Dear all , I have some questions , hope you can give me some idea 1.What is the difference between normal booting and fallback booting? When linuxbios will use normal booting and when linuxbios will use fallback booting? I remember I use the hdama code , and it always use fallback booting, and now my new porting it always use normal booting.
2.VGA problem, I tried to add VGA, I have succeeded before when I use hdama code , now I follow the same way , but I got a message "Incorrect Expansion Rom Header Signature ffff ", I trace the code and found the rom_address become fc000000, not the fff80000 we have set, could anyone tell me what mistakes I made?Does it related to my question 1?
Thanks...
