[SeaBIOS] VGA Callback function in SeaBIOS

Tue Nov 22 17:39:07 CET 2011

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
