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).
