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.
