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. gvb
