I've been thinking this question for long time.There's only one supported board of x86 arch. But it's different with PC. There's no flash on PC's board, so where should u-boot be stored? I think it may be hdd, correct? And PC have rom-bios. I'm trying to make u-boot work for PC and find it so difficult.Is there anybody has done this work? Can the source for sc520 board be used on PC with some fix?
