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.)
YourCD-ROMDriverequiresthedrivers,MSCDEX.EXEandASUSCD.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 state-
ment 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 ex-
ample, sound card or motherboard. Refer to the card or motherboard documenta-
tion 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 con-
nected 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 CD-
ROM 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 con-
nected 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 informa-
tion). If the audio cable is connected and there is still no sound from your earphones
or headphones, consult your dealer about your faulty card.
