Hi,
I am using the open source drivers , radeon and radeonhd. When I try it on a similar board with AMI bios , xrandr can switch on the HDMI port without any problems - with radeon and radeonhd. I guess I could give Catalyst a try to see if it makes any difference(maybe it does magic with the vga bios) I think however, that the problem lies in the fact that some config needs to be done in PCIE-GFX , so that one of the ports gets configured as TMDS. Right now, I am trying to get that to work - so far no results yet .... Another interesting fact is that I am working with this board that does not have another BIOS except for coreboot .... so I have nothing to compare register values with.
Greetings,

Daniel, I'm sorry I don't know the answer to your issue.. But I have a question? Are you using the open source driver or Catalyst? Have you tried Catalyst and does it run?
Thanks Dan Lykowski

Dear All,
I am working on supporting yet another AMD 690E based board. We have everything working fine, except for the HDMI output. I can't seem to switch to an HDMI or DVI monitor with Xrandr. The RS690 Register programming requirements , page 65 (PCIE inititialization for TMDS) starts explaining the steps to get TMDS working - as far as I can see they are not implemented yet in southbridge/amd/rs690 ? Implemening those steps would bring up HDMI or are there other things that need to be taken care of ? The VBIOS binary is given to me by AMD and has HDMI support, so they say. The ASIC revisision of the chip is A12. Any comments / idea's are more than welcome.
Greetings,
Daniel Toussaint
