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 AUTO-
EXEC.BAT file for the statement C:\DOS\MSCDEX.EXE
/D:MSCD000 and CONFIG.SYS file for the statement
DEVICE=C:\ASUS_CD\ ASUSCD.SYS /D:MSCD000 (see
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
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 CD
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.
