3-24 Option Installation
Diskette Drive Signal Cable
A three-connector diskette drive signal cable comes attached to the system board and to the
standard 1.44-MB diskette drive.
The installation of a second diskette drive in your system does not require the replacement
of the existing diskette drive signal cable. Connect an optional diskette drive to the middle
connector on the standard diskette drive signal cable.
The colored edge of the cable goes to pin 1 on the cable connector. Align the red edge of
the cable with pin 1 (the notched end) on the drive connector.
Figure 3-22 shows a three-connector diskette drive signal cable.

IDE Signal Cables
Hard disk systems come with a three-connector IDE interface cable attached to the primary
IDE connector. Multimedia systems come with a second IDE cable connected to the CD-
ROM reader and to the secondary IDE connector.
Each IDE connector on the system board supports two IDE devices. The addition of an
IDE device to an IDE connector does not require the replacement of the existing IDE signal
cable.
If installing an optional IDE CD-ROM reader, connect it to the secondary IDE connector.
The primary (fast) IDE port should be reserved for hard disks.
