Re: Flashing too big??

Aha ... that clears up lots of questions.

But it raises one, too ... So my bootstrap is apparently getting loaded 
into banks 47 and 48. Fine. And that apparently leaves banks 49-4F unused.

How does the low level TINI bootstrap know that it should be loading banks 
47 *and* 48 instead of just 47 ... or 47-4F? Is there a descriptor record 
somewhere that says how much to load? (I assume that the descriptor would 
contain a byte count, not a bank count, and that however many bytes are 
actually valid is however many bytes it actually loads.)

... just tying up loose ends ... not planning any weird tricks.
