Yes - the only weird thing is that the boot code lives at the top of the
address space. You will also need to know a fair amount about your
motherboard chipset to replace the boot-time configuration of the BIOS as
well. For custom boards this isn't much of a problem, you know what
devices are there and you know how you want them configured. For commodity
motherboards, I would be wary of doing this - chipsets have a rather short
life cycle here so the board you designed your boot code for may not be
available in 3 months..
