My motherboard: MSI K8N Neo4-FI/Platinum (MS-7125)
Chipset: nVIDIA nForce4 Ultra, AMD Hammer

I see.On MSI alc850 works. On my asus no...

No alc850 sound on my ASUS A8NSLI SE either, I could never get it to work. Not in Tiger, not in Leopard, no matter which AC97 kext I've tried. It appears in the preferences pane but will not render any sound.

As soon as I boot the DVD it says: "system config file 'library/preferences/systemconfiguration/com.apple.boot.plist' not found. Has this happend to any one? I'm using an Acer Aspire 5520-5912.
One thing that I saw is that when I explore the DVD from vista it only finds eight file which are less than 1 Mb.

It's really strange that it works fine on my A8N-SLI and not on SE, Premium or Deluxe models. What's the damned difference????????

Here's a tutorial I found on a spanish forum, sorry for the typos, I'm latino:

Step 1: Going down :P

>>Start Windows
>>Go to Control Panel and open your Device Admin
>>Search for the Sound device (AC'97 something) and double click it.
>>Go to Details and write down these numbers:
VEN_XXXX mine is 10DE
DEV_XXXX mine is 0059
>>Reboot and get the hell out of there


Step 2: Back to heaven :)

>>Start Zephyroth's Leopard :D
>>Open a terminal
>>Login as admin (sudo su)
>>Go to this folder:
/System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/AppleAC97AudioIntelICH.kext/Contents
>>nano Info.plist
>>Find this line: <key>NVIDIA AC97 Audio</key>
>>Below you'll see something like this: <string> 0x026b10de 0x005910de blahblablah </string>
>>Add your vendor and ID here this way:
0x(here your dev ID)(and here your vendor) in my case it's 0x005910de
>>Save with Ctrl+o and exit with Ctrl+x
>>chown -R root:wheel /System/Library/Extensions
>>chmod -R 755 /System/Library/Extensions
>>Reboot and check for audio output

Hi,

I have downloaded & burned the DVD but when i boot from it
Its boots till the point where GUI should load and appearers
but the GUI never load it just show a light blue screen to me
I waited it for to come for some 20-25 min....

Is this normal ?? do i have to wait more !!

Hi prateesh,

Blue screen is not normal. Try to boot with -v to see what error you'll receive and than check the forum to see if there is a solution to that error.

Looks like it wants to use the other video output (external ) happends with my Q45.

First of all, I'd like to join everyone and thanks Zephyroth for all the time he puts in this project. This release is awesome.

I installed 10.5.2, and everything seem good so far.

My specs:
OS X: Leopard 10.5.2 R1 by Zephyroth
Board: EVGA 131-K8-NF44-AX NF4
Memory: 2GB OCZ Platinum
CPU: AMD Athlon 64 X2 4800+ Toledo
Graphic: MSI GeForce 7800 GTX 256 (now working with NVInject 0.2.1/10.5.2 kext also QE/CI)
Integrated Audio: AC97
HD: WD 160GB
DVD - IDE CW-8123-C Slot Drive from iMac

My install options:
MBR formatted in DISK UTILITY, Kernel 9.2.0, EFI (MBR), Forcedeth.kext, NVidia+NVinject, Azelia Audio (removed), NForce Chipset

The first time I used the AC97 but it didn't worked, so I tried Azelia, and it didn't worked either. From there I just deleted Azelia, and use the ALC850-Install.zip floating around, and this time it kicked in :).

BTW, I tried to use my Pioneer SATA DVD drive first to install from the DVD but got a "Waiting for root device" stuck. Using a IDE slot drive picked from a broken iMac here worked like a charm (just a bit noisy).

Any Solution for to make it look for my laptop's default display
