HARDWARE INSTALLATION
This section describes how to install your CD-ROM drive into your computer.
Note: If you are not comfortable about opening your PC and attempting the CD-ROM
drive installation, many local computer shops can perform this service for a
reasonable cost.
This installation assumes you have a PC with an available connector on an IDE
interface cable. If your PC has an IDE hard drive, there is usually an available
connector in the middle of the same cable that attaches from the motherboard (or
controller card) IDE connector to the hard drive. If the last sentence does not describe
your system, you may need to purchase an IDE controller card to install this CD-ROM
drive. Inspecting and knowing your PC system will make your installation easier and
less time consuming.
A final note before installation: The cable connecting to your floppy disk drive is not an
IDE cable. Do not attempt to attach the CD-ROM drive to this cable.
If the CD-ROM drive is to be connected to the same cable as the hard drive, be sure
that the hard drive is set as master. Hard drives can be set as single, master, or slave.
Check your hard drive owner's manual or contact the hard drive manufacturer for
correct jumper settings.
SETTING MASTER / SLAVE JUMPER
*You will see three pairs of pins and a jumper (cap) at the back of the CD-ROM drive.
This jumper is used to set the CD-ROM Drive as a CSEL, MASTER, or SLAVE device in
your PC. Examples of how the jumper can be placed are shown in Figure 3 below.
*Move the jumper (clip on one pair of pins) from its default factory position (SLAVE), to
CSEL or MASTER as needed (see the following description for the setup that matches
your system), using the above diagram to place the jumper.
E-7
WARNING:
To protect the CD-ROM Drive, your computer, and peripheral devices from damage,
turn off their power before installing the drive.
8241B-Eng* 98.3.12 9:52 AM ∆‰¿Ã¡ˆ7

WHEN USING A PRIMARY IDE CONTROLLER
Most PCs provide one IDE cable to support two devices (one for hard disk, the other for a
second hard disk or a CD-ROM drive). This IDE cable originates either on the motherboard
or on a controller card. This controller is termed the primary IDE controller, and the hard
disk attached that contains the operating system for boot-up is set up as the Primary
Master. Your CD-ROM drive should be set to the Slave mode.
E-8
Note:
Many older 1X and 2X CD-ROM drives used a 40 pin controller card that were not
IDE compatible. These were proprietary interface cards for use with a particular
model CD-ROM Drive. Many older Sony, Panasonic, and Mitsumi drives used 40 pin
proprietary interface cards. If you are upgrading from an older CD-ROM drive, your
new CD-ROM will not work on a proprietary interface card. You will need to buy a
secondary IDE controller card.
8241B-Eng* 98.3.12 9:52 AM ∆‰¿Ã¡ˆ8

WHEN USING A SECONDARY CONTROLLER
*If your PC has an additional IDE controller on the motherboard or on a system slot, each
IDE device connected to the secondary IDE controller must also be set to the Master or
Slave mode. If you are connecting your CD-ROM drive to a secondary IDE card, and it is
the 1st device you are connecting to it, then set the CD-ROM jumper to the Master
position. If it is the 2nd device, set the CD-ROM jumper to the Slave position.
*Depending on the IDE card and whether the CD-ROM drive is a master or slave unit,
the diagram below represents the different ways in which the CD-ROM may be
configured in your PC. The table below the diagram shows the possible Jumper
placements that would correspond to each of the different configurations shown.
E-9
If you have the system with two IDE channels (in the case of an enhanced IDE PC),
do not install an IDE controller card in your system.

ATAPI Installation (Windows 95 and others)
*For Windows 95 installation, do not use the installation diskette supplied. This CD-
ROM drive is Windows 95, Windows NT 3.5, and OS/2 Warp compatible, generally
utilizing the generic software drivers supplied with those operating systems Below is
the example installing the driver for Windows 95. For other operating systems, try
looking for either a LG Electronics or Goldstar IDE CD-ROM drive software driver. If
none is found, try selecting one of the device drivers for Non-listed IDE CD-ROM .
(For Windows 95)
1. Install the CD-ROM drive in your PC as described in this manual.
2. Power up your PC. Upon starting Windows 95, it might automatically detect the new
CD-ROM drive and load the driver software for it. If not, proceed to the next step.
3. In Windows 95, Click on the Start button. Click on the Settings button. Click on the
Control Panel button. Double-Click on the Add New Hardware icon. Follow the
instructions for the computer to search your system for new hardware. It will locate
the CD-ROM drive and load the generic driver.
TROUBLESHOOTING
*When the CD-ROM drive does not work with the hard disk drive in primary
IDE channel.
(SOLUTION)
1. Check the CD-ROM drive Master/Slave Jumper setting.
The CD-ROM drive must be set to the Slave mode.
2. Check to be sure your hard disk Interface type is IDE type.
3. Check your hard disk Master/Slave Jumper setting.
Some old-version IDE type hard disks were set to Master Only mode.
In that case, contact your hard disk company and change your hard disk jumper
setting to master mode.
4. If the CD-ROM drive does not work with above methods, you may need a secondary
IDE card. If you use the secondary IDE card, you should set the CD-ROM drive
jumper to the master mode if the CD-ROM drive is the first device you are
connecting to the secondary IDE card.
*When the CD-ROM drive does not install in OS/2 warp.
(SOLUTION)
1. Select NON-LISTED IDE CD.
*CD-ROM drive is not present in Windows 3.1 or 3.11 or DOSSHELL.
(SOLUTION)
1. When the WTN or DOSSHELL command lines are present in your AUTOEXEC.BAT,
make sure that the MSCDEX.EXE command line appears before the WIN or the
DOSSHELL command lines.
