IDE CD-ROM Installation Procedures
[Back to Hardware Help Index]
[Back to Jim's Home Page]
On a typical IDE CD-ROM drive as pictured above, there are three cable connections on the back side, four large pins
for power, four small pins for an audio cable, and a forty pin IDE cable connector. There are also jumpers to designate
the drive as a slave or master.
IDE drives use the existing computer hard drive IDE interface to transfer data to the computer. They may be connected in
lieu of a second hard drive. Newer motherboards and/or controllers may have two IDE interfaces, each supporting a
maximum of two IDE devices. If the CD-ROM is the second of only two IDE devices in the system, it may be installed on
the same cable as the hard drive, and jumpered as a slave (place a jumper on the two pins under the letters SL). If
there are already two IDE drives in the system, the CD-ROM may be jumpered as master and connected by a separate IDE
cable to the secondary IDE port or to a sound card that has an IDE interface.
IDE cables have forty pin connectors, one on each end, and an optional third connector in the middle. All connectors are
identical. The red stripe on the IDE cable should always be matched to pin one on all IDE devices and controllers. IDE
devices may be connected in any order, however the controller may not be attached to the center connector.
If you wish to play audio CDs through your sound card, plug the audio cable into the back of the CD-ROM. The other end
of the cable is plugged into a receptacle on the sound card.
After the physical installation, drivers must be loaded before you CD-ROM will be functional. Consult the CD-ROM
documentation for instructions, or see the README.TXT file on the driver disk supplied with your CD-ROM.
