Oy. That's not what I meant to say -- let me try again. 

In both cases (RAM startup and ROMRAM startup), RedBoot is
running from RAM at the same location.  There is, AFAICT, no
significant difference in the executable image.  In one case,
you're allowed to configure RedBoot as a monitor. In the other,
you're not.

I don't see why there's a difference.

Or perhaps more importantly, why does it object to it only part
of the time?
