7. Reinstall the hard-disk drive/bracket assembly in
the chassis.
Grasp the bracket by the tab containing the captive
screw, and hold the bracket at a 45-degree angle to the
chassis floor. Align the two tabs on the other side of
the bracket with the score marks on the chassis floor.
Insert the two tabs into the slots in the chassis floor
divider, and rotate the assembly downward. Then
tighten the captive screw until the bracket is securely
fastened to the chassis floor (see Figure 7-11).
8. Connect one end of the EIDE cable to the 40-pin
interface connector on the back of the hard-disk
drive (see Figure 7-13).
The cable is keyed so that the colored edge of the
EIDE cable lines up with the pin-1 end of the
interface connector.
