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.
Desktop de 25 de mil
Hello,
Saptamana trecuta mi s-a stricat desktopul, asa ca a trebuit sa il inlocuiesc, am reusit cu un buget redus sa imi contruiesc o masina super decenta, pentru curiosi in windows 7 x64 ultimate am
- 6.9 cpu
- 5.9 ram
- 7.2 aero graphics
- 7.2 gaming
Hdd-ul inca nu l-am upgradat inca mai functioneaza ala vechi si din pacate fiind doar SATA e destul de lent, mai putin conteaza hdd-ul poate 10 sec in plus cand se incarca windows sau 10 sec in plus cand pornesc vre-un joc sau o aplicatie mai pretentioasa.
Sa trec la lucruri serioase configuratia e un i3 530, gigabyte p55, ati 5750, DDR3 1333,sursa 650w de la emag toate ajung 21 de mil, in detaliu:
| 1x | Sursa Rasurbo GaminX&Power GAP-656 V2, 650W | 279,00 RON |
| 1x | Kit Dual Channel Kingston 4GB (2 x 2048 MB), DDR3, 1333MHz, ValueRam | 399,00 RON |
| 1x | Procesor Intel CoreTM i3 530 2.93GHz, socket 1156 | 479,00 RON |
| 1x | Placa de baza Gigabyte P55-US3L, socket 1156 | 399,11 RON |
| 1x | Placa video Sapphire ATI Radeon HD 5750, 1024MB, DDR5, 128bit, PCI-E | 544,98 RON |
Total 2100 RON, nu mai trebuie sa adaug, emag ca de obicei a livrat la timp si fara complicatii.
Procesoru merge in 3.3 GHz de cand l-am instalat, l-am oc cu soft-ul din dotare fara nici o problema, cred ca poate fi dus lejer in 3.6-3.8 GHz, pentru placa video am folosit un programel MSI Afterburner si fara nici o problema am dus placa video de la 700 la 800 MHz GPU iar memoria de la 1150 la 1300MHz.
Sursa desi "no name" la prima vedere e facuta de o companie germana si exista ceva review-uri online, duce fara probleme sistemul si e foarte silentioasa, are toate cablurile necesare si e destul de ergonomica.
Placa de baza destul de saracuta dar eu sunt multumit , e micro ATX incape lejer in orice carcasa iar overclock-ul e la un click distanta cu soft-ul pe care il ofera Gigabyte, desi suporta CrossFire si CrossFireX al doilea PCIE merge la 4x deci mai bine nu.
3dMark Vantage a scos un scor de 10100 puncte cu procesorul si placa vide oc si 9400 fara oc.
Desi overclock-ate componentele la valorile de mai sus, temperaturile raman jos sub 50 de grade CPU, iar GPU 60, cooler-ele kit pentru procesor si placa video sunt foarte silentioase, practic desktopul e la fel de silentios si rece ca un laptop, mai harie hdd din cand in cand dar cam atat.
Configuratia ar trebui sa fie ideala pentru fanii Hackintosh 
atat placa de baza si procesorul sunt suportate de kernel-ul vanilla .
Concluzie: cu 2100 RON iti iei componentele de mai sus ca sa iti faci un computer complet mai cheltui vreo 300RON pe un HDD SATA 2 si vreo 100 de RON pe o carcasa, si cu putini bani bati la fund un laptop Alienware la orice ora in materie de jocuri, nu mai zic ca Alienware trece de 5000 de RON usor, nu stiu ce gandesc baietii astia de la DELL de baga preturile asa mari la laptopurile alea.
