So did version 1. It used the same idea as /RAM on a 128KB machine, drop
the root directory from 4 blocks to 1 (limit of 12 files). In the most recent
versions of P8 and BASIC.SYSTEM this is completely supported - the root
directory can either be 1 or 4 blocks (and no other length).

block	0	boot block
block	1	?
block	2	directory
block	3	bitmap
block	4...	data
