Hi,all
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?
Best regards!

There _is_ flash on a "standard" PC, that is what holds the BIOS and is equivalent (loosely speaking) to u-boot. Replacing it with u-boot is theoretically possible, but would be difficult. The existing BIOS on your MB supports the hardware on the MB. To replace it with u-boot, you would need to figure out all the details of your MB hardware (often impossible) and port u-boot to support that hardware. If you are wrong, you will "brick" your MB.
There are open BIOS projects that would probably be a better starting point. http://www.linuxdevices.com/news/NS2401026948.html
