The GA-EP43-UD3L Motherboard, and how I installed Mac OS X Snow Leopard 10.6

OK, this is not going to be a real guide, just kinda notes, info, and stories
on how I installed OSx86 10.6 Snow Leopard on my system.

Well lets start with the system specification and background info.

-System Specification-

Case = Antec Two Hundred
Motherboard = GIGABYTE GA-EP43-UD3L
CPU = Intel Pentium E6300 Wolfdale 2.8GHz
Memory = A-DATA 2 x 2GB DDR2 800
Hard Drive 1 = WD 320GB SATAII 8MB 7200RPM -- Windows 7
Hard Drive 2 = WD 500GB SATAII 16MB 7200RPM
Hard Drive 3 = Seagate Barracuda 7200.11 500GB
Hard Drive 4 = WD 500GB SATAII 16MB 7200RPM
Hard Drive 5 = WD 500GB SATAII 16MB 7200RPM -- Mac OS X
Video Card = Nvidia GeForce GTS 250 512MB, XFX GS250XYDFC
Power Supply = Antec Earthwatts EA-500 500W
Monitor = Dell E151FPp 15", Dell E177FP 17", Epson PowerLite 77c Projector @ 75"
OS = Windows 7 64bit, Mac OS X 10.6.2

I use the BIOS to select the hard drive I want to boot, that cuts down
on potential problems, and makes things a little bit easier to install,
you just install like you would if each OS is the only OS installed,
and the trick is to unplug all other hard drives before the install,
leaving only the hard drive you want to use, plugged in, that also
keeps you from messing up, or loosing data.

I did not want to use a distro for fear of them being tampered with,
so I looked for a different solution and found Lifehacker's guide, I
did have to install a distro "temporally" for the thumb drive part,
and that told me OSX would work, but then I tried to install using
the thumb drive and all I got was a garbled screen, I was never able
to make it work, I also tried Empire EFI and it did the same thing,
so I kept reading.

Some things I tried made it lock up, at a black screen, but most just
made white lines or blocks on the screen, I learned that it may be the
video card that was giving me problems, so I borrowed a video card
out of my girlfriends computer and it worked, no acceleration, but
it worked.

I kept trying to get acceleration to work, I messed up the install
countless times when trying, I learned that video cards with a
"non reference design" could cause problems, sure enough both of
my video cards were "OC editions", factory overclocked, here
are the two problem cards.

ATI HD 4850 512M, MSI R4850-512M OC - gave me a blank or garbled screen every time
ATI HD 4830 512M, MSI R4830-T2D512 OC - worked for install, no acceleration, was never able to get acceleration

I want to note that I "think" I remember seeing that at least one
person got the MSI R4830 working, I was just never able to.

I wasted about a week on trying to get it working, and decided to
just say fudge-it, and just get a Nvidia video card, so I ordered a Nvidia
GeForce GTS 250 512MB, XFX GS250XYDFC
, and in about 10 minutes
after installing the card I had acceleration, the first thing I tried was
"EFI Studio", and it worked good, but the version of EFI Studio that I
used did not have GTS 250 listed, but it did list the 9800 GTX,
basically the same thing, and that's what I used, I later went with a
DSDT for my motherboard and let PC EFI auto detect my video card.

BTW I dumped the ROM from the card and ran it threw NVCAP Maker
and it came back like this.

Nvidia GeForce GTS 250 512MB "XFX GS250XYDFC" with 2 DVIs and TV out


I also want to note that both displays work, but not mirroring, and
that I had to install some freeware called "SecondBar" to give me a
second menubar for the second display, it works OK, but not with
everything and its a little buggy, just thought I would bring it up,
might help some of you.

Basic Install

OK there are 2 different ways of installing that I tried, both seamed to
work, one was easier than the other.

The first way to install

Lifehacker's guide, or more like a mod of it, we would start at "Launch
the Disk Utility application on your borrowed Mac
" and stop before
the Terminal work,

-Two notes-

(1) Use "Mac OS Extended (Journaled)"
(2) Instead of the "Terminal work" download the "myHack Installer" and
install to you thumb drive

Then set the BIOS to this

(1) MB Intelligent Tweaker, leave it alone, just make sure it's correct
for your CPU

(2) Standard CMOS Settings,
"Floppy 3 Mode Support" set to Disabled

(3) Integrated Peripherals,
"SATA AHCI Mode" set to AHCI,
"Onboard IDE Controller" set to Disabled
"Onboard Serial Port 1" set to Disabled
"Onboard Parallel Port" set to Disabled
"USB Keyboard Function" set to Enabled
"USB Mouse Function" set to Enabled

(4) Power Management Setup,
"HPET Mode" set to "64-bit mode"

Then you install Mac OS X Snow Leopard 10.6.

After the install, you install the "myHack Installer" to your hard disk

The second way to install

Download "Empire EFI", burn it to CD,

Then set the BIOS to this

(1) MB Intelligent Tweaker, leave it alone, just make sure it's correct for
your CPU

(2) Standard CMOS Settings,
"Floppy 3 Mode Support" set to Disabled

(3) Integrated Peripherals,
"SATA AHCI Mode" set to AHCI,
"Onboard IDE Controller" set to Disabled
"Onboard Serial Port 1" set to Disabled
"Onboard Parallel Port" set to Disabled
"USB Keyboard Function" set to Enabled
"USB Mouse Function" set to Enabled

(4) Power Management Setup,
"HPET Mode" set to "64-bit mode"

Then boot the CD, wait for the boot Screen, and then eject the CD,
wait about 30 seconds, swap the CD with the Mac OS X Retail DVD,
and wait for about 60 seconds now, then press "F5", and then select
your Mac OS X Retail DVD and install.

After the install, you install the "myHack Installer" to your hard disk


(1) Video not working

If its an ATI card, it may be "non reference design", or it could also be
your motherboard, during boot you have a few seconds to hit "TAB",
hit it two times then you can type in some options.

(A) PCIroot "-pci1" or "-pci0" tells the computer were the video card is.

(B) Verbose Mode "-v" lets you see the error messages.

You would hit Tab two times and type "-pci1 -v" and hit enter, or type
"-pci0 -v" and hit enter one of them might allow use your video card
or at least see the error message.

(2) Sound not working

Try this, its a AppleHDA.kext modified for ALC888

[GUIDE] Retail Snow Leopard (10.6.2) Install on Gigabyte GA-EX58-UDR3
(Core i7), Fully working 100%, ALC888 v1.8.3fc1 Included

(A) Find "AppleHDA.kext", back it up, and remove it from "/System/Library/Extensions"

(B) Download "AppleHDA.kext" from the above link, look for "ALC888"

(B) Find and download "Kext Utility"

(E) Drag "AppleHDA.kext" onto "Kext Utility" to install

BTW I was using VoodooHDA but it caused a kernel panic
after the 10.6.3 update

(3) Acceleration not working

(A) First edit the "" in "/Extra", and add this


(Hint) You can copy "" to your desktop, edit it,
and copy it back into "/Extra"

This turns on auto detection of you video card, does not always
, you may also have to add "-pci1" or "-pci0" under
"Kernel Flags" like this, even then it may still not work.

<key>Kernel Flags</key>


<key>Kernel Flags</key>

(B) If Nvidia, Download EFIStudio and try that.

(C) If ATI, You could try dumping or downloading the ROM for your
video card and look here for info on how to use the ROM

And you can get the ROM from

Or use GPU-Z under Windows to retrieve your ROM, and name it
, and put in into the /Extra folder

-- read --

You would edit your "" in "/Extra", and add -useatirom
some ware under "Kernel Flags" like this

<key>Kernel Flags</key>

(D) Try another video card

(4) Bonjour not working

Go to Realtek's web page, and WOW there are Mac drivers, down
at the bottom of the page

Realtek Software: Drivers & Utilities

I would edit and disable auto setup of the network
just incase it causes problems with the newly installed driver

Like this


BTW if after installing the Realtek drivers your Hackintosh locks up
when downloading Torrents/P2P, or playing online games like WoW,
its a well known bug that even affects real Macs, the only way I have
been able to fix it, was to use the network settings and driver installed
by the "myHack Installer" but that also means no "Bonjour"

Here are some Links

WoW LEOPARD USERS: Current Issues & Resolutions

Transmission causes leopard slow death


I am not going into details, instead I am just going to point you to a
place were to download your own, and how to use the Ubuntu Live
to get your own, and give you a few notes and tips

Head on over to and
find your motherboard.

(Note) Its were I got the DSDT I am using now, I just added the fix to show
the SATA drives as internal.

- you need to register in order to download, and you put the
"DSDT.aml" into the "/Extra" folder

To make your own using the "Ubuntu Live CD", open the "Terminal", type in

"cd Desktop"

and then

"sudo cat /proc/acpi/dsdt > dsdt.aml"

save the "dsdt.aml" on your desktop to a thumb drive

- go here for a better understanding -

Now you just need to patch it, and for that you need to do a lot of reading

-A few notes-

(A) A DSDT can be different depending on how its dumped

- If your running on OSX, using a hacked dsdt.aml
- If you extract from a downloaded BIOS file
- If you extract from a running system, not using a dsdt.aml, like Linux

Its best to extract on a running system, one that is not using a dsdt.aml file, "no DSDT injection"

(B) There is an awesome DSDT editor over at

Hints and tips

(A) Use Time Machine to back up your system, saves you a lot of
trouble, you will need to reapply any hacks or modifications after
a restore.

(B) Save a copy of your modifications, tools, web links, documents
and notes on the install, to a thumb drive.

(C) Install the "myHack Installer" to a thumb drive, or burn a copy
of "Empire EFI" and keep it handy.

(D) Install most modifications, hacks, and KEXTs into the "/Extra"
, if you screw up, you can reboot with "myHack Installer"
installed to a thumb drive, or "Empire EFI" and fix it easily, else
enjoy doing a system restore or a reinstall.

(E) DOCUMENT WHAT YOU ARE DOING, save it in a text file or something,
believe me, it will end up saving you time and headaches.

(F) Check out the guides for the the "GA-EP45-DS3L" motherboard,
they are almost exactly the same.


1. (A) North Bridge: Intel P45 Express Chipset for the GA-EP45-DS3L
(B) North Bridge: Intel P43 Express Chipset for the GA-EP43-UD3L
2. South Bridge: Intel ICH10


1. Realtek ALC888 codec
2. High Definition Audio
3. 2/4/5.1/7.1-channel
4. Support for S/PDIF In/Out
5. Support for CD In


1. Realtek 8111C chips (10/100/1000 Mbit)

I/O Controller

1. iTE IT8718 chip

Just remember to use the correct DSDT for your motherboard,
not a DSDT from another.

(G) Do you want to run Windows applications under Mac OS X ?

(1) VirtualBox, over at for free.

(2) CrossOver Mac over at Codeweavers, $39 to $69

(3) Parallels over at for $50 to $80.

(H) Want to run brand new Windows games ?

Unless you are trying to play games like Bejeweled, go setup
a dual boot. (Note) Parallels and CrossOver Mac will play older
3D games just fine, stuff like Unreal Tournament, Serious Sam,
and such, and setting the game to use OpenGL seems to give
better results

(I) Having trouble editing or changing a file,

Drag it to the desktop, make the change or edit, and copy it
back you might also want to make a backup copy.

(J) Web Cams,

There is a driver that supports a few hundred different web
cams over at

Macam, USB webcam support for Mac OS X

(K) Xbox 360 Controller.

It works just fine with Mac OS X, get the driver at - Mac OS X, Xbox 360 Controller driver

(L) Some Applications (like emulators) store ROMS, BIOSes,
configuration files, and other files inside themselves, right
click on the file and select "Show Package Contents" to show
the files and directory's

The ZIP file I uploaded has my DSDT and CODEC dump inside, It
works just fine for me, but it may not for you, if not, you are going
to have to make your own, sorry.
