Chameleon is trying to load Duckweeed frame buffer acording to bdmesg:

Using PCI-Root-UID value: 0

I have GE=yes in my boot.plist also tried many combinations of chimera and chameleon , AtiConfig, Atiports etc..

I have added this code into my ati.c

	{ 0x6738,   0x03b01043, CHIP_FAMILY_BARTS,	  "AMD Radeon HD 6870",			kDuckweed   },

And this is the result all the time:

+-o ATY,ATY,RadeonFramebuffer@1  <class AtiFbStub, id 0x1000002fd, registered, matched, active, busy 0 (3

Anyone having same issue?

Thx for help

I have framebuffer duckwed loaded

but it's no good for me, I have Power Color eyefinity 6870 with 6 mini display port and the best personalities is Bulrushes with 6 display connector but no succeed to boot with , i try with aticonfig but the same duckweed loaded.

@plesuvescu: Probably you have duckweed hardcoded in your booter?

@plesuvescu: Probably you have duckweed hardcoded in your booter?

 

Using AtiConfig=Bulrushes would override whatever personality is configured in the bootloader so that shouldn't be an issue.

Marek did you get the third port to work ? I've tried Duckweed or Bulrushes but the HDMI port does not work.

[Alexander Martinez]

@Marek: Do you have pci-root set in your org.chameleon.boot.plist? I recall reading that this may cause the bootloader to not load personalities correctly. Also, try to update to the latest chameleon (or chimera) if you haven't done so yet.

 

@baguazao I just posted a guide that could help you out with that, and there is a post from mcbyte_it that makes it even easier to create custom connector descriptors (I wish I had seen it earlier!)
