Hello to all the forum guys ... I need mega help and I hope we can together to help ke anke ke all those like me, have the same problem ...

X place you start the PC in question ...

RAM: 4GB DDR3 1333

VIDEO CARD: SAPPHIRE ATI HD 4850 1GB-VGA-DVI-HDMI

HD: WD 300 GB SATA

Burner: LG SATA DVD-DL

MONITOR: PHILIPS 19 "1280X1024 MAX RESOLUTION DVI-VGA

 

Then I tried to install several versions but the PC will go wrong xke get it back .. so I went into the store and I bought both the snowleopard ke .. but the snow leopard is installed only with the-x command only starts with the command -x-v ... and then definitely will sceda a problem with the video .. I tried both the 10.6.2 combo and the leadership of your wiki result but black screen "stanbay" or the screen with so many colors around ... installing the 10.6.4 combo I had black screen, screen colors and scattered black screen that says sleepmode .. I was more than 5 days to try and beat drivers from various forums but nada ... nothing to do .. sad.gif

k and then I noticed the problem on the leopard video card was resolved .. ke not only makes me install .. I'm really desperate because ke PC in question has just been assembled with all new parts sad.gif kiedo so kindly if a guide or something I can fix my problem ...

*I still need to plug in an DVI->VGA adapter on the unused DVI port. Try this if you get a black screen instead of proper graphics.

 

**This problem of dvi2vga dongle was due to a change in the framebuffer version 10.6.3 +.

no need to use the dongle dvi2vga, just use the 10.6.2 kexts (ATI4800Controller, ATISupport, ATIFramebuffer).

that was the problem that was fixed in 10.6.5

ziospliff you can try the attached files that I have in my post just install the kexts first using kext helper

 

reboot into safe mode (-x at darwin prompt)

 

then use kext helper to install the evoenabler.kext and install the exotic 10.6.2 package

 

it gave me full resolution and QE/CI working in all versions of 10.6. (I'm currently on 10.6.4)

 

The only downside is that I only have the dvi port working neither vga nor hdmi gives me any output not sure why.

 

I still can't find the 10.6.5 beta from my apple dev account not sure why but madld0n confirms that it fixes the 4850 issue without having to install any kexts but this most works for the 4850 cards with dual DVI's and the s video tv out. It differs from the cards that we have which only have 1 dvi.

 

Good luck though.

nothing ... I tried your procedure and the result is always the same .. I reveals a ati hd 4830 256mb black screen or a confused .. then 10.6.5 upgrade but I found a kernel panic from me .. I guess I have to give up .. : (

He means the original kexts that came when you first installed the 10.6 system

 

Basically the phones you never modified to put in dev id's and such. It bothers me that your 4850 isn't working with all these methods... This version seems odd as the other makers like GIGABYTE and Sapphire 4850's seem to work fine one way or another.

thanks guys for your help .. how did you notice on this computer only works the retail version .. now I tried to reinstall everything .. tried to install the various combo "10.6.2-10.6.3-10.6.4" in multibeat userdsdt and I put my dsdt added to the desktop without installing any driver, and always starts with the "-x" the only thing not tried is putting in some dev id kexts since I do not know how to do .. I have tried everything else ... I commend you ... you are great!!

no problem Zio

 

So you can boot into safe mode right and it still displays the 256 mb for the vram for your card?

 

If you want, you can msg me on msn or gtalk I could help you out with it over the weekend since I'm not doing much this weekend.
