and secure it to the bracket (2). (If the bracket was removed, re-install
it and secure it to the back of the controller.) Ensure that the jumpers
on the new drive are set to the Master setting.

Tip: There are two ribbon cable connectors side by side (shown in black and
blue in Figure 72 on page 206). Ensure that you connect the ribbon cable to
the connector nearest the hard drive. It is shown in blue in the figure.
