Troubleshooting the CD-ROM Drive During POST, the computer checks the CD-ROM drive, comparing its characteristics with the system configuration 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 calling 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 key combination. Does the hard-disk drive/CD-ROM drive access indicator blink during POST? Yes. Go to step 3. No. Go to step 2. 2. Remove the hard-disk drive and boot the computer. 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 operating 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 . Then type dir and press . 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 troubleshooting procedure again. If you continue to experience trouble, call Dell for technical assistance. (See Chapter 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 configuration 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 operation 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 SYSTEM SWITCH option in the System Setup program is set to ON/OFF. For instructions, see "Using the System Setup Program" in Chapter 2.
