Always set the magic sequence when we write, rather than trusting the previously read boot code to do so. Use explicit encoding/decoding of little endian disk image. Remove a comment which was OBE. Change the test vector for "fdisk -I" to reflect that there is a magic sequence in the result now. Add test case for "fdisk" which reads the image back. At least for the two test-cases this program now gives the same result on sparc64 as on i386. The lack of an installed /boot/mbr on sparc64 raises an (un)interesting question.
