My next step will be to get some graphics out of this box. On the board is an onboard graphics chip and according to the specs it is VGA compatible. I am using the serial-console for debugging and for sending characters to the box. My source tree is based on kernel 2.2.12. Because the chip is VGA compatible I try to get the VGA16 framebuffer running on the box. After enabling the VGA16 framebuffer I receive the following output: Jumping to image at 800605DCh...
