That's the active flag.  It has no defined meaning, at least not in any
meaningful sense:  It's just a flag.  The unnamed Microsoft MBR program
heeds it, branching to the first primary partition that bears that flag.
I know of no other boot utilities that pay any attention to it at all.

OS/2 doesn't (if fading recollection suffices).

Microsoft OSes do, but only when you run their installers.  But that's
when you pull out your boot floppy, boot it, and re-write the MBR the
way you prefer it.
