So first i wanted to thank Verdant of insanelymac forums, that guy is a god among men and then also i wanted to thank dj nitehawk he made it so much easier to do this whole process .i adapted alot of there guides to make this one, so big props to them

Ok time to get started
Things your gonna need

* A working Leopard partition [if you need help with this keep reading]
* 8GB Flash Drive
* DMG or Retail Disc of snowlepoard
* P5N-D Pack [http://www.mediafire.com/download.php?ntddzjzemn1]

Ok so if you need help getting a working leopard partition don't fret its really simple.
If you don't need Leopard Skip To the "DSDT!"

Installing Leopard
first get iPC 10.5.6 [make sure you use this nforce patch][http://pcwizcomputer.com/ipcosx86/?p=176]
Format your hard drive into two partitions using GUID and make them Journaled
Name one something like Snowleo and the other Leo
Under patches pick

Video
You decide
Chipset
Nforceata [the slashhack one]
Fixes and Patches
CPUS=1
Applications
EFIstufio
OSX86 tools

install and then use
10.5.7 to update
yay! now [hopefully] your running 10.5.7



DSDT!

Copy the DSDT folder to your desktop

Then Open Terminal and type this in

HTML Code:

 cd ~/Desktop/DSDT_Patcher1.0.1e
 ./DSDT\ Patcher

Choose 0 for darwin

ignore any errors and if it doesnt work then use -f

now download DSDTse
http://www.kexts.com/view/78-evosx86_dsdt_editor.html

Use this to edit the DSDT.dsl that you have

Now change the Length in the Device (RTC) section in the dsdt.dsl file from 4 to 2.


Example

HTML Code:

Device (RTC)
                {
                    Name (_HID, EisaId ("PNP0B00"))
                    Name (ATT0, ResourceTemplate ()
                    {
                        IO (Decode16,
                            0x0070,             // Range Minimum
                            0x0070,             // Range Maximum
                            0x00,               // Alignment
                            0x04,               // Length -> change 0x04 to 0x02
                            )
                    })
                    Name (ATT1, ResourceTemplate ()
                    {
                        IO (Decode16,
                            0x0070,             // Range Minimum
                            0x0070,             // Range Maximum
                            0x00,               // Alignment
                            0x04,               // Length  -> change 0x04 to 0x02
                            )

the reason we did that was becuase, it fixes the CMOS reset bug.

now copy that dsdt.dsl to your desktop and then run

HTML Code:

cp dsdt.aml /Users/"your username"/Desktop/DSDT.aml

OK, So now you should have your DSDT.aml [case sensitive].

email that to your self, just incase. because you are gonna need that and its not fun to remake.



Preboot

I am using PRE-INSTALL AUTOMATOR v1.1
but its already in the p5n-d pack because i put in the right kexts

Restore the retail "Snow Leopard Install DVD" to a read/write disk partition (hdd or usb flash drive)
to do this:

use disk utility and click your flash drive or hard drive [NOT the one you are installing snowleo to]

Then click restore at the top and then drag the Disc/DMG in the source section and drag the drive to the Destination
PROTIP: if you are having trouble ripping the disk to the drive, then just rip the disk using the create option and it will create a DMG on your desktop of the disc

Drag the contents of Autoinstaller 1.1 to the desktop

then open the folder snow-installer

then double click installnow to run it

then pick your flash drive or hardrive

MAKE SURE you pick the right drive.

then copy the folder "snow-installer" to the flash drive

then copy the DSDT.aml to your flash drive and then make another copy of the DSDT and put it in your "snow-installer\filez\Extra" on your flash drive


Installation

Restart the computer and boot into the flash drive or harddrive

After the retail installer loads, click "Utilities" > "Terminal" in the menu and type the following to run the script again:

HTML Code:

/snow-installer/installnow

and now this time pick where you want to install snowleopard

after thats done close terminal and Make sure you pick that same drive and install snow lepoard

pick customize and uncheck everything [dont worry, we will put them in later]


POST INSTALL
reboot into your leopard partition once again

copy that DSDT.aml into your /extra folder in your snow hardrive

Reboot into your snow hard drive now, set it all up

get the sound drivers from here

get the pref pane + kext
http://www.insanelymac.com/forum/ind...owtopic=175372

now go into your /extra/extensions folder and find the "NforceLan" and "IOnetworkingfamily" extensions.

take those two and drag them onto the "Kext Utility.app"

do the same with the VooDooHDA.kext and double click the prepane

open the "optional installs" folder in the flash drive and install x11/printer/languages and whatever else you need


run disk utilites and fix disk permissions

reboot

Your Done

Thanks for the guide--newbie here, trying to install OS X on my P5N-D(Q6600, 8GB RAM, ATI 4890) and I got through the 10.5.6 install process successfully, then installed 10.5.7 and booted onto the SL USB drive. But when I get to it, it seems it isn't recognizing any other hard drives attached to the computer--so it says SL requires the computer already have 10.5 installed on it (which it does). From here I can choose to Restart or Restore from a Time Machine backup...clicked time machine to try to access terminal to try and do it from there, but again it doesn't see my drives so it won't work. It returns "diskutil[158:903] _CFGetHostUUIDString: unable to return UUID for host. Error:35"

Any ideas why it can't see my hard drives??

Steve

Thx for sharing surely will help ;D

Dont know if anybody even looks at this thread anymore, but im curious as to what chipset drivers your using. I ended up having to pull the ones out of my leopard install (AppleNForceATA) to get it to quit waiting on root device. Unfortunately those don't seem to be the answer though because now if I try to move any large files or do a time machine back up they cause a crash. Any feed back on it would be appreciated.
