GA-EP45-UD3L Snow Leopard Install Guide v1.0 for Newbies

 

PREFACE

 

I had been in Hackintosh field for last six eight months or so. Tried several distros and learnt a lot in this field. When I first used the Mac OSX I loved this system and plan to buy an original Mac very soon, as a result of my personal experience. I recommend all other Hackintosh users to OSX and if they love it, go and buy an original one. I don’t claim any credit for the procedures specified in this guide, all credit goes to relevant authors (whose links are given) and I am thankful to all of them for any guidance and help they provided. My aim for writing this guide is to compile all procedures / things / useful links for Snow Leopard in one place for easy reference.

 

MY SYSTEM SPECIFICATIONS

 

Motherboard Gigabyte EP45-UD3L with onboard Gigabit Ethernet RTL8111 and Azalia ALC888

Intel E8200 Core 2 Duo Processor 3.0 Ghz

Graphics Zotac Nvidia Geforce 8800GT 512MB

RAM 4GB (1066)

Hard Drive SATA 1TB with GUID partition

DVD: SATA based

Keyboard & Mouse both are USB based (try avoiding PS2 keyboard & mouse, as Mac don’t like it)

 

PRE-REQUISITES

 

Although it is not necessary to have a running OSX 10.5.x, but if you have it is good to use it to get some key information about your system before attempting the Snow installation. e.g. Use IORegisteryExplorer to find information about your Ethernet, Sound and Graphic Card, and generate a fully working DSDT.aml (even before installing the SL) for used in SL for flawless operation. But you can try this direct approach using this guide.

 

BIOS SETTINGS:

 

Gigabyte has just released the latest version of BIOS for this motherboard. So, I would recommend download and install the latest version F7 before you proceed. This is also necessary to note down BIOS settings because of following reasons

 

  1. when you attempt to install Snow Leopard, on every reboot it will reset the BIOS and you had to change all these settings manually (unless you apply CMOS fix, which I will describe later on).
  2. by changing the BIOS settings, we are trying to make it more comparable with Mac Hardware. e.g. Snow Leopard only accepts SATA AHCI settings, so in BIOS we change RAID/SATA settings to AHCI and in some cases even disable onboard IDE Controller to go even more close to real Mac system. Another good example would be USB based Keyboard and Mouse (which Mac uses so we change BIOS and use USB based mouse not PS/2 based.
  3. the AHCI handling is much faster in F7 bios as compared to F4.

 

Following are the settings in this BIOS:

MB Intelligent Tweaker:

CPU Clock Ratio=9x (rest of the things as per default, CMOS reset makes it 8x)

 

 

Standard CMOS Features:

Drive A= None (CMOS reset enables it)

Floppy 3 Mode Support= Disable (rest of the things as per default, CMOS might enable it)

 

Advance BIOS Tab”

First Boot Device=CD ROM (CMOS reset makes it Floppy)

Second Boot Device=Hard Disk

SMART=Enable

Limit CPU to 3=Disable

No Execute Memory=Enable

C1E=Enable

C2/C2E=Disable

CPU Thermal Monitor=Enable

CPU EIST Function=Enable

Delay for HDD=0

Full Screen Logo=Disable (CMOS reset makes it Enable)

Backup BIOS Image to HDD=Disable

Init Display First=PEG

 

Integrated Peripherals Tab:

SATA RAID / AHCI Mode=AHCI (CMOS reset makes it Disable)

SATA Port0-3 Native Mode=Disabled

Azalia Codec=Auto

Onboard LAN=Enable

USB Controller=Enable

USB 2.0 Controller=Enable

USB Keyboard Support=Enable

USB Mouse Support=Enable (because I use wireless USB Keyboard & Mouse, CMOS reset makes it Disable)

USB Legacy Storage Detect=Enable

Onboard IDE Controller=Enable (if your system keeps rebooting upon reading the Boot CD, change it to Disable)

Onboard Serial Port=Disable (CMOS reset changes it to default)

Onboard Parallel Port=Disable (CMOS reset changes it to default)

 

Power Management Tab:

ACPI Suspend Type=S3

PME Event Wake up=Disable (CMOS reset makes it Enable)

Power on by Ring=Disable (CMOS reset makes it Enable)

Power on by Alarm=Disable

HPET Support=Enable

HPET Mode=64bit (CMOS reset makes it 32bit. If you want to run SL on x64, change it to 64bit)

Power on by Keyboard=Disable

Power on by Mouse=Disable

 

PnP/PCI Tab:

Both PCI1 and PCI2 IRQ Assignment=Auto

 

FILES YOU NEED FOR ISNTALLATIONS

 

(Thanks to 3rr0rists for providing the method)

  1. Snow Leopard Retail DVD. I suggest to buy it as $29 is not too much.
  2. Snow Leopard Boot CD Download Here
  3. Snow Leopard Kext Download Here
  4. Bootloader (Chameleon V2.0 ��" RC3 r658) for snow leopard Download Here
  5. OSX86 Toosl for EFI strings of graphics, audio, ethernet etc. Download Here.
  6. DSDT patcher for generating DSDT.aml Download Here
  7. iaslME for decompiling and recompiling DSDT.aml Download Here

 

INSTALLATION METHOD

 

  • Insert Snow leopard Boot CD to your DVD Drive and boot from it.

If you are unable to boot from DVD or get the BIOS read error when booting, switch your PC Off for atleast 10 seconds, switch it on, press Del key and go into BIOS make sure that settings are as suggested (AHCI mode is enabled and if you again unable to boot, just disable Onboard IDE controller).

If you don’t want to waste your blank CD on this, you can use a jump drive to start with. To use this method you must have a working OSX 10.5.x and then you need to do as advised by 3rr0rists in reply to my question. Thanks 3rr0rists once again for the simple and short guide.
for USB device, format USB with partition map MBR and format with HFS+, install Snow Bootloader to USB and copy all kext to folder “Extra” in USB” boot with USB device connected and select your USB device. and follow the guide...

  • When chameleon logo appear, eject your snow leopard Boot CD then insert your DVD DL Snow Leopard Retail and press F5.
  • Select your Snow Leopard DVD (Macintosh Install DVD) and type “arch=i386″ (without quote) to get 32 Bit, if you want get 64Bit SL just press enter.
  • Installation like usual, first create partition for Snow Leopard and must in GUID Partition and install, just uncheck language Translation and Printer Driver to take some space HDD
  • And Install, after finished installation. reboot, and eject your Snow Leopard Retail DVD and replace with Snow Leopard Boot CD again and then boot from cd.

When you boot, you will have to Press Del key and go into BIOS, as Snow Leopards has rest your CMOS/BIOS. So go to your BIOS. Again make changes as suggested above. Save changes and exit from BIOS. Here I suggest Power Off your PC for a while. Then Switch it on. Now place the Snow Leopard Boot CD to boot.

 

POST INSTALLATION WORK

  • Boot With Snow Leopard CD Boot, when chameleon logo appear, select your Snow leopard partition and type : “arch=i386″ (without quote if you want to boot in 32bit mode, if you don’t enter anything, it will go automatically into 64bit mode. Also remember the BIOS setting if you have set it to 32/64bit) and following on screen.
  • Install Snow Leopard Boot Loader
  • Click on Go -> Computer -> Snow (name of the disk) -> Extra and copy all Snow Leopard Kexts and Extensions folder from download location to this Extra folder.

 

EFI STRING INJECTION METHOD FOR GFX, ETHERNET, AUDIO:

 

Quickly check if all important hardware is working in SL e.g. Check internet for Ethernet working, open iTunes and play something to check your sound, open dashboard and add a gadget to it. If you get water waves effect, it means that QE / CI / GL of your graphics card is enable, otherwise you need to work on it too. I got Ethernet working out of box. But graphics (Zotac Geforce 8800GT) was not giving me QE/CI/GL support. So I used OSX86 Tools for this for injecting EFI string to boot process (this way there is no need to use and load the kext and booting time significantly improves).

 

  • Inject EFI strings for devices (graphics, Ethernet and sound (if available)

 

Although Mac Gurus don’t like so called EFI Injectors, but if you are new to SL and don’t wana go the detailes of DSDT.aml then check if you could get your graphics, ethernet and audio working through EFI injection using OSX86 Tools. This is the easiest way to get most of the things working (although my sound card ALC888 did not work through this method, so I had to do DSDT method, still doing research to enable sound in this motherboard). Well I agree with Mac Gurus upto some extent in this regard, but my idea is first to run SL without any problem and then do the improvements like creating and editing DSDT.aml for various devices etc.

 

  • Run OSX86 Tools. Click on “Add EFI String/Boot Flag” button. First click on graphics card, from the drop down menu, choose your graphics card, it will give you hexadecimal EFI string in the bottom section. Then click on 2nd icon on top row “Import String to Boot Editor” After that you will have to click on button at the bottom “Apply changes to com.apple.Boot.plist”. Similarly do it for your Audio and Ethernet Strings. A quick tip here, you will not be able to see the effect unless you reboot. So when you next time boot, again check the QE/CI/GL for your graphics (by adding a gadget in dashboard, if you don’t see a clear water waves effect, again run OSX86 Tools, and click on “Enable/Disable Quarts GL” button of upper left side. Enable it. Again reboot and you will get the QE/CI/GL enabled for Nvidia GF8800GT card.

 

DSDT METHOD OF ENABLING DEVICES (If you don’t like EFI Injection method):

 

Generate DSDT.aml by following method

 

  • Open the DSDT Patcher folder, and double click the DSDT Patcher icon. When it say press any key to continue, just enter. Then it will ask you “Which OS to emulate? [0=Darwin, 1=WinXP, 2=WinVista]. Press 0 and enter for Darwin based OS. 99% this gives you a DSDT.dsl file in the same folder of DSDT Patcher. This is a text editor file and we can change it in a text editor (if we need to do it). This patcher already applied the Snow Leopard’s CMOS reset fix for you. So you don’t have to worry about. Pay attention to the text appearing in this program window when it says “Process Completed”. If you get any error or warnings, then contact your best friend (google.com) for the help to remove these errors. If you get 0 error and 0 warnings, its ok to proceed.
  • In 2nd step we will edit it if we need to. If you want to edit DSDT.dsl file to have the codes for Ethernet and sound etc. You need to follow this guide.
  • Suppose you get no errors and no warnings and you don’t want to edit .dsl file. Next step is to compile this DSDT.dsl file to get a DSDT.aml file. Open the folder which contains the iaslME application. Open the DSDT Patcher folder also which should be having your dsdt.dsl file. Now drag and drop dsdt.dsl file over the iaslMe application icon. It will automatically generate a dsdt.aml file for you and will store it in the “Sessions” folder. Go to DSDT Patcher folder, then Open Session folder, then a folder which will be having most recent date and time as name of the folder. You will find two files; one will be dsdt.aml and other will be log.
  • Now you right click on dsdt.aml and choose Get info -> Name and Extension. Change the name of the file from dsdt.aml to DSDT.aml. (as this file name is case sensitive). Now copy this file and past it in the Extra folder. It might ask you to authenticate it with administrative password.
  • Final Step: Remove the Snow Installation DVD and reboot the system. Again press Del key go to BIOS and load the recommended settings for the last time (as you have already put DSDT.aml file in Extra folder which is having CMOS reset fix) and then save and exit from BIOS. Switch off your computer. Switch it on and you will get the Snow Leopard fully working (hopefully).

If by using DSDT.aml method still you are unable to use some of your devices, then you need to convert DSDT.aml into DSDT.dsl using iaslMe (just drop the DSDT.aml over the application icon) and edit the DSDT.dsl using text editor. For details I would recommend searching google for your problem, as I am also new in this particular technique and will not be able to help you much. Suggested links are in my reference section.

 

SOME ISSUES:

 

Automatic USB Device Removal:

I discovered this issue in SL. My USB based attached hard drive is automatically ejected and a message appears “Disk was not ejected properly. If possible always eject a disk before unplugging it or turning it off”.

Solution:

I did a research for the solution. Found a solution on Apple’s Official forum. Solution is simple: Go to System Preference->Energy Saver and there you will see a check box saying “Put the Hard Drive to Sleep when possible”. Simply uncheck that box.

 

Audio in this motherboard (ALC888):

I tried everything but could not get the sound working for ALC888 chipset even by using tmongkol guide by using DSDT editing and LegacyHDA.kext for ALC888.

Solution:

So I looked for alternate solution. Found a really cheap USB based sound card with virtual 5.1 CH sound track, power amplifier inside, recod function etc for just USD:3.90 from Hong Kong. Cheapest shipping is around $8 so I ordered it over the internet. According to seller its Mac ready and no drivers are required in any OS (windows, Linux and even Mac). I haven’t received and tested it yet, but will update this guide about the performance and quality of this sound card in SL.

 

NTFS Read/Write Support in Snow:

Apple does not like NTFS file system, so apparently there is no direct way of getting read and write access to NTFS volumes. Yes, NTFS volumes are visible in Mac OSX but they only provide you read only access. If you try to change the permission through Get Info, it will not allow you to do so.

Solution:

In 10.5.x versions I was using NTFS-3G application / drivers to get read and write access to NTFS volume and it was working perfectly without any issue. However, recently I found this article which describes that Snow Leopard seems to include read/write support for NTFS partition, however its disabled by default. All you need to do is enable it. A command line method to enable native read/write access in SL is described there on this forum. I havn’t tested it yet (I will definitely do it and will update this guide about it when I have time), but another forum warrned of possible NTFS volume corruption using this method. So use it on your own risk

 

Sleep and Wakeup:

System sleeps instantly without any extra delay. But …… I unable to wake it up.

Solution:

Not yet found.

 

SOME USEFUL COMMANDS:

How to Remove the old mkext file in /Extra/Extensions- Open Terminal and run following commands:

 

1. Execute this on a shell sudo chown -R root:wheel /Extra/Extensions

2. Execute this on a shell sudo chmod -R go-w /Extra/Extensions

3. Execute this on a shell sudo kextcache -v 1 -t -l -m /Extra/Extensions.mkext /Extra/Extensions

 

 

How to Clean the System Caches- Open Terminal and run following commands:

 

1. Execute this on a shell sudo rm -fr /Library/Caches/*

2. Execute this on a shell sudo rm -fr /System/Library/Caches/*

3. Execute this on a shell sudo kextcache -v 1 -t -l -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions

 

USEFUL REFERENCES:

 

I searched web for running my SL smoothly and found very good forums / postings / links which I have booked marked and would like to thank all respective authors for their contribution and especially 3rr0rists:

1. What is Kext, Where is kext, how to install kext . Thanks to insanelymac for this article.

2. Understanding kexts. Thanks to Prasys’ Blog for this article.

3. ALC889A, Gigabyte, Vaious AppleHDA.kexts are available. Thanks to tmongkol for guide.

4. Removing errors and Warnings from DSDT files. Thanks to its author.

5. ACPI DSDT Table. Thanks to Donnerstag for this article.

6. OSX Terminal Commands. Thanks to its author.

7. How to apply DSDT. Thanks to insanelymac for this article.

8. A simple introduction to building a DSDT. Thanks to blackosx for this post.

9. Quartz Extreme and Core Imaging in Snow Leopard. Thanks to Prasys’ Blogh for this post.

10. KextHelper b7, a very good utility to install kexts (in S/L/E), I am not sure if you can use it to install kext in E/E folder.

 

FINAL REQUEST:

 

I am not a mac expert and consider myself as a novice in this field, so I would request all Mac Gurus and experts to help me in improving this guide and correct me if I am wrong somewhere. I have a couple of un-resolved issues on this motherboard like sound (ALC888) not working tried every method. After DSDT editing my system profiler is able to see a device but my system preference does not show up any output or input device to select. If some one could guide me step by step how to get it working in a simple and detailed manner that would be great. 2nd issue is wakeup from sleep. If someone could also help me how to fix that, it will make this guide perfect. Thanks for reading this guide.

There is something I don't understand by now. This motherboard is nearly identical to GA-EP45-DS3L. I have had success installing SL on this one, including sound. Have you tried blackosx's guide ?

I think it should run.

Anyway yesterday I bought an UD3L one and I will have a try following your method first. I will tell you something. I think it is very important working with DSDT.

 

Thank you very much for everything. I will tell you my improvements. :)

Although i have snow running... i like testing and i am gathering info for a dedicated UD3 guide...

 

I have a UD3, UD3L and UD3P and will test your CD with these... the DS3L CD works fine with my board also, but i get a KP during install... The CMOS issue seems to affect the UD3 more...

 

I can assist you with the guide if you wish, as i have a mediocre knowledge of OSX etc

Thanks for the reply. In first attempt I tried it and used kaolala's patcher. but to do the cmos fix i need to edit dsdt.aml generated by patcher and I was getting error that ACPI table terminated in middle when converting dsdt.aml to dsdt.dsl. Anyhow then I followed tmongkol's guide. Now I was able to do cmos fix and edit dsdt file for sound. After that My sys.profiler was able to detect the sound card, but sys.pref.sound was not showing any devide for input and output. Then again I came back to kaolalal's way of generated dsdt.aml and simply loaded it in Extra folder and I got the sound working as I was trying tmongkol before that and already put the LegacyHDA.kext in E/E folder. Now updating my guide with the new procedure. Thanks for the suggestion.

 

By the way any suggestion to improve the guide is always appreciated.

I installed 10.6 this morning and having exact same issues (no wake up after sleep, no audio).

 

Did you try this audio fix yet?

 

Also I've noticed OSX does see my audio card but nothing is available in list of Outputs and Inputs (maybe its because I have nothing connected to audio outputs yet).

 

Any luck with waking up from sleep?

 

Another minor issue I have is my IDE CDROM is not visible as well as IDE controller. Did I miss something in BIOS configuration?

 

thanks!

I tried like 10 different method to enable audio - nothing works. I can see audio device in System Profiler (Device ID: 0x1458A002, Audio ID: 66) but nothing is available for Output and Input.

 

Please post detailed instruction on how to fix audio if you have it.

 

thank you.

I suggest you remove the download link for the Snow leopard. It is against forum rules...

 

replace it with something liek

 

Get a copy of snow leopard from a store or something

either a full install disk (in the boxed set) or upgrade disk (if using an upgrade disk, leopard needs to be installed on that disk...)

Thanks for the input. I do have a mediocre knowledge of OSX as in this field since May this year. But I learned a lot by doing research over internet and reading various forums. So yes, till now I am able to get sound from this motherboard, applied SATA fixed, and applied USB auto eject fix to my DSDT.aml. Currently updating my guide. Hopefully will release it in next week during my off time.

Yes I have tried audio fix and able to get sound. Now my ALC888 is recognized by system profiler and my System Preference / Sound gives me option to choose the output / input devices. Please see my reply to above posts. I basically used windows based DSDT Patcher by Koalala and then its detailed explanation was found in a PDF v 1.4 in post by BlackOSX (My thanks to both of them for providing very detailed guides). Still fighting with wakeup issue and will update you people with that too.

 

Windows based DSDT Patcher

 

BlackOSX Guide

 

Hi I am updating my current guide and will give you updated one very soon, just waiting for my off days.

 

Thanks everybody.

 

 

 

 

what about running it on a EP45-UD3LR ... will it run on this also ? I'm running almost identical setup, besides the motherboard and I'm running a raptor disk instead.

 

I am pretty much sure it will work on EP45-UD3R. Make sure not to enable RAID through BIOS or during installation of OSX.

 

I tried like 10 different method to enable audio - nothing works. I can see audio device in System Profiler (Device ID: 0x1458A002, Audio ID: 66) but nothing is available for Output and Input.

 

Please post detailed instruction on how to fix audio if you have it.

 

thank you.

 

This mobo gave me really tough time in enabling sound, but I finally enabled it. See my reply to above posts and you will see two links one for the Windows based DSDT Pathcer and another for downloading the PDF guide 1.4 for using that patcher. After getting that DSDT.aml I need to edit it for various things, but it gave me sound. I used LegacyHDA.kext by tmongkol for ALC888 SL ready. I am using yellow color file which is basically for 4out2in regaular headphone. I will update my guide very soon.

PLEASE HELP.

 

I am getting quite frustrated. I have successfully installed SL on my EP45 UD3L. Graphics seems to be working as I get the ripple affect when I add a widget. Sound does not work but I really dont care at this point...

 

My ethernet is not working. Now I am no network specialist so maybe this is something ridiculous that I am missing. I have a linksys wrt54g wireless router hooked up to my cable internet (DCHP) and i run the ethernet from the wireless router into my rig. My wireless is fine as Im working on my MBP right now.

 

This is my setup:

 

Mother board: Gigabyte EP45-ED3L

 

Video card: Gigabyte 9500GT Ultradurable2 over DDR3

 

Processor: Intel E7400

 

Hard drive: WD 1TB (SATA2/8M)

 

Ram: Samsung DDR2 2G PC2-6400 (x2)

 

I installed SL using the USB method without any problems using Chameleon (not the newer version) I tried using osx86tools to inject the efi stings for ethernet then I tried the method using the dsdt patcher and iasme with no success.

 

My bios is updated to the F7 and all the specs are followed to what was listed as far as i can tell.

 

When I try and open Safari, i open network diagnostics and my ethernet is green, network settings is yellow and isp is green. I scoured the internet trying to see if this was something network related but I couldnt find my problem. Im thinking that it might be as most people have had ethernet working right out of the box. Ive gone through all the network assistant and diagnostics, restarted the modem and nothing...

 

Also, I tried putting the computer to sleep and it shutdown... is that a problem that goes along with this problem that I am having?

 

Any help would be GREATLY appreciated.

 

Thanks.

 

If I have left out any info that would help diagnose my problem please tell me.

I am pleased to announce I have a full working SL system including audio.

 

My system is:

GA-EP45-UD3L F7

Intel E6300 Core2DUO

4 Gb RAM

Nvidia GeForce 7300 GS 512 Mb

 

Therefore I have first made a DSDT.aml including ethernet, graphics card and sound card using ACPI Patcher Beta 5 in windows. After that I have modified it with iaslMe to fix CMOS reset.

I have made 2 partitions, one including chameleon and the other with Mac OSX Snow Leopard.

Everything has worked fine from the beginning without any kernel panic.

I have performed an installation following blackosx's guide and using his ds3l boot cd as I had done before with my other EP45-DS3L motherboard.

 

I am very happy now !!! ;)

Good morning:

 

First of all take it easy. It requires a little patience. I have had success because of luck and experience with my first motherboard GA-EP45-DS3L wich is nearly identical to these one.

The most important think is to build a DSDT.aml. I have read a little and your graphics card is not included in ACPI Patcher Beta 5, the program I use to make a DSDT.aml. Therefore I suggest first to build a DSDT with only ethernet and sound card included and graphics card should be put in com.apple.boot.plist.

As said before, I have followed blackosx's DS3L's guide using his Boot CD and a retail Snow Leopard DVD in a second partition. In first partition I have installed Chameleon and I have put in Extras folder exactly the same kexts I used with my DS3L.

By now it runs everything perfect in Snow Leopard 10.6.1 (updated).

Only issue is sleeping wich does not run well, but that is something does not matter very much for me.

 

Try first what I have said and ask anything you want if I can help you !!

 

Good Luck :D

As said before, I have followed blackosx's DS3L's guide using his Boot CD and a retail Snow Leopard DVD in a second partition. In first partition I have installed Chameleon and I have put in Extras folder exactly the same kexts I used with my DS3L.

By now it runs everything perfect in Snow Leopard 10.6.1 (updated).

Only issue is sleeping wich does not run well, but that is something does not matter very much for me.

 

Try first what I have said and ask anything you want if I can help you !!

 

Good Luck :D

 

Will any of the info in this topic help me with installing SL onto an EP43-DS3L? I'm a bit of a newbie with this stuff and don't exactly know what the difference of the ep45's and UD3L's and all the variation that are out there. Other than I know that some have either the alc888 like mine or the alc889. I have 10.5.8 up and running 100% on my machine right now, but it was much more simple installing that than it is with SL, at least it seems that way. I also have a Linksys WMP300N wireless card and a ATI Radeon 3450 video card. Any info to help me out would be greatly appreciated.

I noticed you removed the download link for snow... However, you could point out that the $29 copy is a UPGRADE, and therefore, requires leopard to be installed on the snow destination drive.

 

Wrong.... I bought the 5 user 'Upgrade" of Snow Leopard and did a fresh install with no Leopard anywhere, a blank HDD. It functions as a standard DVD.....

Thanks for the help. Could you point me in the right direction to find how to build a proper dsdt.aml file for my ethernet? Thanks again.

 

Good morning:

 

First of all take it easy. It requires a little patience. I have had success because of luck and experience with my first motherboard GA-EP45-DS3L wich is nearly identical to these one.

Hey Community!

 

After long research I finally foundthis Guide and decided to use it, due to it's clear arrangement.

 

I builded my PC a week ago and intendedto install snow leopard to it. I had iDeneb 1.4 already running, butonly for testing the hardware. So in uninstalled it and was nowtrying to install snow leopard based on this guide.

 

I knew there would be issues, butstupidly they begin much earlier than expected:

 

I am not able to boot from the SnowLeopard Boot CD.

 

So as this seems to happen more often,i followed the advice:

 

„If you are unable to boot from DVDor get the BIOS read error when booting, switch your PC Off foratleast 10 seconds, switch it on, press Del key and go into BIOS makesure that settings are as suggested (AHCI mode is enabled and if youagain unable to boot, just disable Onboard IDE controller)."

 

Done, BUT no change!

 

I uploaded three pictures of the BIOS dialog:

my hardware:

 

  • Gigabyte ep45-ud3lr updated to F7 and Bios settings as described in the guide
  • 1 TB Samsung HD103UJ SpinPoint (SATA)
  • Sony Optiarc AD7240 (SATA)

  • Intel C2Q Q9400
  • 2x2048 ram (installed on red-slots)
  • Ati radeon 4870<LI>Be quiet 500w PSU

Any help would be really appreciated!

Well i got a upgrade disk shipped to me, and if leopard is not installed on the disk, it says something like

 

"You cannot install Snow Leopard at this time as the inserted disk is an UPGRADE disk, therefore Leopard needs to be installed first..."

 

It then gives me two options,

Restore from a time machine backup or Restart...

 

Interesting no???

heh.. never mind my earlier post.. i've managed to boot to snow from boot cd and then made the snow partition bootable and copied the extra extensions and all..

 

i've inserted my own custom nvidia strings on efi for my card and it works like a charm, i've got sound for the damn alc with one 64bit voodoohda instead of 8 other solutions, just delete the applehda and replace with voodohda and the little script for the terminal not to show up on every boot and you are perfect! :D (but no input)

 

The only think i'm missing and i can't get to is the damn DSDT, i'm stuck on WAK and something and i just can't understand what to do next, any pre-compiled dsdt with cmos fix to test..?

 

my specs.. and info...

Working Retail Snow Leopard 10.6.1 (no DSDT)

Mobo GA-EP45-UD3LR F7

CPU Core 2 Duo E8400

RAM Kingston 4GB PC8500 1066MHZ HyperX

VGA MSI N250GTS Twin Frozr 1G OC (EFI)

One Sata 2 disk with 1 Snow partition (and another 100gb one hidden for later use)

Sound Voodoo HDA 64bit (ACL888 & ALC889)

you can try this... Its for UD3p, but works on my UD3...

 

It is generally not a good idea to share dsdt files, as they are very system specific...

 

The attached one has 8800gt built in though... so its not perfect (im trying to get rid of it or replace it with my 9800GT one...)

 

 

and you need to make it DSDT.aml (without the copy.)
