Installing Your CD-ROM Drive

Before installing your CD-ROM Drive into your computer (see Quick Installation Guide
for instructions on installing your CD-ROM Drive), set your drive as either the Master or
Slave (default) drive by placing the jumper cap on the desired jumper ➂.

Slave Drive (Default) Master Drive

NOTE: If your computer only allows you to connect a maximum of two devices and you
have two hard disks, remove the Slave hard disk—you need the other IDE connector for
your CD-ROM Drive. If you only have one hard disk, set your CD-ROM Drive as Slave. If
your computer has two IDE connectors and two hard disks installed, either set your CD­ROM Drive as Master on the secondary IDE connector or remove the Slave hard disk and
replace it with your CD-ROM Drive. Refer to your computer’s manual for your system’s
configuration and instructions on hardware installation.

II. SOFTWARE INSTALLATION

After you have installed the CD-ROM Drive into your computer, the drivers neces­sary to run the drive may now be installed. The CD-ROM Drive comes with an
ASUS CD/DVD-ROM Driver for DOS/Win 3.X Installation disk.

In addition to the hardware-dependent driver, a software-dependent driver is installed:
MSCDEX.EXE (version 2.21 or later), which is the Microsoft CD-ROM Extension, a
standard mechanism for interfacing CD-ROM drives with computers. The driver comes
with your operating system (OS), for example, MS-DOS.

DOS/Windows 3.x

1. Restart your computer in DOS Mode.

2. With the installation disk into either drive A or drive B, type A: install (or B:
install) and then press [Enter].

3. Choose your preferred setup option and then follow the onscreen instructions.

4. Highlight Start Installation and then press [Enter]. The installation utility will
update your AUTOEXEC.BAT and CONFIG.SYS files with the appropriate
settings and create the other options that you chose.

5. After the installation is completed, restart your computer.

II. S/W INST ALLATION

DOS/Windows/Others

Setup Options

T wo setup options are available: Express Setup, for quick and easy installation; and
Custom Setup, for customized installation settings, such as the target directory for

the driver and installation files, and special settings. For most users, Express Setup,
which installs the default CD-ROM driver setting, works just fine.

Transfer Mode (DOS only)

T o take advantage of the special settings to fully use your drive’s capability, highlight
T ransfer Mode under the Custom Setup dialog box and then press [Enter]. The dif­ferent transfer mode options will be displayed, namely, PIO Mode or Programmed
Input/Output Mode, Multi-word DMA Mode or Multi-word Direct Memory Access
Mode, and Ultra DMA Mode, also known as Ultra-ATA or Ultra-DMA/33.

NOTE: These special settings require that you have a motherboard or install an adapter that
supports either or all of these modes. If your system supports it, select DMA Mode (prefer­ably Ultra DMA Mode) for better performance.

Other Operating Systems

If your CD-ROM Drive is already installed, Windows 9x or Windows NT (see IV.
Troubleshooting for information on maximizing your drive’s capability) will auto-

matically detect it and determine the appropriate settings for the drive and install or
load the correct driver. Your CD-ROM Drive supports the AT API drive interface. Thus
other systems, such as Linux and OS/2, should be able to automatically detect your
CD-ROM Drive and load the appropriate device driver.

IV. TROUBLESHOOTING

General Problems

PROBLEM Unable to access CD-ROM Drive.

CAUSES 1. The information in your CONFIG.SYS or AUTOEXEC.BAT or both files might

be incorrect. (DOS only.)

2. Some BIOS that include power management features use IRQ14 or IRQ 15,
which should be reserved for IDE devices like your CD-ROM Drive. (DOS only.)

SOLUTIONS 1. Check the LASTDRIVE= entry in your CONFIG.SYS file. You might have to

set the drive letter to one higher than your actual last drive letter. For example,
if the last drive on your system is drive D, try setting the parameter in the
CONFIG.SYS file to LASTDRIVE=E. (DOS only.)

• Your CD-ROM Drive requires the drivers, MSCDEX.EXE and ASUSCD.SYS,

to access the drive. Check your AUTOEXEC.BAT file for the statement
C:\DOS\MSCDEX.EXE /D:ASUSCD01 and CONFIG.SYS file for the state­ment DEVICE=C:\ASUS_CD\ ASUSCD.SYS /D:ASUSCD01 (see II. Soft-
ware Installation for more information). (DOS only.)

2. Change the IRQ setting of the device that is using IRQ 14 or IRQ 15, for ex­ample, sound card or motherboard. Refer to the card or motherboard documenta­tion for more information. (DOS only.)

PROBLEM Cannot detect the CD-ROM Drive (Windows 9x or Windows NT).

CAUSE There are times when Windows cannot detect a new hardware.
SOLUTION Install the drivers manually.

• Start the Add New Hardware wizard by double-clicking My Computer | Con-

trol Panel | Add New Hardware and then follow the instructions on your screen.

NOTE: Let Windows detect your CD-ROM Drive. Make sure you have installed and con­nected your CD-ROM Drive in your computer before running the wizard.

PROBLEM No sound from speakers.

CAUSES 1. Audio cable or speakers are not connected properly.

2. The volume is not adjusted to an audible level.

3. The drive may be faulty.

4. The card may be faulty.

SOLUTIONS 1. Check that the CD audio cable is connected to the Analog Audio line out connec-

tor on the drive and sound card. Check also that the pin definitions of your CD­ROM Drive and sound card are the same. If not, check with your dealer for a
compatible audio cable or ask a qualified technician to adjust the cables to match
your CD-ROM Drive’s pin definitions. Also, check that the speakers are con­nected to the correct jack on the sound card.

2. Make sure the volume control is turned up to an audible range.

3. Connect earphones or headphones to the Headphones Jack. If there is no sound
from your earphones or headphones, consult your dealer about your faulty drive.

4. Connect earphones or headphones to the sound card’s Headphones Jack. If there is no
sound from your earphones or headphones, check to see the audio cable is connected
from the drive to the sound card (refer to your sound card manual for more informa­tion). If the audio cable is connected and there is still no sound from your earphones
or headphones, consult your dealer about your faulty card.

IV. TROUBLESHOOTING

PROBLEM Cannot achieve the maximum data transfer rate performance specified for the CD-

CAUSES 1. If you are using a benchmarking utility, it may be old.

SOLUTIONS 1. Upgrade your benchmarking utility to one that supports tests on the outer tracks

IV. TROUBLESHOOTING

ROM Drive.

2. The disc is not full.

3. Given the signal quality issues with PIO Mode 4 transfer rates in some systems
and such variables as error correction, caching, processor overhead, and rota­tional speed, higher transfer rates may not be achievable with the default trans­fer mode. Thus transfer rates may be lower.

4. The disc you are playing may not be in a CD-ROM or CD-ROM format.

of your drive. Your CD-ROM Drive uses Constant Angular Velocity (CAV)
technology, wherein the spindle motor is running at the same velocity, while
the drive is accessing data at the inner or outer tracks. In this way, the drive will
achieve lower data transfer rates at the inner tracks and higher transfer rates at
the outer tracks. Thus using some or older benchmarking utilities, such as
WinBench 96, will give lower data transfer rates because these utilities use the
drive’s inner tracks for its performance tests.

2. A disc will occupy only the inner tracks when it is not full. Thus, because of the
way your CD-ROM Drive accesses data (see preceding explanation on CAV
technology), the drive will achieve lower data transfer rates. Use a full disc if
possible to get the maximum transfer rate from your drive.

3. Change the transfer mode of your CD-ROM Drive to Multi-word or Ultra DMA
Mode to maximize its capability.

• For DOS, see Transfer Mode under II. Software Installation for more information.

• For Windows 95 or Windows NT, Bus Master driver must be installed. Unless

your computer dealer installed the driver when you bought it or your mother­board supports Bus Master mode, Windows will not use bus mastering for your
CD-ROM Drive.

– Double-click My Computer | Control Panel | System | Device Manager |

CD-ROM controllers. If you are using bus master, PCI Bus Master will be
displayed. If not and your motherboard has the new PCI controller chipsets
from Intel, for example, the 440BX, but does not have a CMOS setting for
Bus Master mode, you may have to get the driver from Intel. Check with
your dealer for more information.

• If you do not have Bus Master driver under W indows 9x, double-click My Com-

puter | Control Panel | System | Device Manager | CD-ROM, right-click
ASUS CD-Sxxx and then click Properties | Settings. Under Options of the
Settings tab, click DMA to enable DMA Mode.

4. Your CD-ROM drive reads data at dif ferent speeds depending on the disc format.
Your CD-ROM drive performs at its best when it is reading a CD-ROM or CD­ROM format disc. With other formats, such as Audio CD or Video CD, data trans­fer rate performance may be slower than the maximum rate performance specified.

PROBLEM Cannot display the directory on an audio CD disc with the DIR command.

CAUSE The DIR command does not work with audio CD discs while in DOS. You can use

the command, however, to display the directory on a data CD.

NOTE: You can use the DIR command to display the directory on an audio disc while in
Windows using the command prompt or MS-DOS Prompt. Refer to your Windows manual on
how to find the command prompt.
