3.3.2 Cable select option
Computers that use cable select determine the master and slave drives by
selecting or deselecting pin 28, CSEL, on the interface bus. Master and slave
drives are determined by their physical position on the cable. To enable cable
select, set a jumper on pins 5 and 6 as shown in Figure 4. Refer to your
computer manual to determine whether your computer supports this option.
