Hi, I want to implement a Callback Function (04E08H- System BIOS INT 15H) for the AMD Video vBIOS (ATOM BIOS Extension Functions) to support LVDS TFT Displays with AMD G-Series processors (Persimmon mainboard). What is the best way to do this in SeaBIOS? I need some parameter like UMA base and size from Coreboot. How can I transfer this information from Coreboot to SeaBIOS? Thanks, Wolfgang
