I used coreboot with SeaBIOS and AMD's vBIOS. System booted successfully except display not turned on.
I used DirectTMDS for primay display. BIOS had been red my display's EDID rom. I had seen this signals with an oscilloscope.
Error ocurred on executing VGA BIOS code. How do I turn on display?
Here is log message.

Hi,
I'm not sure if you've already resolved the problem you were having.

You probably want to name the rom as "pci1002,791f.rom" instead of "vgaroms/radeon.rom" - when the rom is named with the PCI id, the pci id is passed into the rom at startup, and the rom may require this.
Also, how did you acquire the rom?
