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 IDECD.SYS,
to access the drive. Check your AUTOEXEC.BAT file for the statement
C:\DOS\MSCDEX.EXE /D:IDECD01 and CONFIG.SYS file for the
statement DEVICE=C:\ASUS_CD\ IDECD.SYS /D:IDECD01 (see II.
Software 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 |
Control 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
connector 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 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.
IV. Troubleshooting
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.
