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. CAUTION: You must match the colored strip on the EIDE cable with pin 1 on the drive's interface connector to avoid possible damage to your system. IDE2 connector IDE1 connector Figure 7-13.
