[U-Boot-Users] Can u-boot work for PC?

[OneWinged]

 
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.

Most boards do have flashon board. They use it to store the BIOS.

Usually that's not ROM, but flash.

If you accept that "some fix" is a  big,  non-trivial  project  which
requires  an  intimate  knowledge  of your mainboard and it's chipset
(including access to related developer's documentation which  is  not
easy to find), then the answer is yes.
