Asus Radeon HD 5450 Silent and Mountain Lion w/ Dual Monitors?

[leodoct]

Dear AppleMacIdiot

Thanks again for your effort. We had a progress modifying my dsdt.aml. Now i can have full function dual display (extended, mirror, recognised, etc.) only and only if i boot with one monitor plugged and after boot i plug in the second. When i boot with the two monitors plugged in my graphics card is confused and have the same behaviour (the two screens are configured as secondary). Any way i can live with it, it is a serious progress. I attach below my last configuration. If you have any free time, have a look for mistakes in code. One last favour. I would like to recommend me references, books, notes, websites, etc. to begin studying about how UNIX and especially OS X works because i am seriously interested about, but also confused with such volume of information.
Thanks again.

Thanks to AppleMacIdiot - the info in this thread has really helped get things working. It would have been a long hard road without your help.

The h/w

z68ap-d3 UEFI bios revision Ua5
core i5 2400
Asus HD5450 1gb silent (sorry - I forget which exact model, but check the dump of my Rom if you want to be sure that you have the same) - DVI, hdmi, vga outputs
Dual screen, DVI and VGA work. HDMI to be tested next week, no HDMI audio will be attempted
Multibeast 5.2 install, and no DSDT used. System model selected is MacPro3,1 (default)
OSX 10.8.2

The Kext's are attached, and patched as follows :

1. Patched the Info.plist on the following kexts... (thanks to the thread starter for the link)
AMDRadeonAccelerator.kext
AppleGraphicsPowerManagement.kext
ATI5000Controller.kext

2. And hexedit patched ATI5000Controller.kext using AppleMacIdiots 11 step guide (post 47) using the hex values supplied there

PS. TIP if you do not have windows installed you can dump the gpu bios using the clover bootloader. Just install it to a MBR partition, Msdos formatted USB drive. And press F6 to dump a bios to the USB key.

Hi abzurdistan,

Here's your patched ATI5000Controller.kext file for your Sapphire HD5450
Included is a, RTF text file with the dumps from your card's BIOS rom and the edits for the Eulemur personality are at the bottom incase you need to patch your own kext again after any updates to OS X and such.

Sorry about the delay on this, it has been a pretty rough week.

Good luck and please let me know if this helps...

Ciao!

Hi AppleMacIdiot,

Sorry for the really late response, but there was too much work to do...
Used your .kext and voilá! anything works smooth execpt that the Card isn't recognized as a HD5450 but as a HD5400.

Thanks a lot!

I can confirm that method #2 (as indicated in the link post) works with a Sapphire HD5450 512MB. I couldn't get method #1 to work. I didn't try method #3.

Thanks to everyone- I figured out myself from the above post and got my card working perfectly with lofie's kexts.
Your efforts are greatly appreciated. Thank you very much!
