Learn the Jumper Functions
The jumper functions on the ATA drive are described in
Table 3. Note that jumper 0 is used for selecting single or
dual drive operation and that jumper 7 is used to prevent
the drive from entering manufacturing test mode if pin A1 is
momentarily grounded. Jumpers 1 through 6 are reserved
for future use and should always be left in place.
