A few shots in the dark, maybe they help. Is it possible that the failure reason is totally unrelated to graphics? Maybe the ATI driver uses a timer which is set up differently under coreboot? Or it is waiting for an hardcoded interrupt or some ACPI event which only exists in the reference BIOS? Side note: RS690 ACPI PCI config space accesses were broken in coreboot because they assumed MMCONF and MMCONF was disabled before starting the payload last time I checked. Maybe your issue is related? Regards, Carl-Daniel -- http://www.hailfinger.org/ -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
