The issue is that the firmware will loop around to zero after it reaches the
maximum size addressable by the
6-byte commands. Anything needed for booting needs to be under the limit or
VMB can't get at it.
In addition dumps done by the firmware that extend past the boundary will loop
back to block 0

 Yep, boot drive only.
