VisonTek 4890

[Vanillian]

Documentation on the 4890 is surprising sparse and confusing. I have the VisonTek 4890 which I purchase because it has 2 DVI ports and no factory overclock which should make it a reference model.

 

Here is where I currently stand:

OSX 10.6.2

PC EFI 10.5

 

In System/Library/Extensions:

 

ATIx2000.kext

ATI4800Controller.kext

EVOenabler.kext

 

Both ATI ktexts have been updated and contain the 4890 0x94601002 ID.

 

I have installed them using Netkas' 10.6.2 QE Exotic Patch, and installed EVO using Ktext Helper B7.

 

Should they also be placed in /extra/extensions?

 

I repaired permissions.

 

In com.apple.boot.plist I have graphics enabled.

Here is my error message

 

 

The messages show are:

 

kxld[com.apple.kext.ATI4800Controller]: The vtable (Gives numbers/letters is corrupted/damaged) please check against the correct headers.

 

Can't load kext com.apple.kext.ATI4800Controller

 

Failed to load executable for kext com.apple.kext.4800Controller

 

etc, etc basically the same message repeated for 3-4 lines.

 

When I finally do get to OSX the screen is all garbled, a mix of white and black streaks and boxes.

 

Any help would appreciated.
