[markoboy26]

Hi guys,

please help!
i have installed SL 10.6.3 and i've got a problem for my video card. i do not installed my hd 4650 card.
if i use the kexthelper b0.7 the SL is DEAD. Kernel panic promptly!!!
I dont know what is the problem.
my os...
snow Leopard 10.6.3 (HOTiSO)
my card:
ATI Radeon HD4650
ID's:
9498
1002
Memory: 512MB

I use the Magic CD, Chamelon RC4 with CD, i boot from these every starting.
I replace the modified X2000 and X4600 kext WITHOUT kexthelper, and i use the disk utility and the repair permission functions, so i don't get kernel panic, but my resolution is ONLY 1152*864 and I not modified, but ive got an error, look this:
"System extension cannot be used
The system extension "/System/Library/Extensions/ATI4600Controller.kext" was installed improperly and cannot be used. Please try reinstall it, or contact the product's vendor for an update."

I get this error message from the X2000kext too... restart, but the resolution is bad: 1152*864 without QE/CI..

My monitor resolution is (DVI input) LG widescreen 1440*900.
The QE/CI does not work!!! And i don't know what is the solution
I try many (4-5) possibility, but none work
Please help me, what is the correct solution!

MB: Abit IP-35E, DDR: DDRII 800MHz Kingston 2x1GB, HDD: 160GB SATAII Seagate, VGA: ATI RADEON Sapphire HD4650 512MB GDDR3.
