That's always possible (and no relevant test for the above question) as
PC's use two different methods to boot from CD's, and don't need sector 0
for that _ON A CD_.
hp700 LIF uses 0-1 and 240-251?
240-251 might collide with the NetBSD disklabel in the SUN label sector,
which is at 128 ... 419. The SUN label information is beyond that
(420 ... 511).
