16 head logical architecture is enabled. Master is set to on (i.e. jumper on pins A-B and G-H) No other jumpers are fitted.  Some systems may require you to use the 15 head logical architecture. This is because they translate a drive greater than 4 GB by multiplying the head count by 16.  The result (16 x 16 = 256) is interpreted as 0 heads with a 0 capacity and is an illegal head count.  Selecting the 15 head logical jumpers produces a legal translation (16 x 15 = 240).  The translated cylinder count varies to achieve the drive's full capacity.
