i installed Snow Leopard (Retail Install DVD) on Intel DG31PR successfully with DellSnow cd from superhai's DellSnow (i used DellSnow.iso v0.5)

updated to 10.6.2 and got sound works now...
for usb to work i've added
<key>USBBusFix</key>
<string>yes</string>
into com.apple.Boot.plist (Library/Preferences/SystemConfigurations)

in case any one have 9400gt 1gb dvi/vga/hdmi i used these step described in tonymacx86 froum, just follow the exact step:

With your 9500 GT, I'd try NVEnabler64.kext. If that doesn't work- here is my workaround for the 9400 GT. You inspired me to lay it all out there- here goes...

ENABLE DUAL DISPLAYS & MIRRORING IN 10.6.2 WITH NVIDIA 9400 GT - 64-BIT
I've tried everything from DSDT to EFI Strings to device id patching to editing NVEnabler, but the only thing that works is to replace your vanilla graphics kexts with 10.6.1 graphics kexts and use BOTH NVEnabler64 and NVEnabler in System/Library/Extensions.

1. Download http://dl.dropbox.com/u/3315703/10.6.1% ... 0Kexts.zip
2. Download NVEnabler and NVEnabler 64 from http://www.projectosx.com/forum/index.p ... c=370&st=0
3. Open Kext Helper b7
4. Drag all kexts into Kext Helper b7 (should be 11 in total)
5. Type your password and click EASY INSTALL.
6. Close Kext Helper b7.
7. Open Snow Leopard drive.
8. Drag /System/Library/Extensions folder onto Kext Utility
9. Open Applications/Utilities/Disk Utility
10. Highlight Snow Leopard in the left column.
11. Click Repair Permissions.
12. Restart computer.

NOTE: My specific card has DVI/VGA/TV-OUT. There are only 2 channels on these cards though- 1 is DVI and 2 is VGA/TV-OUT. You can't use VGA and TV-OUT at the same time. I'm using a DVI to VGA converter and S-video to my TV.

With a 1 monitor setup, I can enable QE/CI a number of different ways and use the 10.6.2 vanilla kexts, but the only method to get mirroring and TV-OUT (S-video) is this way. If you come up with a better solution let me know.

Good luck- this should work with the 9500 GT- but try just NVEnabler64 first- it may work without all of this stuff !!

My favorite installation for SL on this mobo is http://osx86.sojugarden.com/ .
This is a super clear retail installation that worked. Attached find my DSDT fixed with no errors nor warnings.Extract and put it in the /Extra folder.
In the BIOS, Disable Auto mode on the HD section.
