Yep - *OPT 4 sets a flag on the disk indicating whether to use !boot and 
what to do to it:

*opt 4 0 : Ignore !BOOT (default)
*opt 4 1 : *LOAD !BOOT
*opt 4 2 : *RUN !BOOT
*opt 4 3 : *EXEC !BOOT (probably the most useful).

Just as a matter of interest, has anyone come across a *opt4 1'd disk? I 
don't recall ever having seen one, or thinking of a situation where it 
might be useful.

Cheers,

Frank
