This unit accepts standard CD-ROM data discs, music CDs, and photo CDs, but not Macintosh CDs. Because it is ATAPI compliant, this unit conforms to industry standards for ease of configuration.   New CD-ROM drive technology This CD-ROM drive uses new CD-ROM drive technology that allows the drive to operate from a minimum of 12X to a variety of possible maximum speeds; the performance of the drive depends on the amount of data the CD you are using contains. The specific maximum speed will vary, depending on the drive purchased. The chart below illustrates how this new technology functions. Bits of information Data transfer Drive RPM The CD-ROM drive speed (RPMs) remains at a constant speed as the data transfer rate increases from 12X to the maximum transfer rate for the drive. When the CD reaches the maximum transfer rate, the CD-ROM drive speed gradually decreases to maintain a constant data transfer rate at that speed.   Configuring the CD-ROM Drive Most system boards feature both a primary IDE controller and a secondary IDE controller. Each of these controllers can have two devices attached to it. When two devices are attached to one controller, one is configured as master and one is configured as slave. For example, one hard disk drive in your system is always configured as the master device on the primary IDE controller. Depending on the number of hard disk drives in your system, the CD-ROM drive can be installed as slave on either the primary or secondary IDE controller; however, installation as master on the secondary IDE controller is recommended for best drive performance. Before opening your system case, read and follow these preventions and precautions to prevent damage from static electricity. Caution! Preventing Static Electricity Damage The components inside your system are extremely sensitive to static electricity, also known as electrostatic discharge (ESD). Static electricity can cause irreparable damage to your system; however, if you follow these preventions and precautions, you should prevent such damage. Static Electricity Preventions 1. WEAR A GROUNDING WRIST STRAP (available at most electronic stores). 2. Turn off the system power. 3. Touch the back of the power supply fan, located on the back of the case. 4. UNPLUG ALL CORDS FROM WALL OUTLET. 5. Remove the system case cover. Static Electricity Precautions • Avoid static-causing surfaces such as plastic and styrofoam in your work area. • Remove parts from their antistatic bags only when you are ready to use it. Do not lay parts on the outside of antistatic bags since only the inside provides antistatic protection. • Always hold cards by their edges and their metal mounting bracket. Avoid touching components on the cards and the edge connectors that connect to expansion slots. • Never slide cards or other parts over any surface.   To configure the CD-ROM drive: Locate the configuration jumper on the back of the CD-ROM drive. 1. Configuration jumper Place the jumper over the appropriate pair of pins to configure the drive as either a master or a slave device. 1. Master device setting 2. Slave device setting   Installing the CD-ROM Drive The CD-ROM drive cannot be used as an external device and must be installed in a drive bay. Plan to install the drive in a lower drive bay, because the IDE cable that connects it to the system board may not reach to a higher bay. Remove or rearrange devices as necessary to create space for the CD-ROM drive.   To install the CD-ROM drive: Power down the system. Remove the system’s case cover. For detailed instructions, refer to the documentation that shipped with your computer. Remove the drive bay cover of the bay in which you are installing the CD-ROM drive by inserting a small flathead screwdriver between the side of the bay cover and the front of the system case. Gently pry off the cover. 1. Drive bay cover 2. System cover Behind each bay cover you remove is a metal plate you also need to remove. On some systems, these plates can be popped out by hand. On many models, you have to remove screws, and on some of these, you must remove all the plates in order to remove the lowest one, because they are interlocked. If your system requires rails, install them on the CD-ROM drive exactly as they are installed on your hard disk drive. 1. Rail Slide the drive into the empty drive bay and fasten it into place using two screws on each of its sides. If your system requires rails, fasten the tabs on the front. 1. Tab Attach a 4-pin power supply cable from the system’s power supply to the power supply connector on the back of the drive. The cable is keyed so it only goes on the correct way. 1. Power supply connector Locate the IDE ribbon cable provided with the CD-ROM drive. Using one of the connectors that are placed closer together on the IDE ribbon cable, attach the IDE ribbon cable to the IDE ribbon cable connector on the back of the drive. Orient the cable so its red striped edge is aligned with Pin 1. 1. IDE ribbon cable connector 2. Pin 1; red stripe on ribbon cable aligns here Using the connector at the long end of the IDE ribbon cable, attach the IDE ribbon cable to the appropriate IDE connector (primary or secondary) on the system board. If you are using the recommended configuration, the drive is the master drive on the secondary IDE connector, so the cable is attached to the secondary IDE connector on the system board. Orient the cable so its red striped edge is aligned with Pin 1 on the system board; Pin 1 is marked on the system board. If you have a sound card, connect the sound cable to the audio connector on the back of the drive. Connect the other end to the internal audio input connector on your sound card. (If you received a new sound cable with your CD-ROM drive, remove any other sound cables connected to your sound card.) Tighten all connections. Replace the system cover.   Configuring the System Although your system treats the CD-ROM drive like a hard drive, you cannot write to it. Since the drive uses the IDE bus, no special controller card is necessary.   To configure your system: After physically installing the CD-ROM drive, power up your computer. Windows 95 automatically detects the drive and configures your system. Note: Even with automatic recognition and configuration, you may wish to add the following line to your system’s config.sys file in order to optimize DOS-mode support. (Be sure to enter the line as a single line of type with spaces in the appropriate places.) device=c:\cdrom\mtmcdai.sys /d:mscd001   Operating the Drive After installing and configuring your CD-ROM drive, check to see that your system recognizes it.   To check installation on your system: Power up the system. Double-click on the My Computer icon. When the My Computer window opens, look at the icons. Next to the icons for your hard disk drive (C:) and your floppy drive (A:) is the CD-ROM drive icon (D:). Depending upon the number of drives previously installed in your system, your CD-ROM drive may have a different letter designation, such as E:. 1. Drive tray 2. Emergency eject hole 3. Power button 4. LED 5. Volume control 6. Headphone jack   Playing an audio CD You may play audio CDs a number of different ways: Load an audio CD in the drive—Windows 95 plays it automatically (the CD Player button appears on the Taskbar; click on the button to view the CD Player) Use the CD Player application in Windows 95 If your system has a sound card, use the sound card software.   To play an audio CD with CD Player: Insert an audio CD into the CD-ROM drive. Click Start, Programs, Accessories, Multimedia, and CD Player. The CD Player control panel appears. Use the buttons on this control panel to play the CD.   Using sound card software If using your sound card software to play an audio CD, refer to the User’s Guide that came with the sound card.   Audio connectors/controls The hole near the left edge of the drive is a mini stereo jack suitable for headphones or powered speakers. You can also use it as an auxiliary input to a larger stereo system. The wheel to the right of the headphone jack is a volume control. We recommend you turn it all the way left (minimum volume) before you put on headphones, and then turn the volume up (to the right) after the CD starts.   CD software (data CDs) Many software programs are available on CD and can be installed on your system.   To install software from a CD: Insert a software CD into the CD-ROM drive. Click Start, then Run.... The Run dialog box appears. Type either: d:\setup OR d:\install in the command line provided, then press <ENTER>. Check the software documentation for the correct command line. Also, these instructions assume your CD-ROM drive is letter D:. If your CD-ROM drive is a different letter, substitute that letter. Follow the on-screen instructions.   Emergency eject You may encounter a circumstance when it is not possible or convenient to open the drive with the Open/Close button: for example, when the computer is powered down. You can still open the drive. First, power down the computer. Next, carefully insert a stiff wire such as a straightened, heavy-duty paper clip into the emergency eject hole until you feel resistance. Press just a bit harder and the drive tray slides out. Grasp the front of the tray and pull it out firmly but gently. It resists at first, but glides smoothly once it clears the CD-ROM case.   Troubleshooting Consult the following checklist if you encounter any difficulty operating your CD-ROM drive. Before checking any internal devices or connections, power down the system and remove the cover. After checking each item, replace the cover (don’t fasten the screws), and power up the system to see if it works. When everything works, fasten the cover in place. Are volume levels set properly? Are headphones or audio connections securely inserted in the proper jacks or connectors? Is amplifier or speaker power turned on? Is the CD free of scratches and residue and inserted correctly in the tray? Are all the necessary components’ power switches set to the on position? If you are using a power strip, is it set to the on position? Are the ends of the IDE ribbon cable and the power cord securely attached and not frayed? Are the edges of the colored cables aligned correctly? Are the jumper settings correct for the CD-ROM and the hard disk drive? Do the sound card settings match its manual? If these procedures fail to correct the problem, you can find our technical support numbers in your warranty.   Notices   All rights reserved This publication is protected by copyright and all rights are reserved.
