help with ati 4850 and SL 10.6.3

[zuzudom]

I did everything written in the blog but as soon as I try to rebboot after patching the system with any immaginable kext for my vga i got black screen but I hear the sound of the system opening so I guess everything works except vga,even with -x,after patching the screen goes black.

I tried even netkas tips but for nothing.......my HW is in sign.PLZ HELPPPPPPPPP

Hy Tony and guys,

i have the same issues on my PC :

ASUS P7p55D LE
ATI 4850 1go ( saphire )
2 GO memory
500go samsung


Success install from ati boot cd new version ( with full graphics ON )
Update 10,6,3
Done Multibeast easyway

BUT whatever i choose for my graphic card, i will always get a blank screen.
only thing i can do is get control from my laptop and delete the kext in libreay/extension in order to have a screen back but in an ugly resolution and of course, with no support of my graphic card.

What can i ( or we ) do for that tony ?
Thanks very much for your help !

Steven

I had a working 10.6.2 system but after updating to 10.6.3 I have the exact same black screen problem. The system seems to be working but no display. even -x safe mode is same black screen.

Can anyone help fix this without me having to reinstall everything to go back to 10.6.2?

I believe you need to retain/use a couple of the old 10.6.2 kexts, when on 10.6.3.
