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...
1. every time, when the system execute failover.c and it will read cmos to decide it will continue with fallback image or jump to normal. 2. a. did you put atix.rom in you rom? atix.rom is about 48KiB. b. In your MB Config.lb, you need to make sure your device num is right. Otherwise it can not get 0xfff8000.
