Okay, when I did this install, I lacked somewhat clear info on what to do, on my specific board, so I decided
to do this guide for everyone else with a Asus P5Q SE board, as well as an XFX Radeon HD 4890 GPU.
Stick to the guide, and it will work - I guarantee it 99,9 % (since some things can be wrong somewhere, that I
didn't encounter on my setup)!
You can see my rig in my signature
Prerequisities:
Intel CPU
Sony Optiarc optical drive
clean SATA HDD - which means no partitions
iBoot disc
Snow Leopard 10.6.3 retail disc
Multibeast 3.9.1
Combo update 10.6.8 ver. 1.1
the 2 kexts I have linked for in the bottom of this guide
Kext Helper b7
Kext Utility
What I did was:
1: Make sure you have BIOS version 0803 for P5Q SE - flash it in EZ Flash through BIOS menu
2: I took backup of any crucial data to my second harddrive - then I disconnected it, both power as well as SATA cable.
EDITED INFO 15-03-12
I just did a re-install, to try this:
When booting with iBoot, first go into BIOS and disable your other harddrive(s) in BIOS, save settings and reboot.
Now you should be able to go on with the rest of the guide, as if you physically unplugged the harddrive(s) inside your rig.
When done with a completely working install, just boot into BIOS and enable extra harddrive(s)
END OF EDITED INFO
Disconnect any and all PATA(IDE) drives connected.
Make sure only your GPU are installed in your rig - everything else might be incompatible - connect upon succes in installing SL.
Also only connect mouse, keyboard, 1 display, max 4 Gb memory, and LAN cable.
I use USB - PS/2 might work - if not, use USB.
3: Boot XP disc (or any other boot disc that can partition your HDD) and remove all partitions, or you will receive
EBIOS ERROR 0x09 errors.
If your drive is already unpartitioned (no partitions) skip this step.
4: boot into BIOS and set the following settings:
a) load Optimized Defaults
b) set SATA as AHCI
c) MAX CPU VALUE LIMIT: Disabled
d) ACPI2: Enabled
e) Suspend mode: S3 only
f) Change the boot priority to have your intended OSX hard drive as first to boot.
g) Insert iBoot into optical drive.
h) Exit and Save BIOS settings - very important
5: During POST, when your USB controllers has been enabled (my keyboard has blue backlight - it powers on when enabled)
press F8 and choose to boot from optical drive.
6) When iBoot Chimera menu appears eject iBoot disc, and replace with Snow Leopard 10.6.3 retail disc and press F5.
7) Select your Snow Leopard retail disc and type PCIRootUID=1 and press ENTER
8) When Snow Leopard installation pops up on-screen choose language and then open Disk Utilities, and choose to partition
your HDD with 1 partition only - use MAC Extende (Journaled), then press Option and make sure you are using GUID.
Click Apply and then exit Disk Utility.
If you need more partitions for data storage, you can always repartition once SL runs smooth.
8) Now click next and choose your (only) drive to install to, and click Customise.
Deselect everything - you can install it later - this makes the install go faster.
9)Click continue - then Agree, and watch the installation take place. Remember to move your mouse a bit every 40 seconds
or so to prevent sleep - or your install will fail.
It should take around 20 minutes - mine took 17, but I guess it depends on optical drive speed, memory and such (or I might be wrong about that).
When successfully installed hit Restart.
10) When your rig has restarted and are showing POST hit F8, and replace Snow Leopard retail disc with iBoot again.
Choose to boot from optical drive.
11) When Chimera menu appears, select your Snow Leopard installation, and remember to type PCIRootUID=1 and press Enter.
12) Open MultiBeast but do not go through with patching yet.
13) Mount and install Combo Update 10.6.8 - when done it will ask you to restart but do not restart yet. Instead go
back to MultiBeast - if MultiBeast has closed, open it again.
14) In MultiBeast choose:
EasyBeast Install
a)Drivers & Bootloaders-->Kexts & Enablers-->Graphics-->ATI 48xx Patch for 10.6.8
b)Driver & Bootloaders-->Kexts & Enabler-->Graphics-->ATI 48xx Inject
c)Drivers & Bootloaders-->Miscellaneous-->FakeSMC
d)Customization-->Boot Options-->PCI Root ID Fix
e)OSx86 Software-->Kext Helper
f)OSx86 Software-->Kext Utility
15)Look in Application folder and open Kext Utility - it requires you to type in your password - do so. It starts repairing
permissions and caches. Once you've run this you're ready to restart. Go ahead and do so - remember to remove iBoot
from your optical drive.
Let your rig boot without any interruption from you - it should boot just fine now.
When your rig has done booting, and shows your desktop you'll notice sound and LAN are not installed - no devices are
present. For this we need the 2 kexts I link to in this guide - see bottom links.
16) Open Kext Help b7 in Application Folder. Drag both kexts into Kext Helper b7 and type in your password, and then
press Easy Install.
17) Open Kext Utility again, and once again let it fix your permissions and caches, and by now, without even restarting,
both your LAN and sound are working - if LAN are not showing cable plugged in, give it a minute or two - it'll register
App Store log-in issue
18) Download EFI Studio - download from here http://www.osx86.net/view/91-efi_studio.html
Run EFIStudio 1.1, and then on the first drop down list, select 'Ethernet'. Click 'Add Device' and there
should be a new window that pops up with something like this on the bottom - this is your
EFI string for your LAN:
4b00000001000000010000003f0000000100000002010c00d041030a0100000001010600051c0101060000007fff0400160000006200750069006c0074002d0069006e0000000500000001
Open your com.apple.Boot.plist in your Extra folder (if you are using the latest boot loader, there is no com.apple.boot.plist
in /Extra, you will need to add the string to /Extra/org.chameleon.Boot.plist) with Text edit and add this EFI code to the plist:
<key>device-properties</key>
<string> EFI-string-from-EFI Studio-here </string>
Congratulations - you're now running a nearly not patched, fully legal, fully updatable
OS X Snow Leopard CustoMac !!!
Have fun - and remember, buy Snow Leopard !
Onwards to Lion
Simply put, follow the official Unibeast guide via the link below

1
I did it this way, since I wanted to run both Snow Leopard, Lion, as well as Windows 7, that I started by partitioning
my OS X harddrive in 2 partitions; one for Snow Leopard, and one for Lion.
2
Rebooted into BIOS, and disabled my Windows 7 harddrive - remember to save settings before rebooting
3
Boot back into OS X Snow Leopard
4
Follow the official Unibeast guide - I installed to my pre-partitioned Lion partition
5
When done installing Lion, updating Lion with latest updates, and you've run MultiBeast, and
are able to boot into both Lion and Snow Leopard (if multibooting):
boot into BIOS and enable your Windows 7 harddrive - remember to save settings before rebooting
And voilá - you're now running multiboot SL - Lion - Windows 7
Mandatory kexts for sound and LAN
