Installing ATI 5750 with Snow Leopard
Hey dude, this is a follow up for my latest post regarding installing the beloved Snow Leopard on a PC, so if you did't read the first part you can do it here, is mandatory.
Ok for those that already read the first post you remember GPU-Z and the dump of your video card rom somewhere where you can access it later, look for it because you will need it soon.
Now go to here and get these drivers from netkas.org, open the archive and you will see a bunch of kexts and stuff over there, right click ATI5000Controller.kext, click "Show Package Contents" go inside and edit Info.plist.
Where you see <string>0x68981002 0x68991002 0x68E01002 0x68E11002 0x68D81002 0x68C01002 0x68C11002 0x68D91002 0x68B81002 0x68B01002 0x68B11002 0x68A01002 0x68A11002 </string> add your device id you should have that from GPU-Z if you forgot to take it just open System Profiler(you can find it in Utilities), there you should see the device id and the vendor id my dev id is 0x68BE and vendor id is 0x1002 so what i added in the kext plist above was 0x68BE1002.
If you have another ATI 57xx your device id might be there already if not just add it while you are there edit Info.plist from ATIRadeonX3000.kext, add your dev id there as well in the same way we just did for first kext.Ok you are done with the dirty stuff, open KextHelper, you installed with MultiBeast drag next kexts:
- ATI5000Controller.kext
- ATIFramebuffer.kext
- ATISupport.kext
put your password click Easy install and restart, if no kernel panics so far add ATIRadeonX3000* stuff in kext helper, install them
Then take your rom the one you got from GPU-Z name it like this: 1002_68be.rom if you have the same dev id like me if not instead of 68be put your device id in the name copy it in the Extra folder in the root of your Mac OS partition,
Now edit /Extra/com.apple.Boot.plist
drag it on you desktop and make sure it looks like this:
- you installed the rest of the kexts
- you renamed you rom video and you copied it into /Extra folder
- you added the flags in com.apple.Boot.plist
restart your computer, everything should be fine, be sure that before restarting you have only one monitor plugged, after you successfully restarted you should actually have a fully installed ATI 57x00 card, plug in the other monitor, detect monitors and you should have the extended desktop on the other monitor, as well as QE/CI working. 
you can see here my both monitors working at full resolution.
Here is my XBench test
http://db.xbench.com/merge.xhtml?doc2=475246
ok so what we got is a full working mac with some decent benchmarks, the hdd I used to install Leopard on is pretty old so not that fast this is mainly the reason for a poor benchmark score, you can get lot better with a fast hdd and a better CPU.
what we didn't get 
, each time you restart you need to unplug one of the monitors and plug again after your SO started, also i have some issues with USB you can fix some of them following this tutorial, I did install myself but I still have some issues, also sleep doesn't work , it sleeps but never wake up, the thing is that I do not need sleep , if you need it there are plenty of resources around to fix it, it shouldn't be that hard, but always remember to backup your system before making any modifications to your installation(i use disk utility to create an image of my Leopard installation) and when i will need it will just restore it and install a boot loader and have it as new.
Hope this helped someone, until I got it right I spent lot of my free time if I can save you some of this time then this post fulfilled its purpose.
Installing Snow Leopard
Hey,
Some of us do not want to spend lots of money on Macs they are pretty expensive about twice the price for a PC, but what do you do if you really want the Apple SO Mac OS X on your machine, well not that hard, you can buy the retail version of the Mac OS X(much cheaper than Windows btw) and follow this tutorial here, this should work for most of you.
However I didn't use that to install Snow Leopard on my machine so in the next posts I will describe what I did to have it installed, the steps should help any of you with the same configuration to make your Hackintosh in the same way I did.
So let's start:
First I checked my configuration, see exactly what hardware I bought, this is it:
- Intel i3-530
- Gigabyte P55-US3L (the revision with P55 chipset not H55) , I updated to latest BIOS version FH,using the windows utility that came with the motherboard, worked like a charm
- Sapphire Ati Radeon 5750 1GB for the video card
- 2 SATA HDD(1 has a win 7 x64 installed)
- DVD-RW
- 8GB USB Stick
- 2 displays(1280x1024,1920x1080)
- 4G RAM
What software I needed:
- ImgBurn - http://www.imgburn.com
- uTorrent - http://www.utorrent.com
- GPU-Z - http://www.google.com
- iAtkos s3 v2 - http://www.google.com
- MultiBeast - http://tonymacx86.blogspot.com/2010/02/multibeast-ultimate-post-installation.html(do not download in Windows, you will download inside Mac OS once is installed)
So far ensure you have same hardware or close to it, any P55 would work pretty much the same, any other i3,i5,i7 should do it as well, and for the video any 57xx should work also, if you have an NVIDIA card this tutorial is not for you however everything should work fine beside the drivers installation for your video card, you will need to find other guides to install your Nvidia.
- Now after downloading the iAtkos distro burn it using ImgBurn at slower speed I did it at 4x and was ok.
- Next open GPU-Z utility and write down the details of your video card like DeviceId and VendorId, you will need it later, but the main purpose of GPU-Z is to save your video card BIOS, so do it and save it somewhere on the disk and remember the path, use the hdd where you want to install Mac OS but not same partition since that is going to be formatted.
- Next you need to prepare the disk where you want to install Mac OS i suggest you use a separate HDD, like I did, I formatted a partition with NTFS abt 50 gigs would do it name it SnowLeopard
- Next shutdown your computer and remove all the usb devices you have beside mouse and keyboard(btw a ps2 keyboard works fine as well, a mouse on ps2 instead of USB might cause problems, however I didn't test with this distro), if you are really newbie you should remove the windows hdd also to be sure you won't format it by mistake later
- Next restart your computer and enter BIOS, put your as your first boot device the CDROM, set your SATA mode to AHCI and set HPET to 64, save and restart.
Your computer now should boot from the DVD where you you burned the iAtkos iso, press F8 and you should see a boot screen with a list of volumes, first one and the one selected should be iAtkos, leave it like this and type:
-v cpus-1 busratio=22 (for other cpus see the list from here http://uphuck.ggrn.de/forum/viewtopic.php?f=62&t=13929 and set busratio accordingly for my i3-530 is 22 ) and press enter your system should start booting from DVD, you need lot of patience on my machine this step takes up to 10 minutes, and it freezes from time to time, nothing to worry about just wait, if you see a kernel panic you have a problem, but for me with my hardware configuration worked fine.
Next you should see a window appearing asking for language, I chooses English , never tested with the other options but it should be fine, click next button.
Now you should see a menu bar open Utilities, go to Disk Utility, here you can see on the left your volumes, click on the one you prepared for you Mac OS install should be listed as SnowLeopard, on the right click Erase, choose from the format combo Mac OS Extended (Journaled), you can keep the name SnowLeopard, click Erase, everything should go smooth, after is done (wait the progress bar that appeared), close Disk Utility, now press next, agree with the stuff they say there, read anything you find interesting.
Next step you should see your SnowLeopard partition click on it and the Customize button in the bottom left should be enabled, click on it, leave the defaults, and select next:
- Qoopz 10.3.0
- AHCI SATA
- Intel SATA/IDE
- JMicron SATA/IDE
- USB
- Uncheck Apple HDA
- Check also Realtek - only first checkbox from the list
DO NOT CHECK OR UNCHECK ANYTHING ELSE
Now install and wait for next 20-30 minutes the DVD installation is very slow, after is done it will restart, press DEL enter your bios and set as first boot device your HDD again, the one you used to install Mac OS, save, restart and press F8 again type -v cpus=1 busratio=22, your computer should boot and load Snow Leo just fine but you will have a default resolution and no sound, in the booting step you might see some errors like AppleUSBEAHCI.kext not found, which is fine you will take care of these later, no kernel panic happened to me until this step, and I did the above like 100 times until I got it perfect,everything was fine so far.
Once you set your timezone, your user, the registration with Apple is not mandatory btw, you should see Snow Leopard desktop, now is time to update your installation to 10.6.4, check all updates and install everything, reboot, everything should be fine.
Next open software updates again and install everything but the Graphics update( DO NOT INSTALL THAT), install the rest and reboot, next you will install MultiBeast, download it from the link above, your internet should work just fine in this step,
Install MultiBeast from the link provided above, check these options:
Install and restart, after restarting you should have sound, do not forget -v option when you start and in case your computer still doesn't boot correctly use also busratio=22 or whatever your cpu's busratio is, in case you get a kernel panic telling smth about VodooHDA you will have to start with -x and remove the VodooHDA.kext from /System/Library/Extensions using a terminal, the command is.
sudo -s
enter password here for the root user
rm -rf /System/Library/Extensions/VodooHDA.kext
then restart.
(In case you cannot boot with -x which is safe mode you will have to boot with -s which is single user and after you mount with mount -uw / execute rm -rf /System/Library/Extensions/VodooHDA.kext).
If you successfully restarted and booted in Mac OS you should have sound.
Now is late dude, see you in the next post I'm going to sleep next post I will tell you what to do to get Ati 57xx working with multi displays and QE/CI.
