ANS:C - on the secondary IDE

An EIDE (Enhanced Integrated Drive Electronics) adapter, connect at ATA (Advanced Technology Attachment) CD-ROM drive?

Advanced Technology Attachment

Short for Advanced Technology Attachment, ATA was approved on May 12, 1994, and is an interface that connects hard drives, CD-ROM drives, and other drives.

ATAPI (AT Attachment Packet Interface) is an interface between your computer and attached CD-ROM drives and tape backup drives. Most of today's PC computers use the standard Integrated Drive Electronics (IDE) interface to address hard disk drives.

ATAPI CD-ROM drives are installed just like any other ATAPI/IDE device. Other than physical installation, the only decisions you need to make are whether to install the drive on the Primary or Secondary ATA interface and whether to jumper the drive as Sole, Master, or Slave. In general, use the following guidelines:

On a system with one or two ATA hard drives and one ATAPI CD-ROM drive, install the first hard drive as Primary Master (PM), the second hard drive, if present, as Primary Slave (PS), and the CD-ROM drive as Secondary Master (SM).

On a system with three ATA hard drives and a CD-ROM drive, install the first hard drive as PM, the second hard drive as PS, the third hard drive as SM, and the CD-ROM drive as Secondary Slave (SS).
