hi there, thanks before all things for your next help.

 

actually, IPC 10.5.6 woking fine on my computer but I'm using an old ati card (x550) with natit. so I have no QE/CI/OpenGL ..etc

I am trying to make a new install with a powercolor radeon HD3580 pcie card without success.

after many different installation (with natit or ipc 3850 driver) impossible to boot after installation ( freeze colored mozaik screen or grey apple stop panel).

 

can I get help ?

thanks

I would try to get it to run using EFISTUDIO_EXTENDED (serach for that here, also DL link).

You can make your own efi gfx string easy by selecting your gpu type.

I recommend using seltetion ATI3850_MEGADOLON ( i made that extra selection) which works better than the normal one (also Natit often uses LAMNA Framebuffer - no way for my 3850)

Be sure to remove any gpu injectors like natit or nvcrush if you using an efi gfx string !

Also you need unpatched (orig.) Apple ATI drivers >= 10.5.5 .

The Megadlon FB is within ATIRNDRV.kext - check that if you have it within that .kext.

can you please include a link to the EFISTUDIO_EXTENDED post. I searched for it, and also browsed the posting titles, but couldn't find it.

Btw, my Radeon HD 3850 dual monitor setup is working because of the Natit.kext that you provided, that injects MEGADOLON. If i can get the same thing with an EFI string, that would be nice. Also, maybe that'll fix some other minor issues...

 

Thanks :blink:
