Troubleshooting C-2
Problem
Interface card or CD-ROM drive is not ready.
Causes
1. The power or data cable is not connected.
2. MSCDEX.EXE or SBIDE.SYS is not loaded.
3. Some BIOS that include power management
features use IRQ 12 or 15.
Solutions
1. Ensure the power and CD audio cables are
connected properly to the drive (see the section
“Installing Your Drive” in Chapter 2).
2. Your CD-ROM drive requires MSCDEX.EXE and
SBIDE.SYS to access the drive. Check your
AUTOEXEC.BAT file for the statement
C:\path\MSCDEX.EXE /D:MSCD001 /M:8 /V
and CONFIG.SYS file for the statement
DEVICE=C:\path\SBIDE.SYS /D:MSCD001
/P:1E8,11 /V
(see the section “Changing the
Driver Settings” in Chapter 4 for more information).
If you have connected the drive to the hard disk
controller card, the statement added to your
CONFIG.SYS file is
DEVICE=C:\path\SBIDE.SYS /D:MSCD001
/P:1F0,14 /V
3. Change the IRQ setting of the audio or IDE
CD-ROM interface card. Refer to the
documentation for more information.
Problem
Not enough drive letters available.
Cause
You have installed more than 3 logical or physical
drives in your system.
Solution
Modify the LASTDRIVE statement in your CONFIG.SYS
file to reflect the maximum number of drives you can access. For
example, if you have installed 5 drives in your system, your current
LASTDRIVE statement in your CONFIG.SYS file will be
LASTDRIVE=E. Change this statement to LASTDRIVE=F if you
want to install an additional drive to your system. See your DOS
manual for more details.
