No, its not a good idea to write a protected-mode bootsector. Because
you need
some tables and checks before you enter protected-mode. And you loose
bytes
(theres only 499 of them), for procedures you need to load a sector
(8GB-LBA)
and service function.

The better way is like NT, i think its a 2-stage-loader:
Make a bootsector, load a startup-image - that supports
a filesystems, and this programm loads our kernel-image.
