Hello guys,

I've problem with my card which is ATI Mobility Radeon HD 4300/4500 series. [1002:9555].

I've installed OSX 10.7 and everything works fine except graphic. I found thread about enable QE/CI in Mobility Radeon but I can't understand how to begin. Can someone guide me which first should I do.

So far what I've done -

Set my device id in ATI4600Controller.kext and ATIRadeonX2000.kext - Blank screen after reboot

Use ATY_init - quitting 9555 message in boot.

Get Bios rom using dong tools but I don't know how to decode using bcc9 radeon_bios_decode. I type ./radeon_bios_decode <rom file> controllers.txt but it just stuck without response.

Also I don't know which family my card is, maybe shrike or megalodon. How can I find it?

My System -
Compaq Presario CQ42-268TX
Intel i3 350M 2.27Ghz
ATI Mobility Radeon HD 4300/4500 series [1002:9555]

Here I attached my card bios dump

Thank you very much
