Jumper settings

Positions 3 and 4 are used to park un-used jumpers. 

Default jumpers

Note: When a drive 1 (slave) is installed in the system with a drive 0 (master) already installed, there is no change to the jumper setting for a drive 0 (master). Only the jumper of drive 1 (slave), bit 2, is required to be removed. The jumper may be stored for later use by moving it to bit 3 which is unused.
