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.
