have to make the window bigger.

Ok, but won't I need the UUID prior to the installation of OSX? Right now I don't have OSX in any form on my drive so how would I be able to use the disk utility to obtain the UUID?

First thanks for this detailed guide. Unlucky me, I've got a noobish problem:
I preparded an USB Device as explained, but I cannot make my PC to boot from it. After pressing F12 to go to Boot menu I select "Hard Disk". Now I can choose between my usual Harddrive and "Bootable Add-in Cards". Theres no USB device to choose from...
I tried it with iPod (8GB) and USB Stick (2GB + Retail DVD, your linked method)

Any solutions?

Got a PCI NIC for GA-G31M-E2SL (Dynex DX-PCIGB at bestbuy for $22) it has Realtek8169 chip on it. It has built in support under IONetworkingFamily.kext under Plugins and RTL8169 DeviceID 10EC8169. So after a bit of digging around and trial error finally found that need to edit DSDT.

The one with original post will create issues with any PCI NIC as it has GIGE defined in PCI Express Slot 1. My actually card for this board comes up on Hub0@1E (bottom PCI Slot) top is slot 0 (have DGE-530T in there that could not get to work). Can find this out with IORegistry Explorer Utility (have attached).

So decompiled the ASL from Original Post to DSL file. Then editted. Had to remove the GIGE and then all GP9 Ref's with Text. After did this was able to check with bootable USB and finally with 64 Bit Kernel.

Now have pretty much vanilla install (from what I understand) with Rev 2.0 Board. I have attached all relevant info and DSDT files (compiled/uncompiled) and some reference material used FYI.

Have to turn on legacy storage support in USB, then should see in boot menu when hit F12 or in BIOS under boot drives before saving change.

Thanks for your response. So I went to BIOS and saw that i already had "Legacy USB storage detect" enabled. A picture of my BIOS is attached below. I've found no solution yet...

Don't use F12... hit delete on power up and go into Bios, Advanced section I believe and highlight your USB drive and use page up to move it to the top. I never could get F12 to work either. Just remember to change it back when you're done or you may run into issues during normal boot.
