I have a intel/Truxtion board and would like to try the coreboot on it.<BR>
By now, I have successfully built the coreboot for Truxtion with filo payload.<BR>
without VGA, it can work through the serial port.<BR>
However, when I used the add-on VGA card, it firstly hang in the VGA Option ROM.<BR>
After hard debug( the emulator debug is really hard for me, since I can't directly track the OptionROM code I running now), I found the issue.<BR>
The OptionROM will check the System Mode Flag(0xffffe), if it is not the 0xfc, it will hang.<BR>
However, the coreboot doesn't touch the 0xffffe address. May it is a bug of coreboot.<BR>
after fix this issue, the screen can be turn on, but unfortunately, the screen is chaotic. I changed another add-on card and got the same result.<BR>
Any idea on it?<BR>
by the way, the add-on VGA card I used is Matorx G550.<BR>
