Mike is correct.

Let me add that if the sparing sectors were moved to the end of the
'a' slice, it would have two effects:

a)	Restriction #2 above would change to "If bad144 bad-sector
	marking has been used (uncommon), the root FS and the few
	sectors following it must be below the 1024 cylinder mark".
	Essentially, this opens up a lot of space for BSD use on
	some drives (most notably those where you are likely to
	use the BAD144 in the first place).

b)	The bad sector area could be grown at the expense of decreasing
	the available swap in the 'b' slice following the sparing area.
	The net effect is you could trade a system with swap that has
	too many bad sectors to operate correctly for a system that
	will operate correctly but has slightly less swap.
