Troubleshooting Your Computer 3-23
Troubleshooting the CD-ROM Drive
During POST, the computer checks the CD-ROM drive,
comparing its characteristics with the system configura-
tion information. (The hard-disk drive/CD-ROM drive
access indicator blinks as the computer performs this
check.)
NOTE: If you are using MS-DOS only, check the
config.sys and autoexec.bat files before using the
following procedure. If necessary, add the following
statement to the config.sys file:
device=c:\tsy\tsycdrom.sys . If necessary,
add the following statement to the autoexe.bat file:
c:\dos\hscdex.exe /d:tsycdl . Then save the
changes and reboot the computer. If the problem persists,
use the following troubleshooting procedure before call-
ing Dell.
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. Turn off the computer, or reboot it by pressing
the <
CTRL >< ALT >< DEL > key combination. Does
the hard-disk drive/CD-ROM drive access indica-
tor blink during POST?
Yes. Go to step 3.
No. Go to step 2.
2. Remove the hard-disk drive and boot the com-
puter. Does the hard-disk drive/CD-ROM drive
access indicator blink during POST?
Yes. Go to step 3.
No. Go to step 6.
3. 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 4.
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.)
4. Insert a bootable diskette into drive A, and reboot
the computer.
The diskette must contain the same config.sys and
autoexec.bat files that are on the hard-disk drive.
5. 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 6.
6. Insert the 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 7.
7. Call Dell for technical assistance.
See Chapter 5, “Getting Help,” for instructions.
Troubleshooting the Hard-Disk Drive
During POST, the computer checks the hard-disk drive,
comparing its characteristics with the system configura-
tion information. (The hard-disk drive/CD-ROM 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.
NOTES: If you have another hard-disk drive that you
know is in good condition, install it in your computer
before you begin this procedure and perform the opera-
tion that caused you to suspect a hard-disk drive failure.
If there is no evidence of a drive failure with the second
drive installed, the first drive is probably defective. If the
second drive fails, reinstall the first drive and start the
following procedure.
Before you begin this procedure, make sure that the SYS-
TEM SWITCH option in the System Setup program is set to
ON/OFF . For instructions, see “Using the System Setup Pro-
gram” in Chapter 2.
