The reason is that when two IDE devices share a controller, they must also share the controller’s resources. For example, if one controller contains a hard drive and the other contains a Zip drive, you’ll want the CD drive to share the controller that’s connected to the Zip drive. If your computer contains two IDE controllers and both are already in use, you’ll want to connect your CD drive to the controller that contains the less frequently used device. Therefore, if you don’t have a controller free, you can daisy chain the new CD drive to another IDE device such as a hard drive or another CD drive.
Ideally, you’ll want your CD drive to be the only device on an IDE controller, but you can have up to two devices per controller. Most newer computers contain two IDE controllers, although some only contain one. Note that although the number of pins will always be the same, the controller’s markings and location will differ among various brands of computers. Your CD drive plugs into an IDE controller like the ones shown in Figure A. This is what an IDE controller looks like. At this point, you’ll have to make some decisions about the way you’ll be connecting the CD drive. (A quick look at the front of the PC will tell you what you need to know.) Once you’ve done so, shut down the computer, unplug it, and then carefully remove the cover. The first step in the installation process is to verify that your computer has an empty drive bay into which you can install the new CD drive. Since IDE is the more common type of CD drive, I’ll be using an IDE drive in my example. In this article, I’ll walk you through the installation procedure.
Now that you’ve picked out your CD drive, it’s time to install it.
