ATA-PI CD-ROM Drive — Upgrade Note

General instructions for installing a 5.25" device in the Apricot XEN-PC’s removable media drive bay are included in the documentation supplied with the computer.

This Upgrade Note provides additional information to help you fit and cable the ATA-PI CD-ROM drive correctly. Two cables are provided with the drive: a signal (ribbon) cable, and a CD-audio cable. The signal cable is aways required. The CD-audio cable is needed only if you are upgrading an Apricot XEN-PCls computer fitted with a multimedia daughterboard.

• Before installing the drive, ensure that the Master/Slave/CSEL jumper on the rear of the drive is set to the Master position.
• The drive should only be connected to the motherboard’s secondary ATA/IDE interface. Apricot does not recommend the use of this drive on the primary ATA/IDE interface, either directly or "daisy-chained" to a hard disk drive. (The primary ATA/IDE interface is on the PCI local bus; there would be no benefit in attaching a relatively "slow" device such as a CD-ROM to this interface.).
• There is a "kink" or fold in the signal (ribbon) cable. The end nearest the fold plugs into the motherboard; the other end plugs into the rear of the drive.
• Hint: In an Apricot XEN-PCls you may find it easier to plug the signal cable into the motherboard before installing the CD-ROM in the bay. Otherwise the multimedia daughterboard might get in the way.
• In an Apricot XEN-PCls system, you should connect the CD-audio cable between the drive and the multimedia daughterboard. Use the diagram provided in the Networking, Audio and Security Supplement to locate the daughterboard’s CD-audio connector.

An MS-DOS device driver ATAPI_CD.SYS is provided with the drive; for more information, view the accompanying Windows Help file.
