I think it applies to almost all boot firmware -- the Atari 68000 hard
disk format used it, all the x86 firmware I am familiar with uses it, and
I think Apple uses it in all it's Mac incarnations. That's pretty wide
coverage (I know nothing about Sun or other workstation formats).

If the 0xAA55 marker is not present, the standard interpretation is that
the disk is not partitioned, and the disk may still boot, but you may
just be lucky it works if it really is partitioned.

Or have I missed something (I'm not all that familiar with non-x86 hardware
so I could be missing something big -- and I'd like to know that)?
