Troubleshooting the CD-ROM Drive
During POST, the computer checks the CD-ROM drive,
comparing its characteristics with the system configura-
tion information. (The CD-ROM/hard-disk drive access
indicator blinks as the computer performs this check.)
If a failure occurs with the drive, make a copy of the
Diagnostics Checklist found in Chapter 5 and fill it out as
you complete the following procedure:
1. Install the CD-ROM drive in the options bay.
Reboot the computer by pressing the
<
CTRL >< ALT >< DEL > key combination. Does the
CD-ROM/harddisk drive access indicator appear
in the status display panel during the boot
routine.
Yes. Go to step 3.
No. Go to step 2.
2. Remove and reinsert the CD-ROM drive. Reboot
the computer. Does the CD-ROM/hard-disk drive
access indicator appear in the status display panel
during the boot routine?
Yes. Go to step 3.
No. Go to step 7.
3. Remove the hard-disk drive and boot the com-
puter. Does the CD-ROM/hard-disk drive access
indicator appear in the status display panel?
Yes. Go to step 4.
No. Go to step 7.
4. Reinstall the hard-disk drive. Then check the
config.sys file (in the Microsoft Windows 95 oper-
ating system, check the CD-ROM configuration
in the Settings folder). Is the CD-ROM driver
(tsycdrom.sys) installed?
Yes. Go to step 5.
No. Load the driver and return to step 1 to begin this
procedure again. (To load the driver, use the program
diskette sets you made when you first received your
Dell computer.)
5. Insert a bootable diskette into drive A, and reboot
the computer.
6. Type d: and press < ENTER >. Then type dir and
press < ENTER >. Does MS-DOS display the root
directory contents for drive D?
Yes. The problem is resolved.
No. Go to step 7.
7. Insert your Dell diagnostics diskette into drive A,
and reboot the computer. Then run the IDE CD
ROM Drives Test Group. Does your CD-ROM
drive pass all the tests?
Yes. Return to step 1, and perform this troubleshoot-
ing procedure again. If you continue to experience
trouble, call Dell for technical assistance. (See Chap-
ter 5, “Getting Help,” for instructions.)
No. Go to step 8.
